Abstract: 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.
