The system configuration and flight process are presented in this paper, as well as the analysis of mission characteristics, the key technologies and the technical advancement during the R＆D progress. The significance of circumlunar return and reentry spacecraft is given at the end.展开更多

For over half a century,Chinese geotechnical investigation professionals witnessed continuous technical advances as they undertook independently almost all of China's large-scale construction projects. Based on projects that won the "National Outstanding Engineering Investigation" Gold Medal Awards since the year 2000,this paper discusses the achievements of geotechnical investigation in the context of comprehensive technical ability,project evaluation and analysis,hi-tech applications and engineering monitoring,and analyzes several factors that have hindered the industry's further development and alignment with international practice. Finally,some suggestions are given for future improvement.展开更多
