In this paper, the distribution and characteristics of the Earth's magnetic field are analyzed. A approach of the turns-counting applied to proximity fuze based on the fluxgate sensor is proposed. It is deduced that the output signature of fluxgate sensor is the sine/cosine function of a projectile's rotational angle. The circuit used to process signal and a micro-stored data acquisition system are designed. The projectile's turns can be exactly gained by calculating the number of the output signal cycle. In this way, the basis for precisely controlling the point blasting for the pinning round' proximity fuze is provided.

文本采用精密地磁探测仪（PCM）探测地表不同高度的地磁变化，从而可推断出地下小于20米深度的空穴、战斗部、非土质异形物。文章较详细地论述了探测机理、测试系统构成、测试数据分析。此方法可用在高速公路路基地下洞穴体、试验靶场地下弹丸寻找过程中。

In this paper, the details of micro linear zig-zag delay mechanisms is given, including some correlative figures, and the technical process of machining this micro-mechanisms by LIGA technique is shown, moreover athematics modeling for elasticity distortion of micro linear zig-zag delay mechanisms is established.

Aimed at the shortages of the higher uncertainty and the worse real-time of battlefield target identification system, the solution, that based on Digital Signal Processor and some necessary devices and circuits are designed to accomplish the high speed target identification, is put forward to. The system simulation test results obtained in this way appear to be satisfactory..

A special storage testing system for the examination of ejection canister is designed in this paper. The compositions of the storage testing system, the choosing of the sensor, the design of the power supply and hardware as well as software are presented. Testing curves of both pop-up and pop-down ejection seat are given in the paper. And the reliability of the data acquisition system for the ejection canister testing is validated through the application.
