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。

Convention V-belt Continuously Variable Transmission, shifts gears the travel mechanism property fixed constraint, unable full into full play initiative control advantage, to engine and Transmission on the go to hold optimum match, Also takes into consideration acceleration and fuel consumption performance, so this paper research Motorcycles with an Electronically-Controlled Continuously Variable Transmission shift gears planning, to use motor power screw, we shall revolve motion changes rectilinear motion, to push driving sheaves achieved to change speed ratio; Comparison between analysis convention CVT speed ratio shift gears curves of acceleration and fuel consumption performance optimum curves, use engine can hold high performance output or low fuel consumption region run.

中文摘要传统皮带式无段变速器(Continuously Variable Transmission， CVT)，换档行程由於机械特性的限制，无法完全发挥主动控制的优点，让引擎与变速器随时保持在最佳的匹配状态，同时顾及加速性能与燃油消耗，所以本文主要研究机车用电子控制式无段变速系统(Electronically Controlled Continuously Variable Transmission， ECVT)最佳换档规划，利用马达与动力螺杆，将旋转运动改变为直线运动，以推动主动滑轮达到改变减速比；分析传统CVT减速比换档曲线与最佳化曲线之加速性能及燃油消耗比较，使引擎能够保持较高性能输出或较低油耗区间运转。

I was like a pianist studying a piece of music, phrase by phrase, rehearing it, trying to discover and recreate exactly what the composer was trying to convey.
