How many types of articles are there? Articles are generally divided into narrative, expository and argumentative.

Narration:

1, description-oriented. Mainly to express people, scenery and things clearly. People who remember things should explain the time, place, people and events clearly. Usually, the central idea is clear and concise. Narration can be divided into three basic forms: positive narration, flashback and interpolation. Rich in vocabulary and sentences, it is the simplest style to practice writing.

2. Narrative is an article that writes people's notes. According to the needs of the content, description, lyric, explanation and discussion can be interspersed. General narrative has six elements: the cause, process, result, character, place and time of the event. We can write, flashback, insert or supplement the narrative in chronological order. General requirements of narrative: true feelings. The content is specific and focused. The structure is clear and complete.

Explanatory text:

1, mainly used to describe and explain things, without too much gorgeous decoration. It just shows the characteristics of things themselves. There are many ways to explain things, such as drawing pictures, listing formulas and so on.

2. Explanatory writing is an article that explains things and reasons. It takes description as the main form of expression, scientifically explains the nature, characteristics, causes and functions of things, and aims at spreading knowledge.

The general requirement of expository writing: the content must be scientific and knowledgeable. Explain an argument or viewpoint in a hierarchical and orderly manner. The text is concise.

Argumentative paper:

1. Style used to express the author's point of view. Arguments should be used to demonstrate arguments. Several sub-arguments can enrich a main argument. Arguments include practical arguments and theoretical arguments. Argumentation can be demonstrated by examples, comparative arguments and counter-arguments.

2. Argumentative writing is a style used to analyze things, clarify opinions and propositions. It takes discussion as the main form of expression. General requirements for the thesis: at the beginning, set a position or argument according to the scope specified in the topic. According to the arguments held, put forward strong arguments or reasons to convince readers. The level must be clear and the language should be concise.

According to different uses, packaging is divided into several types. It's my pleasure to answer your question!

Export packaging is generally divided into transportation packaging and sales packaging. There are many functions of export commodity packaging, which can be roughly summarized as the following three aspects:

(A) the protection function

Protection function is the most basic function of export commodity packaging. In order to ensure that the quality and quantity of export commodities are not damaged or deteriorated during transportation, storage and sales to foreign markets, we should pay attention to the following eight points:

1. According to the shape, characteristics, transportation environment, sales environment and other factors of export commodities, adopt appropriate packaging materials and design reasonable packaging structure to protect export commodities. For example, in the past, the inner packaging design of silk clothing was not good, the packaging gap was too big, the sealing was not firmly bonded, the box cover often sank, and the packaging belt was easy to fall off. After export, due to poor packaging, clothes were stolen seriously, leading to claims. Then the original stacked boxes were changed into flat boxes, sealed with plastic tape and sealing nails, and finally sealed with seals, so that the anti-theft ability was greatly improved, and foreign businessmen were very satisfied with the new packaging.

2. In packaging design, we should not only consider the physical and chemical forces generated by packaging machinery on packaging materials, such as punching, pulling, twisting and pressing, but also choose packaging materials that can withstand these external forces to protect the contents, and also consider the damage caused by shaking, sudden braking, top-shaking and falling in the process of commodity circulation, so as to take corresponding measures to strengthen packaging strength.

3. Warehousing and stacking will make the containers and contents at the lower part of the stack bear great weight. In order to prevent damage to the packaging container or inner container, the pressure resistance of the packaging structure should be considered.

One of the functions of packaging is to hold the goods. Gaseous, liquid and powdery articles cannot be transported and sold without packaging. Therefore, the packaging material should be able to resist the chemical corrosion of the contents. For example, some detergents in shampoo may cause environmental stress cracking of polyethylene bottles or delamination of composite films, and isopropyl myristate contained in some cosmetics may soften polystyrene. In addition, external chemical and dust pollution should also be considered. Sometimes it not only pollutes the goods themselves, but also pollutes the patterns of the packaging itself. For example, in petrochemical enterprises and other fields, sulfurous acid gas in the atmosphere changes chemically with packaging and printing ink, which will cause fading.

