The paper are studied dynamics characteristic of IR smoke under entironment to vacuum and micro-gravitation,based maths-model of thermodynamic onflow pervasion by smoke formed, the experiment proves that the movement speed of smoke gradually minishes along with hoist of vacuum.The process after smoke formed analysed ,which proves that its movement rule relates hilum of particle.

本文对真空和微重力环境下的红外烟幕进行了动力学特性研究，建立了烟幕形成过程中的热力湍流扩散数学模型，通过实验表明随著真空度的升高，烟幕的运动速度逐渐减小；并对烟幕形成后的过程进行了分析，结果表明其运动规律跟粒子的粒径有关。

H-BN thin films were prepared on the (100)-oriented surface of n-Si by r. f. sputtering physical vapor deposition. The field emission characteristics of the BN films were measured in a ultra high vacuum system. It has been found that the field emission characteristics of BN films is affected evidently by substrates temperature.

利用射频磁控溅射方法，真空室中充入高纯N2(99.99%)和高纯Ar(99.99%)的混合气体，在n型(100)Si基底上沈积了六角氮化硼薄膜，在超高真空0^(-7Pa系统中测量了BN薄膜的场发射特性，发现沈积时基底温度对BN薄膜的场发射特性有很大影响。
