The working principle and measuring method of particle size determination for liquiddroplets carried in gas flow by using impact diaphragm method have been presented, and the operation steps for applying magnesium oxide film or vaseline film on the carrier glass being given.

Study on the Performance of Change-over Switch Used in the Slapper Initiating System;

Based on the low inductance technology and parallel-plate transmission principle,an experimental apparatus of small-scale slapper driven by electrical explosion was designed and established,which was used to initiate primary high explosives.

[Purpose]Approach for the clinical effectiveness of prolapse of lumbar interver tebral disc by peridural impact with tractional manipulation.

The advantage of perforating projectile consisting slapper detonator,is analyzed in this paper and the performance analysis is based on the initiation principle,initiation model,computation,and test results of the explosive foil initiator.

This paper introduces the development and application of slapper detonator and describes the design principle and structure of slapper detonator.

Slapper detonator is a new type high-octane portfire, which is only sensitive to short pulse, and consequently it has strong abilities to resist the electromagnetic interference and radio-frequency interference, and it also has great reliabilities.