5. Friction resistance is also a protection aspect. Because the goods jump or rotate in the package during transportation, it will cause surface friction and make its trademark or other marks unclear, especially when using raised patterns or bronzing words. Therefore, various lining structures should be used to fix or isolate goods to reduce friction.

6. Pay attention to the climate difference between export manufacturers and foreign target markets, as well as the seasonal temperature and humidity changes along the way. If the packaging materials can't adapt to these changes, the packaging and contents will crack, break, degrade and rust.

7. Illumination will not only make the printing surface pale, but also cause food deterioration and drug failure. Therefore, light-resistant ink can be used to prevent the pattern of packaging from changing color, and light-shielding materials such as metal, aluminum foil, colored glass, colored plastic and opaque paper can be used to prevent the content from deteriorating due to light.

8. The protection function of packaging also includes rust prevention, moisture prevention and theft prevention. Insect-proof, mildew-proof, fragrance-preserving, sterilization, heat-proof, cold-proof and waterproof. All these should be designed with different protection functions according to the nature, shape and function of the exported goods and different factors related to the domestic and foreign marketing environment (including foreign laws and regulations on packaging), and the relevant details will be discussed in the following chapters.

Convenience function

1. The production is convenient. For mass-produced export products, of course, the first consideration is their marketability, but we should also take into account the resource capacity and production cost of export manufacturers, so that the two can cooperate organically. For example, a carton with exquisite design has strong shelf impact, but if it is impossible or difficult to carry out assembly line production, it will also bring trouble to production.

2. Convenient filling. There should be a proper gap between export packaging containers and commodities. Because there is a certain size deviation between them, the action of packaging machinery also has a certain deviation. If there is no gap between them, the packaging operation cannot be carried out. If you pack by hand, there will be no gaps, which will lead to a decline in production efficiency. The structural design of bottles and cans should also consider the convenience of filling.

3. Convenient storage and transportation. The weight and volume of each packaging container should be suitable for its transportation characteristics (including the size of trucks and containers, etc.). ), stacking and handling requirements in the process of transportation at home and abroad and relevant regulations abroad, in order to reduce losses, avoid waste and improve transportation capacity and economic benefits. For example, the packaging design must adapt the packaging size to the selected stacking method and the maximum effective storage height. For another example, Chile stipulates that each bag of grain should not exceed 80 kilograms. Goods that meet the requirements should be hoisted by hand, and goods that exceed the requirements should be hoisted by iron hooks. Syria stipulates that the net weight of each oil product shall not exceed 10 kg; Belgium, the Netherlands, Germany, France and Britain stipulate that the carton size is 10-20kg, because the carton is too small to be stolen, but it is not easy to carry over 20kg. In addition, liners in various countries charge surcharges for extra-long and overweight goods. Many countries have different tax rates for the weight of each package of different goods.

In packaging design, in order to facilitate loading and unloading, attention should be paid to the application of ergonomic principles. Manual loading and unloading, weight, the general unit packaging weight is limited to about 20 kg; If continuous loading and unloading is carried out, the weight of the loaded and unloaded objects should generally not exceed 40% of the workers' weight, which is too large to be transported. Weight and volume should be considered in mechanical loading and unloading, and the cooperation between spreader and package should also be considered.

4. Easy to display and sell. This is an important means of promotion. There are many successful examples in both structural modeling and design. For example, hanging packaging and stacking packaging can make full use of supermarket space and save commodity space; Window opening, unfolding, supporting packaging, series packaging, group packaging and various portable packaging are all good forms to facilitate sales.

5. Easy to open. Transport packaging should be easy for retailers to open, and sales packaging should be easy for consumers to open. Elephant belt sewing

How many kinds of panels are there? There are more than 200 types of panels, five of which are the most common types: dry, neutral, mixed, oily and problematic (sensitive and acne).

How many kinds of glass are there? Flat glass:

Flat glass is a traditional glass product, which is mainly used for doors and windows, and has the functions of light transmission, wind resistance and heat preservation. Colorless, good transparency, smooth surface and no defects are required.

