| 摘 要： | 对临汾市1976年～2008年的7个气象要素进行了均一性检验,结果表明:降水、地温、水汽压未通过正态检验;日照通过了标准正态均一性检验SNHT;气温、气压和相对湿度检测出间断点.t检验和SNHT检验的结果不完全一致.更换仪器和迁站是间断点出现的主要原因.

| Abstract: | Seven meteorological elements such as precipitation, soil temperature, vapor pressure, sunshine, temperature, pressure and relative humidity, were determined by homogentiety test. The rests showed that precipitation, soil temperature and vapor pressure didn＇t pass the normality test; sunshine pass the standard normal homogeneity test （SNHT） ; temperature, pressure and relative humidity presented the detecting discontinuity. The conclusions between t test and SNHT were not consistent. And the main reasons for the emergerce of discon- tinuity point was the replacement of equipment and moving the station. |
