采用临界比例度法计算系统P、PI、PID控制器参数，绘制整定后系统的单位阶跃响应曲线。(The critical proportional method is used to calculate the parameters of P, PI and PID controllers, and the unit step response curve of the system after setting is drawn.)

基于计算机实验数据建立一个克里金近似模型，并将其用作计算机模型的代理模型。这里，计算机实验是指通过运行计算机模型获得的若干组输入和响应数据。而计算机模型的这些输入或响应数据都有可能是高维的。(The typical use of this software is to construct a kriging approximation model based on data from a computer experiment, and to use this approximation model as a surrogate for the computer model. Here, a computer experiment is a collection of pairs of input and responses from runs of a computer model. Both the input and the response from the computer model are likely to be high dimensional.)
