| 摘 要： | 本文利用多元回归分析方法对福建省古田水库地区1975—1984年人工降雨效果进行统计分析。十年共进行228次随机试验,其中催化113次,统计结果平均相对增雨24.16%,绝对增雨1.24mm/3h。分析结果还表明:由于所挑选的因子与降雨之间有内在物理联系,所以这种方法不仅能提高人工降雨效果检验的可靠性,缩短试验周期,而且还便于选择有利的催化条件,避免盲目性,提高人工降雨效果。

| Abstract: | We intend to make a multivariate statistical analysis on the effective-ness of random experiments of artificial rainfall in Fujian Gutian reser-voir for ten years(1975-1984).We have made 228 randomized experiments during the ten years, 113 of which were seeded. The results of the statistical are: relative increased rainfall 24-16% and absolute increased rainfall 1.24mm/3hr in average,The result of analysis points out that because there exist internal physical relations between the selected factors and natural precipitation, the reliability of the result analysis of artificial rainfall can be raised, and the experiment period reduced. Meanwhile, this method makes it easy to select powerful seeding conditions, refrains blindness and improve the result of artifical rainfall. |
