3. Etiquette: Etiquette refers to people's etiquette in communication activities, including etiquette in daily life and work. The specific requirements are as follows: (1) Stand upright, hold your chest and abdomen, keep your eyes straight, your mouth slightly closed, smile, your arms naturally droop or cross in front of you, put your right hand on your left hand, and keep the state of providing services to guests at any time. Don't put your hands on your hips. Don't put your bag in your hands. The toe separation is 45%-60%. Knees and heels should be close together. When a person stands, his feet should be shoulder width, and his body should not stagger. When he is tired, he can take a half step back or move his position, but his upper body should still be upright. He shouldn't stretch his feet forward or backward too much, or even stand wide against the wall. * Standard stance training method: 1, standing against the wall; 2. Stand on your back; 3. Stand on the top of the book.

(2) Standing posture requirements for some post personnel: a. Attention should be paid to the standing position of the greeter. In addition to the above requirements, the arms naturally droop, the heels are close together, and the toes are naturally separated (including the outside, just the length of the feet) with a smile. If guests come in and out, their feet can relax a little. When guests arrive, they should immediately return to normal posture, put their hands on both sides of their thighs and bend their fingers slightly. B, the waiter's upper body is straight, his feet are separated (the heel separation distance is less than 8CM), and his arms naturally droop. Both men and women can use the back hand posture (back posture), gently hold their hands behind their backs, or put their hands on their small abdomen (front abdomen posture). C, receptionist upper body straight feet apart, the arm can be properly handled, but can't hold the arm (front abdomen).

Four. Walking posture: Walk lightly and steadily, and pay attention to holding your head up and chest out, abdomen in, shoulders flat, and body straight. When a woman walks in one step (you can't take big steps with her feet), when a man walks, his feet follow two lines, but the two lines are as close as possible, and his steps can be a little bigger. The horizontal distance on the ground is about 3 cm, and his arm swings naturally with an amplitude of 30-40 cm. When he walks, so does the man. When you have to pass by a guest because of work needs, you should politely apologize and say you are sorry.

When three people walk together, the guest is in the middle, and the lady is allowed to walk on the sidewalk.

2. Basic knowledge of musical instruments `` Who knows?

At least 0.27 yuan to open a library member, check the complete content. Original publisher: pinky6 173 electrical instrument knowledge contest question bank 1, cable generalized wire and cable is also referred to as cable.

Cable in a narrow sense refers to insulated cable. It can be defined as a * * body consisting of the following parts, one or more insulated wire cores and their respective possible cladding layers, a total protective layer and an outer protective layer.

Cables may also have additional uninsulated conductors. ? Basic structure of wire and cable: conductor and insulator.

2. Currently? Generally speaking, the safe cross-sectional flow of copper conductor is 5-8A/ mm2, and that of aluminum conductor is 3-5A/ mm2. In a single-phase 220V line, the current per 1KW power is about 4-5A, while in a three-phase circuit with three-phase load balance, the current per 1KW power is about 2A.

That is to say, in a single-phase circuit, each 1mm2 copper conductor can bear the power load of 1KW; The three-phase balance circuit can bear 2-2.5KW power. However, the greater the working current of the cable, the smaller the safe current per square millimeter.

? The formula of allowable safe working current of cable is: 10 times five (less than 10 times five) 100 times two (more than 100 times two) 2 times 500 times three (2 times four, 3 times five times three) 7 times five times five (both lines of 7 times and 9 times five are multiplied by 2.5), and the temperature of pipe threading is 10% (multiplied by 0.8 or 0.9 on the calculated safe current as the temperature changes). Copper wire upgrade calculation (in the same section of aluminum) If the 2.5-point copper core wire is one level higher than the 2.5-point aluminum core wire, it will be calculated as 4 square millimeters of aluminum core wire) bare wire plus half (on the basis of the original calculation of safety current). 3. What are the common types of electric (wire) cables? Meaning of cable specification and model: In the wire model, the letter B stands for laying wire, the letter V stands for PVC in plastic, and the letter R stands for flexible wire (conductor is wound with many filaments). There are also symbols that omit copper core and hard wire (ordinary single-core conductor).

