With the development of computer technology, multimedia technology and network technology, virtual simulation experiment technology has been produced. Especially with the development of distance education, people pay more and more attention to practical teaching. Distance experiment teaching is considered to be an effective method to break the time and space limitation. Researchers or students can collaborate with peers, share or monopolize equipment, share data and computer resources, and gain remote instruction from teachers. Therefore, in view of the need to summarize the disadvantages of traditional distance education practice, it is of great significance to open relevant virtual practice with computer.