The thickness of flat glass is divided into 2 mm, 3 mm, 4 mm, 5 mm and 6 mm, and the single sheet size is 300 mm× 900 mm, 400 mm×1600 mm and 600 mm× 2200 mm. Its visible light reflectivity is about 7%, and its light transmittance is between 82% and 90%.

Embossed glass:

Embossed glass, also known as patterned glass and knurled glass, is mainly used in doors and windows, indoor partitions, bathrooms and other places.

Embossed glass has a pattern on the surface, which can transmit light, but it will block the line of sight, that is, it has the characteristics of light transmission and light impermeability, and the decorative effect is excellent.

The perspective effect of embossed glass varies with distance and pattern. Its perspective can be divided into: almost transparent and visible, slightly transparent and visible, almost invisible and completely invisible. Its types are: embossed glass, embossed vacuum aluminized glass, three-dimensional embossed glass, color film embossed glass and so on. The thickness is 3 ~ 5mm. It has many specifications and can be divided into diamond embossing and square embossing. When installing, the pattern faces inward to prevent dust.

Insulating glass:

Insulating glass consists of two or more layers of ordinary flat glass. The periphery of two or more pieces of glass is bonded and sealed with sealing strips and glass strips with high strength, high air tightness and high flexibility, and the middle is filled with dry gas, and the frame is filled with desiccant to ensure the air between the glass pieces to be dry. Its characteristics, due to a certain cavity, have good insulation, heat insulation, sound insulation and other effects. Mainly used for the outer glass decoration of heating, air conditioning and noise elimination facilities. Its light efficiency, thermal conductivity and sound insulation coefficient should meet the national standards.

Tempered glass:

Tempered glass is also called tempered glass. It is a kind of glass, which is heated to a certain temperature and then cooled quickly, or specially treated by chemical methods. It is characterized by high strength, and its bending strength and impact strength are 3-5 times higher than those of ordinary flat glass. Safe and efficient, uniform internal stress, and no net cracks after crushing. Mainly used for doors and windows, partition walls and cupboard doors. Tempered glass is also acid and alkali resistant. The general thickness is 2-5 mm.

Wired glass:

Laminated glass is also called shatterproof glass. It is made by heating ordinary flat glass to a red-hot softening state, and then pressing preheated iron wire or wire mesh into the middle of the glass. It is characterized by excellent fire resistance, can block the flame, will not burst when burning at high temperature, and will not cause debris to hurt people when broken. In addition, there are anti-theft effects, glass cutting and barbed wire blocking. Mainly used for roof skylight and balcony window.

High performance insulating glass:

In addition to sealing dry air between two layers of glass, high-efficiency insulating glass should also be coated with a special metal film with good thermal efficiency on the air layer side in the middle of the outer glass, which can block the energy of solar ultraviolet rays from entering the room. Its characteristics are good energy-saving effect, heat insulation and improvement of indoor environment. There are eight colors in appearance, which has excellent decorative art value.

Glass mosaic:

Glass mosaic is also called glass mosaic or glass paper skin brick. This is a small colored decorative glass. General specifications are 20mm× 20mm, 30mm× 30mm and 40mm× 40mm. The thickness is 4-6mm. Belonging to small glass mosaic materials of various colors. The appearance is colorless, transparent and translucent, with gold and silver spots, patterns or stripes. The front is shiny, smooth and delicate; There are rough grooves on the back, which are easy to paste with mortar. Its characteristics are: soft, concise, elegant, elegant, good chemical stability, good cold and hot stability and so on. Moreover, it has the characteristics of no discoloration, no dust accumulation, light bulk density and firm bonding, and is mostly used for indoor areas and balcony exterior wall decoration. Its compressive strength, tensile strength, first frost temperature, water resistance and acid resistance should meet the national standards.

Laminated glass:

Laminated glass is a kind of safety glass. It is a flat or curved composite glass product formed by inserting a transparent plastic sheet between two or more flat glasses and then hot pressing and bonding. Its main feature is good security. When broken, the glass fragments will not scatter, but only produce radial cracks, which will not hurt people. The impact strength is better than that of ordinary flat glass, and it has good crime prevention. It also has special functions such as light resistance, heat resistance, moisture resistance, cold resistance and sound insulation. Mostly used for outdoor door and window edging.

