编制阶跃响应与方波响应相互转化的程序、由阶跃响应数据获得对象传递函数模型的通用程序、由阶跃响应数据获得对象微分方程模型的通用程序。并通过一个传递函数进行验证（阶跃响应和方波响应数据可利用simulink生成）(A program for converting step response to square wave response, a general program for obtaining transfer function model from step response data, and a general program for obtaining differential equation model from step response data are compiled. It is validated by a transfer function (step response and square response data can be generated by simulink))
