While cloud seeding has existed for some time it is not considered a safe way of creating rainclouds because it involves filling the atmosphere with small particles such as dry ice and silver iodide. 虽然云的催化技术已存在一段时间了,但一般认为制造雨云不太安全,因为这需要向大气中喷洒像干冰和碘化银这样的小粒子。
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。
You can also turn the laser on and off at will, which makes it easier to assess whether it has any effect. When you disperse silver iodide into the sky, it is very hard to know whether it would have rained anyway, Kasparian added. 你可以随时开关激光,这样就能更容易地评估它是否有效了。而在天空中喷洒碘化银则很难判断其降雨效果。

Cloud seeding works by encouraging moist air to turn into rain, often by sowing silver iodide crystals into moist air to speed up the creation of raindrops ( or snowflakes, in this case). 云种散播的原理是推动湿空气转变为降雨,具体方法常常是向湿空气播撒碘化银晶体,以加速雨滴(或雪花,就像此次情况这样)的形成。
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。
