逆变器死区效应分析与补偿方法.: 针对电压源型空间矢量脉宽调制逆变器的死区效应， 提出了一种根据电流矢量判断电流极性的死区补偿方法， 分析了因死区时间、 功率器件导通关断时间引起的误差电压矢量.(Inverter dead time effect analysis and compensation method.: For the voltage source space vector pulse width modulation inverter dead time effect, we propose a judgment based on current polarity current vector deadband compensation method to analyze due to death-time, the power device turn-off time due to the error voltage vector.)

该程序用于倾角传感器的温度补偿，利用反正弦法来计算角度

说明：  编程计算图形的面积。程序可以计算圆形，长方形，正方形的面积，运行时先提示用户选择图形的类型，然后，对圆形要求用户输入半径值，对长方形要求用户输入长和宽的值，对正方形要求用户输入边长得值，计算出面积的值后将其显示出来。(Calculate the area of graphics programming. Program can calculate the round, rectangular, square area, run-time prompts the user to first select the type of graph, and then the radius of the circle requires the user to input the value of the rectangle requires the user to input the length and width values, requires the user to input side of the square grow the value to calculate the value of the area after the show.)
