400 words of speech about Deng Jiaxian

Dear teachers and dear students:

Everyone knows that Oppenheimer is the "Father of the Atomic Bomb" of the United States, and Sakharov is the "Father of the Hydrogen Bomb" of the former Soviet Union. "Father", however, who is the founder of China's "two bombs"? He is my country's famous nuclear physicist Deng Jiaxian.

With great reverence, I followed the footsteps of his life one by one...

In 1950, nine days after receiving his doctorate in the United States, Grandpa Deng Jiaxian returned to Beijing after going through many hardships. He has made great contributions to China's physics research.

In 1958, Grandpa Deng Jiaxian said goodbye to his family and began a secret process of anonymity. Together with countless scientists who were willing to remain anonymous, they finally developed the atomic bomb and the hydrogen bomb.

For 28 years, Grandpa Deng Jiaxian has dedicated himself all the time, even sacrificing his own life for the sake of the motherland.

When an airdrop test failed, he rushed forward to take the broken atomic bomb fragments into his hands for inspection. He was exposed to severe nuclear radiation and his body became weaker day by day. He has no regrets about this.

On July 29, 1986, Grandpa Deng Jiaxian spent his last effort for our country's nuclear weapons cause, but his last words were "die without regrets."

Grandpa Deng Jiaxian used his wisdom and life to develop the "two bombs" and made immortal contributions. What he left behind was not only the atomic bomb and the hydrogen bomb, but also his dedication to science and his sincerity to the motherland. His spirit released huge "nuclear energy" in the hearts of the people, inspiring countless patriots to secretly fight for national defense without regrets.

I was very excited when I learned that Grandpa Deng Jiaxian was the dean of the Chinese Academy of Physics.

I am excited, I am from the Chinese Academy of Physics,

I am excited, I live in a science city known as the cradle of scientists,

I am excited, My relatives, like Grandpa Deng Jiaxian, are engaged in the country's nuclear weapons industry.

I have a dream to be a scientist and learn from Grandpa Deng Jiaxian. When I grow up, I will "form the cornerstone of national defense and become the backbone of the nation."

My speech is over, thank you all. Deng Jiaxian was born in Huaining County, Anhui Province in 1924 to a scholarly family. The following year, he followed his mother to Beijing and grew up next to his father, who was a philosophy professor at Tsinghua University and Peking University. He entered primary school at the age of 5 and laid a good foundation in Chinese and Western culture under the guidance of his father. In 1935, he was admitted to Chongde Middle School and became best friends with Yang Zhenning, who was two classes above him and his neighbor in Tsinghua University. Deng Jiaxian was deeply influenced by the patriotic national salvation movement on campus. After the fall of Peiping in 1937, he secretly participated in anti-Japanese gatherings. Under the arrangement of his father, he followed his eldest sister to Kunming, the rear area, and was admitted to the Department of Physics of Southwest Associated University in 1941. When the Anti-Japanese War was victorious in 1945, Deng Jiaxian graduated from the Southwest Associated University and joined the "Minqing", a peripheral organization of the Communist Party of China in Kunming, and devoted himself to the struggle for democracy and opposition to the KMT's dictatorship. The following year, he returned to Peking and was hired as an assistant professor in the Physics Department of Peking University. He also served as the chairman of the Peking University Faculty and Staff Union during the student movement. With the ambition of learning more skills to build New China, he passed the postgraduate examination for the United States in 1947 and entered the graduate school of Purdue University in Indiana in the following autumn. Due to his outstanding academic performance, he completed his studies in less than two years and passed the defense of his doctoral thesis. He was only 26 years old at this time and was known as "Dr. Doll". In August 1950, nine days after Deng Jiaxian obtained his doctorate in the United States, he declined the invitations of his mentor and school friends to stay, and decided to return to China. In October of the same year, Deng Jiaxian came to the Institute of Modern Physics, Chinese Academy of Sciences as a researcher. In the next eight years, he conducted research on China's nuclear theory. In 1953, he married Xu Luxi, the eldest daughter of Xu Deheng, an important student leader of the May Fourth Movement and later vice chairman of the Standing Committee of the National People's Congress. In 1954, Deng Jiaxian joined the Communist Party of China. In the autumn of 1958, Qian Sanqiang, deputy minister of the Second Ministry of Machinery, approached Deng Jiaxian and said, "The country is going to set off a 'big firecracker'" and asked him if he was willing to participate in this work, which must be kept strictly confidential.

