摘　　要：用ＧＢＰＰ－１００型地面雨滴谱仪与吸水纸斑，点法进行同步观测，对比分析ＧＢＰＰ－１００型地面雨滴谱仪测量的可靠性。结果表明：（１）两种方法测量雨滴谱所得资料除平均直径、均立方根直径相似性稍差外，其它特征量的线性相关显著性水平均为０．００５；（２）两种方法所得雨滴谱资料除平均直径、均立方根直径、降水强度稍有差异外，其它特征量均无显著差异。Observation was made with the ground raindrop size meter synchronously with a hygroscopic paper for the spots to investigate the reliability of the meter measurements。Results show that l)both types of data yield the significance level of 0.005 for the characteristic quantity linear correlation except the mean diameter,mean square rcot diameter similarity and 2)double factor variance analysi indicates that no significant difference exists in the characteristic quantities but mean diameter and mean square rcot diameter of the size distribution and rainfall intensity.
