Peng Xianghua, male, Han nationality, mass, junior high school education, born in Tongliang, Chongqing,1June 1969, deputy manager and senior engineer of Xingquan Railway Project Department of China Railway Second Bureau and Second Company.

20 15 Peng Xianghua participated in the construction of Lalin section of sichuan-tibet railway, and his bid section is the most difficult, with very complicated geology, fragile ecology and very high construction requirements.

There was a geological exploration, which required technicians to descend from a cliff 50 to 60 meters high along the rope, and at the foot was the choppy Yarlung Zangbo River. Many workers are reluctant to take this "hard job", but Peng Xianghua stepped forward and "danced" on the cliff alone, successfully finding the necessary information and laying a solid foundation for the success of blasting in the future.

2. Xu Liping

Xu Liping, male, born in 1968, is the head of the solid fuel powder molding group of aerospace engine in No.7416 Factory of the Fourth Research Institute of China Aerospace Science and Technology Corporation, a national senior technician and a special aerospace technician.

Since 1987 entered the factory, Xu Liping has been engaged in micro-shaping of missile solid fuel engine propellant. Solid fuel engine is the heart of strategic and tactical missile equipment and the key component for launching manned space rocket.

There are thousands of processes in its manufacture, among which the most demanding process is the micro-molding of engine solid fuel. Carving solid fuel, that is, gunpowder, is extremely dangerous. A careless spark can cause combustion or even explosion.

Powder molding is a difficult problem all over the world and cannot be completely replaced by machines. Cutting force depends entirely on the workers' own judgment. Powder forming is irreversible. Once you cut too much, or leave a knife mark, the accuracy of the powder surface will not match the design. After the engine is ignited, the powder cannot burn in the predetermined direction, and the engine is likely to deviate from the track or even explode.

0.5 mm is the maximum permissible error of solid motor powder surface accuracy, and the powder surface error of Li Xu's hand carving is less than 0.2 mm, which is perfect, which makes his masters far behind.

Male, born in 1979, Han nationality, Zhong * * * party member, vice monitor and senior technician of the electrified class of the transmission maintenance center of Shandong Electric Power Company of State Grid.

In the past 20 years, he has experienced live working 100 times, reduced the power outage time by more than 300 hours, and completed many major tasks such as anti-icing rescue, power supply during the Olympic Games and the National Games, power supply at the 18th National Congress, and line dancing prevention, saving electricity1000 million kWh for the society and avoiding economic losses of hundreds of millions of yuan.

4. Zhang Dongwei

Zhang Dongwei, born in 198 1 year 65438+February, has a college degree. He is now the leader and senior technician of the second group of enclosure system workshop of Hudong Zhonghua Shipbuilding (Group) Co., Ltd., mainly engaged in carbon dioxide welding and argon arc welding of LNG (liquefied natural gas) ship enclosure system.

LNG carrier is an internationally recognized "three high" ship with high technology, high difficulty and high added value. It is known as "the jewel in the crown of shipbuilding industry", and its construction technology is only mastered by a few shipyards in developed countries such as Europe, America, Japan and South Korea.

The development and construction of LNG carrier is a self-challenge of Hudong people in response to the call of the CPC Central Committee to realize the strategic goal of CSSC "531"and build China into the largest shipbuilding country in the world at an early date, which is of great significance to promoting and ensuring the implementation of the national energy strategy.

Zhang Dongwei was one of the first people to build LNG carriers in China. From the time he came into contact with LNG carriers, he was determined to contribute to the construction of LNG carriers in China.

During the construction process, Zhang Dongwei carried forward Hudong Zhonghua's enterprise spirit of "unity and hard work, striving for first class", was willing to endure hardships and be brave in dedication, and solved one problem after another with his own intelligence, making outstanding contributions to the smooth construction of LNG series ships.

Zhou, male, Professor Zhou, Director of Endoscopy Center of Zhongshan Hospital affiliated to Fudan University.

Traditional poetry surgery is easy to damage the esophagus of patients. Zhou found another way, and built an invisible tunnel in the interlayer of the patient's esophageal wall, which not only alleviated the pain of the patient, but also made China's minimally invasive resection technology of digestive endoscope lead the world.
