This paper discusses the principle of the torque ripple of BLDCM with focuses on the theoretical analysis of the relationships between torque ripple and parameters of windings,motor speed and bus voltage,as well as 3-phase reverse electrodynamic potential during phase converting.

对永磁无刷直流电机的换相转矩脉动的产生机制进行了分析，主要从理论上探讨了换相引起的转矩脉动与电机绕组的参数、换相期间的三相反电动势、电机的运行速度及母线直流电压等之间的关系。

R. t routing changes is also studied, a transformation method for the calculation of sensitivity of sojourn time w. r. t routing changes is presented. The problem of calculating the performance sensitivity w. r. t buffer siaes in general queueing networks is also solved by using finite event time perturbation analysis.

对计算性能指标对路径概率灵敏性的转换法也进行了研究，提出了一种计算逗留时间对路径概率灵敏性的转换法，本文还应用事件时间摄动的有限摄动分析解决了一般排队网络的性能指标对缓冲器容量灵敏性的计算问题。

But, I will tell you, Paul: In your almost total immobilization, the visibility and tangibility of you is a bundle of infinite activity-zillions of atoms, you might say-of energy pattern being fully energized, and there is nothing sluggish about it whatsoever.

但我要告诉你，保罗，在你几乎完全不动的情况下，你有形可见的存在正以最饱合状态的能量形式（套用你们的话则是亿兆的原子）运作著，没有任何一个部分是停滞不动的。

In contrast to the situation for a homogeneous isotropic neo-Hookean sphere, it is shown that not only there exists a secondary turning bifurcation point on the cavitated bifurcation solution which bifurcates locally to the left from trivial solution, and also the critical load is smaller than that for the material with no perturbations, as the parameters belong to some regions.

与均匀各向同性的neo-Hookean球体的情况相比，证明了当摄动参数属于某些区域时，从平凡解局部向左分岔的空穴分岔解上存在一个二次转向分岔点，空穴生成时的临界载荷会比无摄动的材料的临界载荷小。

Base on the above analysis and empirical study draw the conclusion, the cause of the inconsistence between the stock market and the economic growth in China and the suggestion about eliminating the inconsistence between them to improve economic growth are all present.

文章的最后，在分析和实证研究得出结论的基础上，分析了我国股票市场与经济增长之间产生异动的原因，并找出消解这种异动的对策，从而发挥股票市场的作用促进经济增长。

Different lops will vary in how they are capable of moving their ears, and may therefore be able to use only certain of the ear signals described here.

垂的程度不同，动的程度也不同，并且可能动的只有那么几下，这里会讲到的，但只要你尽量仔细观察你也能观察到跟竖耳兔差不多的耳动情况。

Combined with present situation on overcurrent protection of low voltage electrified wire netting in mine,analysed several reasons on appeared mis-start or refuse-start of overcurrent protection in mine,thus provided some concrete arguments for research workers and users of overcurrent protection .

结合目前井下低压电网过流保护的现状，探讨了井下过流保护出现误动与拒动的诸多原因，以便给采用新原理的过流保护的研究者和改进现有过流保护的使用者提供一些具体的论据。

The results showed that compared to participants of other three groups, neglect patients produced significantly more errors, longer reaction time, and greater number of saccades. They started their search to the left or right of the middle and employed inefficient search strategies. In particular, neglect patients performed worst when the target appeared on the far-left visual field.

实验结果发现，除跳跃眼动的平均长度外，忽略症病患的各项表现皆显著较差：他们均容易忽略患侧空间的目标物；即使可以侦测到，其反应时间和跳跃眼动的数目皆显著增加，主要从近端的两个区域开始扫描，且无法采取较一致且有效的策略来侦测目标物。

This paper introduces the control principle of the direct torque control system of an asynchronous motor, and proposes a new strategy to solve the problem of the large torque ripple and current ripple. The Matlab 6.5 simulation shows that it can solve the problem efficiently.

本文介绍了直接转矩控制系统的控制原理，并针对基于直接转矩控制的异步电动机运行时存在较大的电流及转矩脉动问题，提出一种新的控制方案，并基于Matlab 6.5对这种新方法进行仿真，仿真结果表明该方案能有效的解决电流及转矩脉动的问题。

The result shows that air temperature variation at the peninsular can be a good reflection of the Antarctic sea ice oscillations, which means a negative correlation between air temperature and sea ice anomaly near Antarctic Peninsular; a positive correlation between air temperature of Antarctic Peninsular and the sea ice anomaly at Ross Sea.

结果表明，南极半岛地区的气温变化可以反映南极海冰涛动的变化特征：气温距平和南极半岛附近海冰距平存在密切的负相关，和罗斯海外围区域的海冰距平存在正相关关系，能够较好地反映出南极半岛气温与南极海冰涛动以及ENSO之间的紧密联系。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
