In recent years, China’s aerospace industry has made remarkable achievements, and liquid rocket engine technology has also been effectively developed. In this article, the development processes of China’s liquid rocket engines are discussed. Then, the performance features of China’s new generation liquid rocket engines as well as the flight tests of the new-generation launch vehicles are introduced. Finally, the development direction and the most recent progress of the next generation large-thrust liquid rocket engine is presented.展开更多

But with the further promotion of China's reform and opening-up and intensification of the further improvement degree, the main factors influencing a regional economic growth constantly change. This paper utilizes the relevant data of Sichuan to set up the econometric model and quantitatively studies the factors influencing economic growth of Sichuan. Through comparing the greatness that each factor influences the economic growth of Sichuan, the paper takes system changes as leading factor to influence the economic growth during 1984-2003 of Sichuan. At the same time, the upgrading of industrial structure will be a core of economic growth in the future, and the scientific and technological progress is the potential force of economic growth.展开更多