Common cable type: BV- indicates single copper core poly.

4. Ask students about gfd etiquette.

What are the ways of etiquette education for primary school students? 1. Personal etiquette includes gfd, etiquette, speech and dress.

From the perspective of gfd, the main requirements are cleanliness, and the face, neck and hands should be washed clean; Hair should be cut on time and washed frequently, and nails should be cut frequently; Pay attention to oral hygiene, brush your teeth in the morning and evening, rinse your mouth after meals, and don't chew gum in front of guests; Take a bath and change clothes frequently to eliminate body odor. If you have body odor, you should apply medicine or treat it as soon as possible. From the aspect of manners, it is mainly required from the aspects of standing, sitting, walking, demeanor and movements. The ancients once gave an image summary of people's posture: "Standing like a pine, walking like a breeze, sitting like a bell, lying like a bow."

Beautiful standing gives people a feeling of being tall and straight and spirit. The body is upright, the chest is lifted and the abdomen is closed, and the toes are slightly V-shaped. No slouching, neck control, shrugging and collapse; Don't cross your hips or hands on formal occasions; Sit upright, don't be stiff, don't lie and sit. The distance between legs should be shoulder width, and hands should not be separated. You should naturally put your hands on your knees or handrails, which is generous and decent. When walking, you need to hold your chest out, swing your shoulders and arms naturally, and walk at a moderate speed to avoid splayed feet, shaking or squeezing your feet; Expressions and manners require showing respect, understanding and kindness to people, smiling naturally, and avoiding bad behavior habits, such as picking teeth, picking ears, picking nose, scratching and pinching feet.

In terms of conversation, we should be sincere and kind, use civilized language, be concise and decent, and not be silent or chatter endlessly. We should listen to each other carefully and avoid looking around and looking at other things during the conversation. There are many people talking, so don't just talk to one person and ignore others.

From the dress point of view, it is required to be clean, tidy and fit, and wrinkles are prohibited. 2. Public etiquette * * * Public etiquette includes walking, asking for directions, taking a bus, shopping and watching a play in a theater.

In addition to paying attention to posture and posture, you should also abide by traffic rules, greet and greet acquaintances, and you should not turn a blind eye; If you need to talk to an acquaintance, you should pull over or talk in the corner. You shouldn't stand in the middle of the road or in crowded places. Pedestrians give way to each other, young people give way to the elderly, and healthy people give way to the disabled. When asking someone the way, first say hello with polite expressions, such as "I'm sorry to bother you" and "I'm sorry". Young people should choose proper names when asking for directions, such as "grandpa", "aunt" and "uncle" before asking for directions. After listening to the answer, be sure to say, "Thank you!" "If you are asked by a stranger, you should answer carefully. If you don't know, you should say, "Excuse me, ask someone else. "

When shopping in the store, don't pretend to be "God", but use polite language and avoid using words such as "Hello" and "Cough". You should also say "thank you" after shopping. In the theater, you can't talk loudly, and you can't litter and peel. Try to arrive and take your seat as early as possible; If you are late, you should walk low and fast; When watching live performances, we should respect the actors and applaud politely when appropriate. When the actor takes a curtain call, he can't leave early.

By bus, bus and train, people are crowded, so we should take care of the elderly, children and the disabled; Collision between people, don't call names, understand and tolerate; Keep the car clean and don't throw things around; Students should not grab seats when they get on the bus. 3. hospitality and guest etiquette when guests come from home, they should make preparations in advance and tidy up the room.

Primary and middle school students should also learn to entertain guests as hosts. Welcome the guests into the house, help them get dressed, and ask them to sit down in the right place.

Ask the guests what to drink and offer it to them. It is necessary to display and receive objects with both hands.

Take the initiative to talk to the guests generously. Guests should be polite when they leave, saying "please sit down for a while" and "have another cup of tea".

