采用平面梁单元计算平面刚架的变形和内力,该函数定义了平面杆系的有限元模型数据(The plane beam element calculation plane frame deformation and internal forces, the function defines a finite element model of the data plane frame)

太阳同步卫星及其轨道计算，用于设计太阳同步轨道，并且给出一个实例，介绍卫星轨道参数的计算方法(Sun-synchronous satellites and their orbital calculations for the design of a sun-synchronous orbit, and an example is given, satellite orbit parameters calculation method)

In this paper the topology of a four-leg shunt active-power filter (APF) is given. The APF compensates harmonic and reactive power in a three-phase four-wire system.

实现wiener模型数字预失真，效果非常好，经过验证程序无任何错误。(To achieve the wiener model pre-distortion, the effect is very good, the program checked for any errors)

适用于雷达方面学习的初学者熟悉相关参数设置了解相关线性调频信号离散化，匹配滤波的产生方法等一系列基本问题。比较时域和频域不通滤波方法的区别(Beginners apply to radar aspects of learning to understand familiar with the parameters related to the chirp signal discrete, matched filtering to produce a series of basic questions like. Comparison of time domain and frequency domain filtering method fails difference)

以前下载的一些用matlab编写的关于运动轮廓模型程序(Previously downloaded some prepared using matlab contour model on the campaign process)

耳蜗实质上相当于一个滤波器组，耳蜗的滤波作用是在对数频率尺度上进行的，在1000HZ下，人耳的感知能力与频率成线性关系；而在1000HZ以上，人耳的感知能力与频率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(Cochlear substantially equivalent to a filter set, cochlear filter is used on logarithm frequency scale, under the 1000 hz, the perception of the human ear and a linear relationship with frequency In more than 1000 hz, the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula )
