碘化银膜的厚度主要由碘化的浓度和时间来控制。
When you disperse silver iodide into the sky, it is very hard to know whether it would have rained anyway, "Kasparian added."

为了人工降雨，气象学家黄斌明(右)和他的小组在马多附近向着天空发射碘化银炮弹。
The chemicals fired into the sky, usually dry ice or silver iodide, are supposed to provide a surface for water vapour to form liquid rain.
发射上天的化学物通常是干冰或碘化银，它们应该能为水蒸汽提供一个表面以凝结成雨滴。

实验研究表明，碘化银微粒对雪晶的形成具有极好的促进作用，雪晶的生长是一个非常缓慢的过程。
Experimental study indicates that silver iodide particles can promote the formation of snow crystals obviously and the growth rate of snow crystals is very low.
实验研究表明，碘化银微粒对雪晶的形成具有极好的促进作用，雪晶的生长是一个非常缓慢的过程。
Cloud-seeding is a technique to enhance rainfall by introducing particles - often silver iodide crystals - into cloud systems, to help condense water vapor into raindrops.
云的催化是指将催化剂颗粒打入云中使云中的水蒸汽凝聚成水滴，从而实现降雨的技术，催化剂颗粒通常为碘化银。
Physicist Jerome Kasparian, of the University of Geneva, said: "the laser can run continuously, you can aim it well, and you don't disperse huge amounts of silver iodide in the atmosphere."
日内瓦大学的物理学家热罗姆·卡斯帕里安说：“激光能持续发射，可以很好地瞄准，这样我们就不需要向大气喷洒大量的碘化银了。”
Thus, it is significant to synthesize the organic-inorganic hybrid silver (copper) iodide polymer and investigate the rule of assemble, structure and the relation between structures and properties.
因此，合成一些新型的含银(铜)-碘的有机无机杂化聚合物，研究其反应组装规律、结构规律、性能和构效关系具有十分重要的意义。