See the guests off at a distance, say "goodbye" and "welcome again" When visiting relatives and friends, be neat and clean, and bring as many small gifts as possible to show respect for the host.

In the home of relatives and friends, you can't speak loudly, but you should speak politely. Don't use the things in the owner's house without the owner's permission. Even close relatives and friends should say hello first and get the master's consent.

If you eat in the host's house, you should pay attention to the etiquette when eating: you can't sit down first, you can't touch the food first; Please sit down before you move chopsticks, and don't put your elbows on the table. After dinner, sit down with you for a while, or say, "I'm finished, please take your time." Then leave your seat and go to another room to rest.

When you say goodbye, you should say thank you, such as "I am very happy today" and "Welcome to my home". These are some basic etiquette in life.

Etiquette is manifested in life. As long as teachers pay more attention to daily education and teaching, set an example, correct it in time, and gradually make students develop the habit of civilized manners, then our student ID card will certainly become a modern civilized person with temperament, grace and education. How to conduct civilized etiquette education among primary school students should pay attention to the following points.

1, fine, that is, the requirements of civilized etiquette education should be refined. To carry out civilized etiquette education, students should first make clear the requirements of civilized etiquette convention, which is an important first step to carry out civilized etiquette education.

Because primary school students are young and have poor cognitive and understanding abilities, abstract thinking has not been fully developed. Therefore, the requirements for them should be clear, specific and detailed, and the enforceability of the requirements should be improved. For example, there are specific requirements for students' civilized etiquette during recess: after class, students on duty are responsible for cleaning the blackboard and tidying up the classroom, while other students go outside the classroom to see the greening or do outdoor activities.

Speak and behave in a civilized way. Use polite expressions: please, you, hello, thank you, sorry, never mind, goodbye; Use good body language: smile, bow, shake hands, wave, clap and salute correctly.

These requirements are very detailed and specific, which is helpful for students to follow and teachers to test students' implementation. 2. Suitability, that is, the civilized etiquette requirements for specific students must be adapted to the specific situation of students.

Education should follow the principle of teaching students in accordance with their aptitude, and so should the education of civilization and etiquette. Teachers should help students make stage goals and plans according to their weak links, and the goals should be achieved by students through certain efforts, that is, "jumping up and reaching."

"Goals that are too difficult to achieve will make students feel afraid and bound.

5. Learn electrical instruments and measurement knowledge.

First, associative memory method For pointer instruments, the measuring mechanism is its core; For digital instruments, the digital basic table is its core.

Through the radial correlation of measuring mechanism, we can see the basic situation of the instrument at a glance. Such as indicating instrument core → measuring mechanism → five-part device → four series instruments → structure, principle, technical characteristics, precautions in use, representative objects, etc.

That is, the measuring mechanism is led out from the indicator core, which is divided into five parts according to the different functions of its components. Three of these five devices are torque devices, which are related to the structural characteristics of four series of instruments through the characteristics and components of three torques, and then to various instruments.

Such as: magnetoelectric ammeter, voltmeter, electromagnetic ammeter and voltmeter, watt-hour meter, voltmeter, ammeter, frequency meter, phase meter, induction watt-hour meter, etc. In addition, it is equipped with multimeter with magnetoelectric system as measuring mechanism, transformer clamp ammeter, megohmmeter with magnetoelectric system ratio meter as measuring mechanism, one-arm bridge with magnetoelectric system as galvanometer, clamp ammeter with electromagnetic system as measuring mechanism, etc.

Second, the formula memory method 1, "short voltage open current, 150 amp" is convenient for you to remember the correct usage and rating of the transformer. The simple eight words have two meanings. One is that short circuit is prohibited on the secondary side of voltage transformer with rated voltage of 100V, and open circuit is prohibited on the secondary side of current transformer with rated current of 5A. The second is that the secondary side of the voltage transformer works in an open circuit state and can be connected with a fuse, while the secondary side of the current transformer works in a short circuit state and cannot be connected with a fuse.

