Bacterial ice nuclei are proteins , named ice nucleating proteins , coded by ice nucleating genes , and 11 ice nucleating genes have been cloned , sequenced and expressed in " escherichia coli " 细菌冰核是一类蛋白质,称冰蛋白,由细菌冰核基因编码,据报道已有11种冰核细菌的冰核基因被克隆并在大肠杆菌中得到表达。
The main mechanism of enhancing precipitation is that much ice nuclei turn into ices , and then snow ; graupel are formed more by microphysical processes . the melting of graupel makes precipitation more than that of unseeded clouds 主要的增雨机制是大量冰核活化成冰晶,冰晶通过增长和其他的微物理过程形成雪晶、霰,霰最后融化成降水使地面降水量增加。
They used aircrafts to release man - made particles made of dust in the sky . then they collected and measured the ice nuclei freezing nuclei . it showed that in the presence of those man - made particles , the size of the snow crystal were considerably bigger than natural one 他们使用飞机在天空中投放一些以尘埃做成的人工粒子,然后收集和量度冰核凝结核,证实了利用人工粒子形成的雪花比那些天然形成的更大

The paper works out the ice crystal spectrum distributing in the different macroscopic and micro - backgroud of the cloud ( ie , the thickness , the temperature and the supersaturation with respect to ice of the nucleation layer ) . this paper also works out the amount of catalyst which is allowed in the cloud nucleation layer according to the different quantity of the supercooled water , the density of the supersaturation of the vapor with respect to ice . simultaneously , the paper discusses the i nfluence of remaining time when seeding artificial ice nucleus in the different ascending - velocity and altitude , and elicits the proper seeding altitude of the catalyst 以此解为依据,得出了不同均流时,人工引入冰核在核化层存留时间,再以此时间作为人工冰核凝华增长时间,求出不同的云宏微观背景(如核化层厚度、温度、冰面过饱和度等)下的冰晶谱分布,经和实际资料比对符合相当好。进而求出核化层中不同过冷水量、冰面过饱和水汽密度下云核化层可允许的催化用量。同时讨论了不同升速,不同高度引入人工冰核时对其存留时间的影响。
