中文摘要:
      1981年吉林省气象科学研究所等单位研制出,在自然云雾中复制固液态粒子的光固印模新技术。作者将此项技术扩展应用到实验室条件下,复制人造冰晶和雾滴。直径几微米至100微米的人造冰晶和雾滴的印模实验指出:光固印模法复制云室冰晶非常理想,印模清晰,失真度小,并能保存,可取代现用糖液检测冰晶的方法;由于光固液膜对小雾滴的捕获效率低,并受取样时环境的温度、湿度和取样风速的影响严重,所以用它复制雾滴受到一定的限制。
英文摘要:
      A new technology for replicating liquid and solid particles in natural clouds based on photosolidifing replication principle was developed by Jin Lin Institute of Meteorological Reseach etc. in 1981.Author's work shows that the photosolidified replication method can be used to measure artificial crystals and droplets in the laboratory. The experimental results show the photosolidified replication of artificial crystals whose diameters are from 100°μ to 100μ is satisfactory so that it may be used to replace the method of sugar solution.The patterns of crystals on the replications are clear, less deformed and easy to preserve. But it is difficult to catch small droplets with photosolidified thin film and the quality of replication is greatly effected by environment temperalure, humidity and sampling wind speed. Therefore the usefulness of this method is restricted.
