The real experiment is to use computer programming to simulate the behavior of the experimental process. The simulation experiment needs a lot of parameters, and it also needs to run a program that conforms to the real situation.

The parameters of the simulation experiment are all obtained through a large number of previous experiments. The purpose of simulation experiment is to save raw materials, and at the same time, the results of simulation experiment can be compared with the results of real experiment, and the correctness of various theorems and laws summarized from the experiment can be tested.
