After analyzing the weldability of galvanized steel plate with seam welding,the application of general seam welding machine instead of special purpose one in welding of galvanized oil - tank is studied, the measure of preventing electrode from adhesion of Zn and Cu- Zn alloy is put forward.

The improved algorithm of mailbox-based mobile agent communication mechanism;

Design and implementation of communication mechanism in Elanix server;

A multiprocessor communication system is designed in this paper based on the multi-CPU digital submerged arc welding system,and the realization of communication is discussed in detail.

The aim of this paper was to instruct the troops to make scientific and rational use of the communication workshop, and implement legalized and standardized management, so that to ensure the physical health of officers and men of communication troops and to uphold their combat effectiveness.

By way of an experiment on air heat exchanger used in the communication equipment plant,obtained the heat transfer performance and pressure drop of the air heat exchanger etc.
