复合稀土燃烧剂与瞬态温度场的测定研究

本文阐述了燃烧剂燃烧时发出高热与高温,用以烧毁各种木质结构建筑、仓库、燃料库、军事目标、易燃千草或丛林等。而目前常用的烟火型燃烧剂虽具有燃烧温度高的优点,但却存在火种少、燃烧时间偏短的缺点;粘性石油燃烧剂或粘性石油混合烟火型燃烧剂虽然火焰面积大、燃烧时间较长,但燃烧温度低,故影响了纵火效果。作者弥补了目前各种常用燃烧剂的缺陷。现制成的复合稀土燃烧剂燃烧时具有燃烧温度高,火焰面积大,火种多,火种持续时间长的特点。 燃烧剂的燃烧温度、火焰面积与燃烧持续时间是影响对目标纵火效果的几个重要参数,尤其燃烧温度更为重要,而目前常用的接触式或非接触式测温仪,都存在某些缺点。要测出瞬态火焰温度与温度分布则难于满足要求。故作者初步应用彩色温度自动记录仪(热成象系统)测定燃烧剂的瞬态火焰温度与温度分布,现已取得良好结果,文中附有火焰彩色温度热象图,对于影响测试结果的因素还需进行深入研究。

Method for Measuring Velocity of Warhead Fragments Based on Photoelectric Detection

For measuring velocity and impacting position of single fragment of warhead, a non-contact measuring method is proposed, in which a six-light-screen array, a position indicator, a multi-channel chronograph and a computer are used.The principle of measurement is described. The key device of the system is a light screen array sensor which consists of six light screens allocated with certain geometrical parameters. When the fragment flies through the light screen array, the time of passing through each of the screens is recorded by the multi-channel chronograph.

The presented method can be used to locate the fragment and to measure the real velocity on its flying direction. It can also be used to measure the velocity of a fragment swarm after the system is engineered further.

Stability of the Third Generation Intensifier under Illumination

The stability under illumination of transmission-mode GaAs photocathode sealed in the third generation intensifier is investigated by use of spectral response testing instruments. The variations of spectral response with the illumination times under weak and intense illumination are compared. The variations of photoemission performance parameters are also characterized. The results show that during initial several weak illuminations photocathode behaves no evident decay and a maximum sensitivity is achieved, while under intense illumination the sensitivity of photocathode begin to decrease largely at the first illumination. The calculated performance parameters show that the variation of surface escape probability with illumination times is a direct cause of instability of photocathode. It is also found that under intense illumination peak wavelength is moved towards short-wave and peak response is decreased, which shows that the ability of long-wave response of photocathode is decreased.