2. "The internal cause is basic, and the external cause is additional", and eight words summarize the reasons for basic errors and additional errors. In other words, the errors caused by internal factors are basic errors, such as friction in the moving parts of the instrument and improper assembly of the instrument parts; Errors caused by external factors are additional errors, such as the interference of external magnetic field or electric field around the instrument, the sudden change of temperature, the instrument not being placed in the normal position, etc.

3. The word "left force and right sense" is convenient for you to remember and master the application of the left-hand rule in analyzing the working principles of various instruments, that is, the left-hand rule is used to determine the force and the right-hand rule is used to determine the induced current. 4. The application of single-arm bridge is summarized as follows: "Megaohm is large, double bridge is small, and single bridge is needed for measurement", "Among the bridge arms, it is better than the arm; The more "-"decreases, the more "+"increases; All four gears are used and the bridge is balanced.

These formulas summarize the precautions and selection principles of the bridge, that is, megohmmeter is used to measure large resistance, double-arm bridge is used to measure small resistance accurately, and single-arm bridge is used to measure medium resistance; When using a bridge, it is very important to choose the resistance of the comparison arm. When the galvanometer pointer deflects in the "+"direction, the resistance of the comparison arm should increase, otherwise, the resistance of the comparison arm should decrease. Only when all four gears of the comparison arm (used for one-arm bridge) are used can the bridge be truly balanced. .

6. What are the indicator lights on the car instrument?

Learning Tips: The indicator light on the automobile instrument is also called the instrument light, and its functions can be divided into three types: the first is the display function, such as the turn indicator light, the far and near light, and the small light indicator light. , and the general light color is blue or green; The second is the function of reminding the driver, such as brake pad wear, fuel lower limit indication, engine fault indication and so on. This light is generally yellow to remind the driver to deal with it as soon as possible; The third is the warning light, which is mainly used to give a warning when the vehicle fails or is abnormal.

The indicators on the automobile instrument include fault indicator, charging indicator, oil pressure indicator and coolant temperature indicator, as shown in figure 10-2. Learning tips: ① Oil pressure indicator: This indicator is used to display the pressure of oil in the engine.

Turn on the ignition switch. When the vehicle is self-checking, the indicator light should light up and go out after starting. ② Coolant temperature indicator lamp: This indicator lamp mainly displays the temperature of the coolant in the engine, and it only lights up for a few seconds during the vehicle self-test, and usually goes out.

③ Brake disc indicator light: the indicator light is "!" Circle. Or the letter "p", which is usually closed. When the parking brake is pulled, the indicator light will light up automatically.

(4)④ABS indicator: The indicator lights up for about 3? It is normal to go out after 4 s. No light or constant light indicates a fault. You can continue to drive at a low speed, but you should avoid emergency braking.

⑤ Safety gas sign indicator: This indicator mainly displays the working status of the safety gas sign. After turning on the ignition switch, about 3? 4s, not lit or always lit indicates that the system is faulty.

7. What are their roles?

Automobile instrument is a device used to monitor the working condition of automobile system.

Instruments commonly used in automobiles include oil pressure gauge, coolant thermometer, fuel gauge, speedometer, tachometer and odometer. With the development of automotive electronic technology, multifunctional, high-precision, high-sensitivity and intuitive electronic digital display and image display instruments are constantly applied to automobiles.

The function of automobile instrument is not only simple display, but also various working conditions of automobile can be controlled by monitoring the parameters of automobile parts and processing them by microcomputer. 1) The oil pressure gauge is used to indicate the oil pressure when the engine is running and whether the engine lubrication system works normally. Commonly used oil pressure gauges are electromagnetic, electrothermal and spring tube.

2) The coolant thermometer is used to indicate the engine coolant temperature. 3) The fuel gauge is used to indicate how much fuel is left in the fuel tank.

4) The speedometer is used to display the speed. 5) The tachometer is used to display the engine speed.

6) The odometer is used to indicate the cumulative mileage of the car.
