国家软件标准定义,开发软件的一个流程都在这里了(National software standard definition, software development process are all here in one of the)

说明：  QPSK（四进制相移键控）信号的产生及调制解调过程（经高斯和瑞利信道）的仿真(QPSK (quaternary phase shift keying) signal generation and modulation and demodulation process (by the Gaussian and Rayleigh channel) Simulation)

电磁转矩电动机广泛应用于电液伺服阀。它们有助于扭矩转换成比例的控制电流。(The electromagnetic torque motors are widely used in electrohydraulic servovalves. They serve to convert the control current into a proportional torque. For more details about this issue, please refer to my book:)
