摘　　要：本文运用车贝雪夫多项式方法分析了东亚西风带(90—150°E,35—55°N)和西太平洋副高活动区(110—170°E,15—35°N)月平均500hPa高度场低阶车氏系数的若干特征,探讨了两区低阶车氏系数与长江中下游6、7月雨量之间的关联。In this paper, the height of 500hPa in the area 90--150°E, 35--55°Nand 110--170°E, 15--35°N are resolved with Chebyshev polynomials.The features of Chebyshev's coefficients and relation ships between someof the coefficients and precipitation in the middle and lower reachesof the ChangJiang River are analysed.
