采用matlab软件进行的移相全桥仿真研究（恒电流）(Carried out using matlab software simulation of phase-shifted full-bridge (constant current))

偏微分方程中关于有限差分的其中一个格式，向前差分格式(failed to translate)

在无数点中，寻找一条直线，在高书中用的是两点确定一个直线，而在此用的是对比两个点，然后求平均值，以此类推(In many points, to find a straight line, is used in the two high book to determine a straight line, and in this contrast with the two points, and then averaged, and so on )

选择映射法实现降低OFDM的峰值平均功率比的仿真(Mapping method chosen to achieve lower peak to average power ratio of OFDM-Simulation)

说明：  此程序为语音信号的过零率检测，白噪声过零率远远高于语音信号，故可通过对过零率的检测判断出是不是语音信号。(This procedure for the zero rate of speech signal detection, white noise zero crossing rate is much higher than the speech signal, it can zero rate by detection of voice signal is not judged.)