Deng Jiaxian agreed without hesitation. When he returned home, he only told his wife that he "had to change his job." He could no longer take care of his family and children, and communication was also difficult. The wife, who has been influenced by patriotism since childhood, understands that her husband must be engaged in work of great significance to the country and expresses her firm support. Since then, Deng Jiaxian's name has disappeared from publications and external contacts, and his figure has only appeared in strictly guarded courtyards and the Gobi Desert. After Deng Jiaxian took office as the director of the Theory Department of the Ninth Research Institute of the Second Ministry of Machinery, he first selected a group of college students to prepare relevant Russian materials and atomic bomb models. In June 1959, the Soviet government terminated the original agreement, and the Central Committee of the Communist Party of China determined to take matters into its own hands and develop atomic bombs, hydrogen bombs, and artificial satellites. After Deng Jiaxian became the person in charge of the theoretical design of the atomic bomb, he arranged for his colleagues to study calculations separately, and he also took the lead in tackling key problems. When encountering a figure about the atmospheric pressure of a nuclear explosion left by a Soviet expert, Deng Jiaxian, with the help of Zhou Guangzhao, overturned the original conclusion with rigorous calculations, thus solving a key problem related to the success or failure of China's atomic bomb test. Mathematician Hua Luogeng later said that this was the result of "a collection of the world's most difficult mathematical problems." Deng Jiaxian not only worked hard in secret scientific research institutes, but also often went to desert testing sites where sand and rocks were flying. In October 1964, it was he who finalized the design of the first atomic bomb that China successfully exploded. He also led researchers to quickly enter the explosion site to take samples after the test to confirm the effect. He also invested in research on hydrogen bombs with Yu Min and others. According to the "Deng-Yu Plan", a hydrogen bomb was finally made, and the test was successful two years and eight months after the atomic bomb exploded. This is the fastest speed in the world, compared with the 8 years it took France, the 7 years it took the United States, and the 4 years it took the Soviet Union. In 1972, Deng Jiaxian served as deputy director of the Institute of Nuclear Weapons, and in 1979 he was appointed director. In 1984, he directed the successful test of China's second-generation new nuclear weapons deep in the desert. The following year, his cancer spread beyond repair, and his request on National Day was to see Tiananmen Square. On July 16, 1986, the State Council awarded him the National "May 1st" Labor Medal. On July 29 of the same year, Deng Jiaxian passed away. The words he left before his death were still about how to work hard in cutting-edge weapons, and he warned: "Don't let people leave us too far behind..." Although Deng Jiaxian has been the leader of nuclear testing for a long time, he is extremely responsible for his work. , appearing on the front line at the most critical and dangerous time. For example, during dangerous moments where life and death depended on nuclear weapons detonators and uranium ball processing, he stood beside the operators, which not only strengthened management but also provided great encouragement to the operators. Once, a parachute accident occurred during an aerial drop test, and the atomic bomb fell to the ground and broke. Deng Jiaxian was well aware of the danger, but he rushed forward alone to take the broken atomic bomb fragments and examine them carefully. His wife, a professor of medicine, knew that he had "held" the broken atomic bomb, and when Deng Jiaxian returned to Beijing, she forcibly took him for examination. It was found that there was radioactive material in his urine, his liver was damaged, and radioactive material had invaded his bone marrow. Later, Deng Jiaxian still insisted on returning to the nuclear test base. When he was struggling, he insisted on installing the detonator himself, and for the first time gave an order to the people around him with the authority of the dean: "You are still young, you can't go!" In 1985, Deng Jiaxian finally left Lop Nur and returned to Beijing, still Want to attend a meeting. Doctors forced him to hospital and informed him that he had cancer. He fell weakly on the hospital bed, facing the comfort of his wife and Defense Minister Zhang Aiping, and said calmly: "I knew this day would come, but I didn't expect it to come so fast." The central government tried its best, but could not save it. his life. Shortly before Deng Jiaxian's death, the organization equipped him with a special car. With the support of his family, he just sat in and turned around in a small circle, showing that he had enjoyed the treatment provided by the country. Thirteen years after his death, on the eve of the 50th anniversary of the National Day in 1999, the Party Central Committee, the State Council and the Central Military Commission posthumously awarded the gold "Two Bombs and One Satellite Meritorious Service Medal" to Deng Jiaxian. Dear teacher, dear classmates:

; ; ; ; Hello.

