To control the exciting winding current and to produce rounded and even inner complex magnet field.

该控制方法能使步进电机低频振荡和噪声有所减轻、高频不失步，并且在运行的过程中细分切换不产生速度突变。

For a single filter, the center frequency is 39.5MHz, the 20dB shape factor is 2.8, and a bandwidth is 49 kHz,respectively.

除此之外，吾人另制作高频单一滤波器的中心频率值39.5 MHz，波形常数为2.8，频宽为49kHz。

Sixth, Using the ability of the better keeping the image's detail of the morphological filter with omnidirectional multiple structuring elements and the ability of the strong removing noise of the improved center weighted median filter, this dissertation suggests a new kind of designing project of the hybrid filter for de-noising of pulse noise, which applied the idea of the stack filter based on omnidirectional structural elements constrains to the project.

利用全方位形态滤波的图像细节保持性能，中心加权中值滤波的噪声抑止能力和全方位结构元层叠滤波方案的并行处理思想，设计了一种新的脉冲噪声混合滤波新方案，它在滤除噪声的同时较好地保持了图像的细节部分，特别是其高频微小细节部分。

Therefore, even if the filter of the same circuit, because of the characteristics of different devices installed in different ways, the internal structure of the different, and their high-frequency performance will be a lot worse.

因此，即使滤波器的电路结构完全相同，由于器件的特性不同、器件的安装方式的不同、内部结构的不同，它们的高频性能会差很多。

On the aspect of error compensation, the system using the geometric average sound pressure instead of the arithmetic average sound pressure to get the sound pressure of the measurement point. This method not only reduces the high frequency error in the sound intensity measurement, which compensates the finite difference approximation error, but also greatly reduces the computation of the sound pressure spectrum.

误差补偿方面，课题采用几何平均声压代替通常的算术平均声压来计算双传声器法的声场声压值，这样不仅可以有效的减少声强测量中的高频误差，对有限差分误差起到了补偿作用，而且还大大减小了声压谱计算中的计算量。

The wavelet function is very suitable for solving the boundary value problem of ODE,not only for it characteristic of finite basis function,but has advantage of frequency method.

由于小波函数既有有限元基函数的特征，又有频域方法的优点，加之对高频信号的聚焦能力，非常适合求解微分方程边值问题。

Based on Kane's dynamics theory of multiple rigid body, the firing dynamic model was established for the coupling system of firer and rifle, and dynamic numerical simulation of the system was carried out. The launching motion parameters of equivalent bodies of firer and rifle were obtained.

基于凯恩多刚体动力学理论，建立了射手与步枪系统的发射动力学模型，进行了高频点射步枪人机耦合系统发射动力学的数值仿真，得到了射手及步枪等效体在发射过程中的运动参数。

On one hand, it overcomes Fourier Transform that is not equal to analyzing unsteady signal and transient signal; On the other hand, it overcomes Fourier Transform that the scale of window of time domain and frequency domain is fixedness.

因此，本文通过运用小波分析对这些特征信息进行分析提取，结果表明利用暂态过程中含有的高频信息，能够有效实现故障选线。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
