The distributed and platform-independent software system of telecontrol mimic panel for new type of electrified railway, developed in JAVA language, realizes prompt indication of command data in mimic panel via accessing data from real-time database server.

Via mimic panel, the working status of each equipment aswell as the lines can be observed directly.

Rebuilt of power dispatching mimic board in Dagang oilfield;

A new type of mimic board control system;

The dispatch mimic board configuration and system station of Guangzhou Electric Power Bureau Dispatch Center are introduced.

：This paper sets forth a special serial-bus to process multi-site data in a computer application field by designing a simulative screen in electrical resource allocation and gives a detailed account of the key parts of the bus

The phase screen method is used for the primary study on the atmosphere effect on some system imaging and tracking accuracy of the space-point-object.

The approximation method of phase screen was used to simulate laser beam transmission in turbulent atmosphere,and its interference in turbulent atmosphere was investigated.

In order to study irradiance scintillation after laser propagating though atmospheric turbulence,the method of phase screen was adopted to simulate the optical field in the receiving plane.
