Through a more detailed account of the submarine rescue equipment of the main countries, the authors believe that the US submarine rescue diving and recompression system and new NATO submarine rescue system are the most advanced in the world, and there is no significant technical development in the next period because these systems can well meet the submarine rescue needs.

文中比较详细地介绍了主要潜艇国家的援潜救生装备，通过分析后作者们认为，技术最先进的当数美国的"新型潜艇救援潜水和再压缩系统"和欧洲的"北约新型潜艇救援系统"。而且在今后一段时间内，从技术上来说，不再会有很大的超越这两大系统的发展，因为这些系统已能较好地满足当前一段时期内潜艇援潜救生的需要。

The characteristics of the filter include that the parameter variation ranges are taken into account, and within the parameter variation range each maximum magnitude of the residual vibrations is set to be equal. Thus, if the system parameters vary in lager ranges, the filter is more robust and the residual vibrations can be affectively eliminated.

该滤波器的特点是考虑了系统参数的变化范围，系统残留振动的最大幅值在参数变化区间内相等，从而提高了时滞滤波器的鲁棒性，特别是当系统参数大范围变化时，时滞滤波器有更强的鲁棒性，能有效消除柔性系统的残留振动。

The vibro-impact systems are familiar with the non-smooth dynamic systems.The dynamics research of the vibro-impact systems not only is significant in theory but also has practical values in engineering.Firstly,using the Poincaré map method,we get an existent criterion of single impact period-n motion in a two-degree-of-freedom vibro-impact system with damper.It is shown that our conclusions are valid through the numerical simulations.Moreover,the satiability of periodic motions is studied and the correspon...

基于Poincaré映射的方法，通过解析的方法导出了一类具有阻尼的两自由度碰撞振动系统的单碰周期n次谐运动存在性判据，经过数值模拟验证了理论分析的正确性，并给出了分析其稳定性的判别公式，通过数值模拟，讨论系统的局部分岔与全局分岔，同时比较了系统参数变化对其周期运动的影响，发现在强阻尼、弱激励、小质量比、较大恢复系数下系统将会出现较多的有规律的周期碰撞。

而对于变幅系统和曲线滑道活对重自重平衡系统的设计，传统意义上单纯的通过建立数学模型进行优化的方式来进行设计，或者单纯的作图法来设计，在很多方面暴露出弊端，如优化得到的点离实际需要的太远，或者作图设计速度较慢等，正因为如此，有必要对变幅系统和曲线滑道活对重自重平衡系统的设计重新做出一种新的尝试。
