通过力学性能及轮胎有限元分析计算，认为必须改进传统设计使筒体的转动方向与传动装置反向，这样可以在非传动侧均匀设置支撑，以减少主动侧、被动侧的支反力，即减少轮胎的弹性变形阻力矩，达到保护减速机的目的

Calculating results show that variation of the propellant inlet pressure makes little impact on engine performance parameters, and the engine will transit to a new stable state. The parameter transition curves are smooth. When the engine thrust is adjusted in a small range within a short period, the parameter transition curves are also reposeful. But when the adjusting range becomes large, the parameter transition curves will fluctuate acutely. Thus, when large range adjusting is required, the time of adjusting should be lengthened or the adjusting should be divided into adequate steps.

计算结果表明，当发动机在某一个稳定工况工作时，发动机入口推进剂压强的变化对发动机性能参数的影响不大，发动机的参数都能比较平稳的过渡到一个新的稳定工况；当发动机在短时间内进行小范围的推力调节时，发动机参数的过渡过程的曲线也比较平稳，但是当在短时间内进行大范围推力调节时，参数的过渡过程的曲线振动比较剧烈，因此应当在进行大范围推力调节时，应当对调节时间进行适当延长，或者分级进行推力调节。

The development of the index have catched up with the development of the economy and the society.We can ameliorate our index in many ways. We can fetch in new index,such as rewarding index of investment capital, it can be used to avoid the ruleless fluctuate caused by unregular revenue. We can fetch in the accrual ability of immateriality assets and "social responsibility" to enhance the deal of non-currency info and knewledge assets info. We can fetch in the method of key index analyse through relevancy analyse to conform the sequence of significance.

我们可以从多方面对指标进行改进，可以通过引进新指标如投资资本报酬率来克服因非经常性收益使企业业绩出现忽高忽低地波动的问题；可以通过引入无形资产获利能力评价指标、"企业社会责任"的概念来加强企业非货币性信息、知识资产信息在评价体系中的份量；通过引进企业获利能力关键指标的灰色关联分析来科学地确定指标的重要性顺序，以减少指标使用的盲目性。

ABSTRACT:The half-power bandwidth method is the commonly used method at home and abroad, the authors discover that factors, such as the sampling frequency, the frequency resolution, the ratio of the sampling frequency to the signal frequency, the analyzed width and the damping ratio, make the estimated damping ratio fluctuate vastly. Mostly the result is incredible except for some conditions, the error is sometime amazing, which is not acceptable.

半功率带宽法是国内外常用的测试阻尼的方法，笔者发现半功率带宽法由于受到信号处理中的①采样频率SF②频率分辨率△f③采样频率与信号频率之比K ④采样分析的长度T和⑤阻尼比D的大小等因素的影响使得测得的阻尼比值波动很大，除少数状态是可信的外，多数状态是不稳定的，有时误差惊人，得到的测试数据不能使用，易导致错误的结论。

Currency substitution is the inevitable problem during the developing course of developing countries,which will make exchange rate fluctuate frequently、influence the independence of monetary policy、decrease government's inflation tax and seigniorage、slack social public's confidence in domestic currency , only to the stability of macro-economy and the effective power of economic policies.

货币替代是发展中国家在开放过程中所不可避免的问题，它的存在会使汇率频繁波动、影响货币政策独立性、削弱政府的通货膨胀税和铸币税、涣散社会公众对本币的信心等，这会严重影响国家宏观经济的稳定和经济政策的效力。
