中文摘要: 利用1993年4—6月共4次南京降雨过程中取到的GBPP－100资料与滤纸斑点法所取资料，通过对应资料的雨滴谱基本参量的计算分析，研究GBPP－100用于外场观测的可行性。结果表明：在瞬时雨强度变化缓慢且雨强小于160mm·h－1的阵性降水和非阵性降水过程中，GBPP－100完全可代替滤纸斑点法用于外场观测，对雨强变化迅速阵性降水GBPP－100与滤纸斑点法取样结果差异较大，其原因还有待进一步研究。

Abstract:The raindrop size distribution was measured for four times during the period from April to June, 1993. The data of measurement were compared with the observation data of filter paper. Based on the two categories of data the basic parameters of raindrop size distribution were calculated and some statistical calculations were made. Using this method the usability of GBPP-100 raindrop disdrometer on field experiments was discussed. The results indicate that: (1) the GBPP-100 can be used on field observation instead of the filter paper during the period that the rainfall intensity slowly changes and is smaller than 160mm/h; (2)there are some obvious differences between the two categories of measurement when the rainfall intensity of shower rapidly changes.
