中文摘要：

对船舶液压推进技术进行论述,并对其发展过程以及现状进行总结,在此基础上探讨液压推进技术的前景以及研究方向.液压推进技术在我国发展比较缓慢,对其深入研究应集中于高效传动方案设计、元件智能化以及模块化、降低噪声、强化系统工况匹配性能等方面.随着对该技术研究的深入,液压推进技术将在军用船舶、民用作业船舶以及深潜器等领域发挥越来越重要的作用,并有望成为某些特种船舶的首选推进方式.

英文摘要：

Ship hydraulic propulsion technology is analyzed and,the development and research status of ship hydraulic propulsion technology is summarized,and the prospect and development trend of the technology is discussed.Results show that the development of hydraulic propulsion technology in china is slow,and the further research should be focused on such aspects as high efficiency dive system design,intelligent and modular components design,noise reduction and strengthening system operating conditions matching performance,etc.With the further study of the technology,hydraulic propulsion technology will play more and more important role in military ships,civil ships and submersible boats,and it is expected to be the first choice for some special ships.
