Contemporary artificial rainfall is artificial rainfall basically is principle of basis nature rainfall, launch activator from the ground through the plane is spread or using tall artillery piece, rocket, wait like silver iodide, dry ice, liquid nitrogen, drop cloud layer temperature thereby, form supersaturation lunt; to perhaps condense to the boardcast sowing in the cloud layer that contains supersaturation lunt nucleus, increase the ice crystal amount in the cloud, increase the amount of drip-drop and diameter then, raise cloud precipitation change rate, achieve the goal that raises precipitation of bureau ground nature thereby.

二、现代的人工降雨人工降雨主要是依据自然降雨原理，通过飞机播撒或利用高炮、火箭从地面上发射催化剂，如碘化银、干冰、液氮等，从而降低云层温度，形成过饱和水汽；或者向含有过饱和水汽的云层中撒播凝聚核，增加云中的冰晶数量，进而增加雨滴的数量和直径，提高云降水的转化率，从而达到增加局地自然降水的目的。

The composition of the samples was detected using a mass spectrometer with a computer.

In the paper, the electrode system of the original TL/TSC measurement instrument is improved, which greatly facilitates sample exchange and increased liquid nitrogen's running and cooling speed. Through long time and repeated practice we finally find an effective method to prepare films. We've synthesized a new kind of organic photo-refraction material nitryl azobenzene grafting PVK and characterized it with IR spectra. We've also synthesized 5OCB and found the optimal mass ratio of PVK/5OCB/C60-49.8:50:0.2, and given the two-beam coupling testing result.

本文的主要工作是：首先对传统热发光和热激电流测量装置的电极系统进行了改进，使其在换取样品，液氮流动、冷却速度等方面都有了很大提高；摸索了较适合于热激实验的成膜方法；合成了一种新型的有机光折变材料硝基偶氮苯接枝PVK，并对其做了红外谱表征；合成了生色团物质5OCB，找到PVK/5OCB/C_(60)的最佳配比为49.8：50：0.2，并对该体系做了初步的光学测试。

The calculated results show that there is an obvious difference between the interfacial tension of the bulk liquid nitrogen and that of the adsorbed liquid nitrogen film on most of nonporous so.
