气温序列非均一性检验方法的研究

A Study of Testing Methods on Inhomogeneity of Temperature Sequences

摘要: 采用距平累加法、连续t-检验及回归检验法对分布於25个省(区)31个站的气温序列进行了非均一性检验。结果表明这3种方法在显著性水平α=0.01时，能有效地检验气温序列的非均一性，其结论适用於全国。

Abstract: Based on cumulative-departure, successive t-test and regressive methods, the inhomogeneity tests of temperature sequences for 31 stations in 25 provinces are conducted. It is shown that the three methods are valid for inhomogeneity tests of temperature sequences with the significance level a=0.01. And, the conclusions apply to the whole country
