用Na、K、Mg和NH_4的氯化物和硫酸盐以及其它碘化物在盐浓度为0、0.01、0.1和1M时测试了碘化铅的冰成核活性。研究发现，氯化物盐会降低PbI2的成核活性，而硫酸盐在一定浓度下会促进PbI2的成核。在K、Rb、Cs和NH_4的碘化物中，NH_4I使PbI_2的活度显著提高约2°C，而其它碘化物对PbI_2的活度没有明显的影响。从定性的角度讨论了可溶性物质活性的可能原因。
The ice nucleating activity of lead iodide was tested with chlorides and sulphates of Na, K, Mg and NH4and other iodides at salt concentrations of 0, 0.01, 0.1 and 1 M. It has been found that the chloride salts deteriorate the nucleation activity of PbI2while sulphates help nucleation at certain concentrations. Among the iodides of K, Rb, Cs and NH4, NH4I has remarkably increased the activity of PbI2by about 2°C whereas other iodides do not show any appreciable change in the activity of PbI2. The possible causes for the activities of the soluble materials have been discussed on certain qualitative considerations.
