This paper analyzes the reasons of sparking of exciter, and advances some corresponding schemes fortreating this problem.

In view of the sparking existing commonly in magnetic powder flaw detection for RD 2 type wheelsets, it begins with the analysis on the magnetizing method in magnetic powder flaw detection and the contact conditions between the end face of wheelset and the magnetizing fastener, and the preventative measures and suggestions are put forward.

It can improve the breakdown field and reliable performances, reduce and even remove the defections such as creepage, sparking,breakown and so on in working.

The magnetron is the key component of a microwave oven, and arcing often occurs on the production line because of bad matching between the magnetron and the cavity, which lead to great waste of material and an increase in manufacturing cost.

This paper analyses the arcing often occurred in the power slip-ring of a radar and discusses the design and application of power slip-ring.

This paper analyses the arcing often occurred in the power slip-ring of a radar,discussing the design and application of power slip-ring.

To study the integrated decision-making of the fire and electronic warfare in the single to multiple attack,the target sequencing algorithm of the fire attack is put forward by considering the effectiveness of the jamming system.

By analyzing the factors which influence on digital tank company’s fire strike capability, an evaluating index system is built up in the paper.

Aiming at the security of equipment materials distribution center in the war,the paper discusses the influence factors of addressing model of equipment materials distribution center under condition of modern war,proposes the least cost and the shortest time addressing model of equipment materials distribution center based on fire strike.
