Former director of Dalian Institute of Chemical Physics, Chinese Academy of Sciences
Famous Physical Chemist
The founder and pioneer of the field of high-energy chemical laser in mainland China
One of the founders of the discipline of molecular reaction kinetics
Winner of the highest national science and technology award
Comrade Zhang Cunhao, senior academician of the Chinese Academy of Sciences
Ineffective medical treatment due to illness
He passed away at 13:08 on July 12
He was 96 years old
Early years of the establishment of New China
Zhang Cunhao returned to the motherland against all odds
throughout his life to meet the needs of the country
He has changed the direction of scientific research many times
He dedicated his life to the cause of science and technology in his homeland
Zhang Cunhao was born in a scholarly family in Tianjin
1948
20-year-old Zhang Cunhao stepped out of the country to study in the United States
When he just gained
M.S. in Chemical Engineering from the University of Michigan
The Korean War broke out
Zhang Cunhao resolutely gave up
Excellent scientific research conditions and high-paying jobs abroad
Returning to my homeland, where conditions were still very difficult at that time

After returning to the motherland
Zhang Cunhao came to Dalian Institute of Chemical Physics
officially began his scientific research life to serve the motherland
Early 50s of the 20th century
The continent's oil supply is in short supply
It is also facing a total blockade by Western countries
In order to solve the urgent needs of the country
Zhang Cunhao and his collaborators developed it in a short period of time
Water gas is synthesized as a liquid fuel
High-efficiency molten iron catalyst
Zhang Cunhao (first from left) conducts experiments on the synthesis of liquid fuels from water and gas in the laboratory
Late 50s of the 20th century
In a tense international situation
Zhang Cunhao turned to the field of rocket propellants
He and collaborators
Regardless of toxicity and explosion hazards, a large number of experiments
Finally proposed
Multi-layer flame theory of solid propellant ignition rate
In 1960, the world's first station
After the advent of the ruby laser
Lasers have become an international research hotspot
For the needs of the national strategy
Zhang Cunhao "changed careers" again
Together with a large group of young and middle-aged scientists
Started to develop chemical lasers
1985
The team developed it for the first time in the world
Discharge-initiated pulsed oxygen-iodine chemical laser
In 1992, the team developed
The first continuous-wave oxygen-iodine chemical laser in China
In order to promote the rapid development of the field of chemical lasers in Continental
played a vital role
Zhang Cunhao recalled his scientific research career, and in the past few decades, his scientific research has experienced three "career changes", and there is always a light in his heart that is pulling him, and that light is the needs of the country
Every time he "changed careers", he tried his best to be perfect
In 2014, Zhang Cunhao won the 2013 National Science and Technology Award, he said, since his youth, his biggest dream in scientific research life is to serve the country
"The needs of the country are the direction of my research!"
Remembrance, salute!