Organic glass and inorganic glass

There are several types of cough. Cough is a protective respiratory reflex action of human body. Cough is caused by the impulse of foreign body, qi, respiratory secretions and other receptors of respiratory mucosa to transmit to the cough center of medulla oblongata through afferent nerve fibers.

The action of coughing is a short and deep inhalation, the glottis are closed, and the respiratory muscles, intercostal muscles and diaphragm contract rapidly and violently, so that the high-pressure gas in the lungs is ejected, which becomes a cough. With the rapid flow of air, foreign bodies or secretions in the respiratory tract are excreted.

Cough reflex

Cough reflex arc includes four links:

(1) Respiratory nerve terminal receptors, including mechanical receptors, chemoreceptors and lung stretch receptors.

(2) The afferent nerve is vagus nerve fiber.

(3) The cough center of the medulla oblongata is located in the dorsal part of the medulla oblongata, adjacent to the respiratory center.

(4) Efferent nerves, including vagal efferent fibers, superior laryngeal nerves and cranial nerves. They cooperated to complete the cough.

There are many reasons for coughing. In addition to the respiratory organs such as nose, pharynx, larynx, trachea, bronchus, lung and pleura, the vagus nerve of organs such as ears, meninges, heart, esophagus and stomach is affected by * *, which will also be introduced into the cough center to cause cough.

Cough is the main symptom of respiratory diseases, such as cough without phlegm or dry cough, which is common in the early stage of acute pharyngitis and bronchitis. Acute sudden cough is more common in bronchial foreign bodies; Long-term chronic cough, more common in chronic bronchitis, tuberculosis and so on.

The adverse reaction of cough is that it can spread tracheal lesions to adjacent bronchioles and make the condition worse. In addition, persistent severe cough will affect rest, easily consume physical strength, and can cause the destruction of elastic tissue of alveolar wall and induce emphysema.

How many kinds of dance music are there? Brief introduction of dance music types

It's a little long Look carefully. Very useful.

Rap dance originated in 1960s, and its BPM is about 100- 1 10, which is translated as "rap and rap" in Chinese. Rap was a popular music among black youth at that time. It is a very strange music type: it replaces the melody part of music with human voice singing, plus clear and rich drum rhythm; Rap, a catchy popular lyric, has suddenly become a favorite of young people. Rap was once only the specialty of black singers, but soon some white bands joined in. Rap dance music became popular in 1960s, which made many dance music works incorporate some elements of rap. The emergence of rap is very remarkable.

Reggae originated in 1960s, and its BPM is about 80- 100 beat. Chinese translated into "Reggae". According to research, reggae dance originated in Jamaica, and then gradually spread to all parts of the world. Reggae pays more attention to drums and voices in music. Reggae, like Fink, has obvious rhythm and fixed melody line. It's just that modern reggae is mixed with some R&; The music styles of B and Hip-Hop have the same ups and downs as rumba when listening to Reggra, but the enthusiasm and lightness of reggae can still be clearly reflected from the light and heavy beats of four or four beats (two or four beats), so some people say that reggae is summer music.

Funk dance originated in 1960s, with BPM below 120 beat, and Chinese translation is "funk music". Funk dance is also a kind of music originally belonging to blacks. Electric bass plays a very important role in Funk dance music, and its chords and rhythms have become the backbone of Funk. Funk dance was very popular in the 1970s and 1980s. Due to the integration with other music, the current Funk has undergone some mixed-race changes in speed and music creation. Because Funk's music tastes too typical and strong, there is no popular trend at present, and it only appears in a few music works.

