探讨蒸发量与气象要素之间的关系，分月建立了逐步回归方程，经检验可作为蒸发量的一种客观预报方法。

Stepwise regression equation in each month is established based on the relationship between evaporation and meteorological elements, which is an objective forecast method of evaporation.

统计预报主要依赖于紫外线的实测资料和对相关气象要素的观测。

The Statistics Prediction mainly relies on the monitored data of UV and the observation of relative meteorological factors.

浓度同气象条件关系密切，本文采用一元统计方法对二者进行相关性分析，从而得到对PM_（10）污染影响显著的气象要素，作为后续进行PM_（10）浓度预报的依据。

There is a close correlativity between PM_(10) concentration and meteorological condition, so one-member statistical method had been used to analyst the correlation between them according to season.
