This paper discusses how to use new computer software technology to better maintain the system software and suggests several efficient methods for this purpose.

Teaching of senior workers of computer software technology is facing some difficulties,which are brought by the rapid renewal of computer softwares,various students sources,and shortage of feedback information from graduates.

By analyzed the structure of multi-media teaching software for computer software technique foundation,this paper presented a abstract model,and introduced a learning process control algorithm based on reasoning.

In order to study the performance and efficiency of soft-computing technology in application to parameter identification of complicated environmental model,a case study was presented,which was an application of water quality simulation in the Miyun Reservoir using WASP model.
