中文摘要: 对聚苯乙烯测雹板性能的检定试验以及1988~1998年野外观测取样结果表明:(1)聚苯乙烯测雹板性能稳定,吸湿性差,能经受风吹、雨打、日晒,不变形、不变质,适合在野外雹暴天气中使用。(2)聚苯乙烯材料弹性小,测量误差小,模拟风、雨等天气条件时,平均误差为43%~122 %。因此,可以较准确地测出野外实际冰雹大小及数密度。
Abstract:The performance tests for the hailpad made by polystyrene material were done in laboratory. From 1988 to 1998 hailpad were used in the field obsevation for sampling hailstones. It was showed that the hailpad almost could not absorbe water and but could stand wind , rain and sunshine in out-door conditions.The polystyrene material was uniform and its elasticity was small .The hail trace size on it was used to estimate the real size of hailstone and the average errors were from 4.3% to 12.2%. Therefore ,the diameter and number density of hailstone could be measured accurately.
