英文摘要：

The principles of water-jet propulsion and its match with the system was examined, the hi-efficiency implementa- tion related design issues, modern analysis methods and the conclusions involved, as well as the thrust calculations were dis- cussed in detail. The problems and potential of the turning off and reverse operation were briefly depicted.
