His life goal is to obey the needs of the country, but why did he refuse promotion twice?

Du Xiangwan, 83 years old this year

He is an academician of the Chinese Academy of Engineering and former vice president

Made great contributions to my country's hydrogen bomb test

Later, for national needs

Du Xiangwan switched from hydrogen bomb theory to laser research

He said his life's aspirations

Obeying the needs of the country

Du Xiangwan and his colleagues use a ruler

Calculated the principle of hydrogen bomb

October 16, 1964

my country's first atomic bomb exploded successfully

This year, Du Xiangwan returned to China after completing his studies in the Soviet Union.

Assigned to China Academy of Engineering Physics

With Deng Jiaxian, Zhou Guangzhao, Yu Min and others

Participate in the development of hydrogen bomb

The development of hydrogen bombs requires a lot of complex data calculations

At that time, China was quite short of relevant equipment.

Du Xiangwan and colleagues

With a slide rule in everyone's hand

After countless failures

Finally figured out the basic idea of ​​the hydrogen bomb principle

The correctness of the relevant models was verified

In 1967, my country's first hydrogen bomb was successfully detonated

Those hard but fulfilling years

It also became Du Lao's lifelong collection

To this day, he still keeps a

The slide rule used at that time

Treasure in his memory

And my former comrades

"Before Deng Jiaxian received the mission and set out

Say to my wife

'This is very important

It's worth dying for.'

At that time, everyone wanted to sacrifice themselves for the country.”

To concentrate on scientific research

He refused leadership promotion twice

For national security

Soon after completing the mission

Mr. Du switched from hydrogen bomb theory to laser research

In the 1980s

my country does not know much about the new field of laser

Foreign research on the application of lasers has also failed repeatedly

But Du Xiangwan and his colleagues identified the weak link

Overcoming difficulties step by step

Due to outstanding achievements

The leader tried to promote Du Xiangwan twice

Taking on leadership positions

But in order to devote more energy to scientific research

He turned down the promotion twice.

In 1991, Du Xiangwan served as the director of the National "863 Program"

Chief Scientist of Laser Expert Group

Decades later, laser manufacturing

It has become an important part of a technological power

It also enters the medical and other livelihood fields to benefit the people

Father's love for his country

It has always influenced him

Du Xiangwan's father Du Mengmo

He joined the Communist Party of China as early as 1926.

Served as Party branch secretary of Peking University

Head of the CPC Beijing Dongcheng District Committee

Organized a series of revolutionary activities

But until his death, he never told his son

Talked about the contributions he had made to the Party

Later, Du Xiangwan found a book

I just learned about my father's past.

My father always supported me

Du Xiangwan devotes himself to scientific research and serves the motherland

“At that time, he knew that I was studying nuclear physics.

China needs to know this direction.”

Du Xiangwan said that his father's love for his country

Has always deeply influenced myself

“The mission of our generation is different from that of the previous generation.

But we must take on the mission

For the country and for the family"

Salute to the patriotism!
