描述----------Description----------
Does dropping silver iodide onto clouds increase the amount of rainfall they produce? In a randomized experiment, researchers measured the volume of rainfall in a target area (in acre-feet) on 26 suitable days in which the clouds were seeded and on 26 suitble days in which the clouds were not seeded.
下降碘化银上云量增加,他们所产生的降雨吗?在一个随机的实验中,研究人员测量降雨量在目标区域的体积(在英亩 - 英尺),适合于26天,其中云分别接种和于26 suitble天内云不接种。
