China's first artificial satellite sounded "Dongfang Hong", which is behind his exploits

Zhang Dayu joined the party volunteer book by hand filling in the pages

He became seriously ill in 1987

I can't call my family's name anymore

A cold winter day

He was suddenly gone

When he was found, he was wearing only a thin sweater

Fingers frozen barely straight

He carried a 20-pound black leather bag full of books

Standing motionless

He said, who is more than 80 years old

I was waiting for the bus to work

China's first artificial satellite sounded "Dongfang Hong", which is behind his exploits

Zhang Dayu

He is a famous physical chemist - Zhang Dayu

One of the founders of catalytic science in China

China's first artificial satellite sounded "Dongfang Hong", which is behind his exploits

In 1960, Director Zhang Dayu (fourth from the left) led some experts to visit Daqing.

After graduating from Tsinghua University

He went to Germany to study

Return to China upon completion of school

He witnessed it

Compatriots were persecuted

The motherland was wantonly trampled upon

He aspired

Save the country with "industry" and "science"

He insisted on teaching in the midst of the flames

Run factories, build research institutes, and recruit talents

China's first artificial satellite sounded "Dongfang Hong", which is behind his exploits

He proposes research directions:

The country is most desperately needed

We are the most suitable

Catch up and aim accurately

He is determined to forge ahead

In 1957, Zhang Dayu (first from the right) and Zang Jingling worked next to the catalytic supersorption device.

During the War to Resist US Aggression and Aid Korea

The country is in urgent need of toluene, the raw material for explosives

He quickly led the development of new technologies for toluene production

In 1964

In order to meet the needs of fertilizer production

He took the lead in tackling the key technologies of catalyst development

In 1955, the Academic Committee of the Institute of Petroleum research of the Chinese Academy of Sciences was established, with Zhang Dayu (fourth from the right in the front row) as the director.

The first artificial satellite plays "Dongfang Hong"

Solid lubrication also plays a key role

Among them, there is his hard work

He has the lifeblood of the national economy

Face the cutting-edge challenges of defense

In 1958, Zhang Dayu and his son were at home in Songshan Street, Dalian.

His "surface bond theory"

Brilliant results have been achieved in the guidance practice

He established China's first oil and coal research base

He opened up new fields of chemical physics research in China

He laid the foundation for large-scale energy research in china

It filled many gaps in domestic chemical research at that time

In 1976, Zhang Dayu (left) had a cordial conversation with Miao Yuntai.

He always

Stand tall and see far

He brought out a large number of scientific research backbones

He was a strategic scientist of his time

His name is Zhang Dayu

He joined the Communist Party of China in 1960