Disco appeared in the 1970s, BPM was around 120 beat, and Chinese translation was "disco". The popularity of disco should be attributed to the masterpiece of movies: disco dance music was widely used in American movies in the 1970s. Because the rhythm is simple (4/4 beat), the melody is positive and easy to be accepted by people, and the worship of stars has set off a disco trend in the United States and even the world. Disco is not only a dance music style, it is the initial starting point of advocating fashion trends today. If there were no discos at that time, maybe our life would still be black and white now. China people began to accept dance music culture from disco, and it is precisely for this reason that dance music is still called "disco" in many places in China. Disco is actually only a small part of the development of dance music.

House originated in 1970s, and BPM was around 130 beat. Family dance music is another popular music developed after disco. It consists of an electronic musical instrument and a sampler. Maybe it's because of the arrival of the electronic age? House is full of weird electronic synthesizers and sound effects, and its BPM is also suitable for young people's * * * and crazy investment. In the city that pursues the pleasure of life, house music is more in line with the tastes of modern people, and its appearance has also brought some negative effects such as alcoholism and drug abuse. In quite a few dance halls in China, indoor dance music is still very popular.

Hip-hop originated in 1980s, and BPM was 90- 1 10. Life before Hip-Hop was rap and a little r&; B, plus the sound effects of various grinding films, belongs to the music that young people love to play since the 1980s. Hip-Hop dance literally means hip, Hop is one-legged jump, and Hip-Hop is gently twisting the hips. Hip-Hop contains Rap and r &；; B The complicated rhythm and sound effects of the record player, as well as graffiti on the wall, are also extensions of hip-hop culture. Leisure and healthy (drug-free) parties are easy to make friends with the help of Hip-Hop.

Pop dance originated in the mid-1980s, with BPM of 100 beat-130 beat. In fact, some dance music that is different from the classical style and difficult to distinguish can be included in the category of pop dance music. Pop dance music refers to a form of dance music that combines pop music with dance rhythm. With the prevalence of disco at that time, some dance music combined with the pop music style at that time began to be welcomed by young people. Coupled with the emergence of MTV, a new form of music packaging, this kind of dance music was spread by pop stars at that time with the help of movies, TV and its emerging MTV, forming the so-called pop dance music. Pop dance music was produced by Madonna and Michael Jackson in the early days, and now there are also popular spice girls and Backstreet Boys.

The BPM of R& dance music B is about 80 to 100 beat, which is translated as "rhythm and blues or rhythm and blues" in Chinese. Pop music that used to be in the black life circle. The earliest research and development. B is a mixture of blues and jazz, which is the embryonic music from slow dance to rhythmic dance. R & ampb focuses on the obvious rhythm or beat, and its melody is also very clear, which often leaves a deep impression after listening. Due to people's superior material living conditions and the influence of retro trend; At present, R& ampb has become the darling of pop music, of course, it is the modern R&; Mixed with some elements of other music.

high energy

A variety of disco, which stores the roots of the genre in the mid-1970s and incorporates the factors of TECHNO. Its characteristics are: rendering melody, vocal control, happiness, high * * * and maintaining at118 ~140 BPM.

alternative energy sources

It is impossible to classify them simply. Its characteristics are: high acceptance, extensive use of synthetic keyboard sounds and rendering vocals, successful combination of elements such as HOUSE, ROCK and TECHNO, and the rhythm kept at 100 ~ 140 BPM.

Deep house style

A branch of HOUSE that features meaningful lyrics, soul songs and piano covers.

roar

Disco dance, usually refers to all-night disco dance, is also the most fashionable and underground form of youth entertainment in Europe, America, Japan and even Hong Kong and Taiwan. All music played in RAVE can be called RAVE (excluding music played by people who don't understand the meaning of RAVE). RAVE's music includes TECHNO, jungle, TRANCE, drum & etc. Bass, TRIP, DEEPHOUSE, etc.

Acid JUZZ

It combines the old and new typical jazz styles and singing styles. It is the product of hip-hop rhythm and modern technology, and its key lies in integration. Its characteristics are: HIP-HOP and HOUSE rhythm of live instruments, soft and silky music processing, easy-flowing soul music energy and its maintenance at 80 ~ 126 BPM.

Progressives

This kind of music is too mechanized to be classified under the general house beat, but unlike TRANCE.