You must have seen the beautiful rivers and mountains of the motherland. The surging river, the rolling Yellow River, and the continuous mountain peaks all belong to our great motherland.

The mountains and rivers of the motherland are majestic, the rivers of the motherland are graceful, and the mind of the motherland is extremely broad.

We are all descendants of Yan and Huang, descendants of the dragon. Our happiness comes from the motherland. Only when the country is rich and powerful can the flower of our happy life shine forever. Chinese history tells us that without a motherland, there is no home. If a country is not strong, it will be beaten. What we are closest to are our parents, and what we love most is China

When the iron hoofs of the invaders trample on our beautiful mountains and rivers, every Chinese with conscience has tears on his face and blood in his heart. The sacred and inviolable motherland, they groped in the darkness and fought in humiliation.

Wen Yiduo rose up to shoot the murder, and raised his eyebrows coldly at the assassin's pistol. Ji Hongchang hung up a wooden sign with the slogan "I am Chinese" and walked among a crowd of foreigners with blue eyes and yellow hair. among. Zhang Xueliang and General Yang Hucheng resolutely launched the Xi'an Incident in order to save the nation from peril...

It is these thousands of innocent children who hold up the backbone of our nation and the hope of the motherland; it is they, On my own "today", I used my heart and blood to compose the "March of the Volunteers" that is worthy of the times, so that our national anthem of the Republic of China and the People's Republic of China resounds throughout China today, so majestic, so majestic and loud

Shame and misfortune have become a thing of the past, and the Chinese nation has ushered in new glory. Since the reform and opening up more than 20 years ago, with the hard work of the working people, we have made great progress in military, science and technology, politics, and sports. At the just-concluded Athens Olympics, the athletes relied on their "ten years" "Sharpening the Sword" made China rank among the sports powers for the first time. The five-star red flag flew high over the Athens stadium again and again. The powerful and passionate national anthem of the Communist Party of China made countless Chinese people's hearts surge and tears filled their eyes.

Seeing the excited tears of veteran Wang Yifu after winning the gold medal, and seeing Liu Xiang crossing the finish line and running around the field with his hands raised, I remembered the scene of watching the Olympic Games when I was a child

That's a person On a summer evening, my mother and I sat in front of the TV to watch the opening ceremony of the Olympic Games. Seeing the national flags of different colors on the field, my mother asked me: "Xiao Can, which flag do you like best?" When I was six years old, She tilted her head and thought for a moment, then said, "Five-star red flag." "Why?" "Because it has the brightest color and the yellow five-pointed star on it is very beautiful." Mom said nothing, looked at me for a long time, and shook her head, "No , my child, because you are Chinese!”

“You are Chinese!” These five simple words speak volumes about the aspirations of so many Chinese people. It is precisely because of this. With a Chinese heart, the revolutionary martyrs shed their lives and blood, and the Olympic athletes fought bravely and achieved great success. When I was only six years old at the time, I would feel excited and excited when I saw the five-star red flag fluttering in the wind.

From that day on, I had this belief in my heart: the motherland is my mother, and the country is more important than the small family. When I grow up, I will build her stronger with my hands. The motherland has a vast territory, a glorious history, rich treasures all over the mountains and plains, and beautiful scenery of the three rivers and five mountains. The wild horse of thought is galloping, and I describe my motherland with my heart. Her long flowing hair is the thousands of rivers flowing leisurely, her strong and steep back is the continuous mountain peaks, and her bright eyes are the mountains. The water of Dongting, the waves of West Lake! In the sky of the motherland, "the bleak autumn wind is coming again today, it has changed the world"; in the land of the motherland, "the red rain makes waves as it pleases, and the green mountains turn into bridges deliberately". Looking at the thousands of miles of rivers and mountains of the motherland, it is like being in a room of poetry and painting.

The motherland is the pearl of the East, the soaring dragon of Asia, and the rising sun on the distant horizon. The motherland is in your heart, in my heart, and in the hearts of all of us. ; ; ; ; ; Thank you all.
