Measures of Construction Quality of Backfill in Earthwork in Rain Spell

年降水量变化呈双波型，在1971和1995年发生两次突变，且都是由多雨期转为少雨期：蒸发量在波动中减小，其趋势系数为0.33（P0.01）。

The annual precipitation show double wave variation , there were two mutations respectively in 1971 and 1995 , and both from pluvial period to less rain ones ; evaporation deceases in fluctuation . the trend coefficient is 0.33 ( P 0.01 ) .

3条支流中4个化学指标（NO3&N、NH4+-N、TP、CODMn）在各个雨期之间浓度变化具有十分相似的规律。

Four chemical parameters , including NO ~ + _3-N 、 NH ~ + _4-N 、 TP and COD_ ( Mn ), in three tributaries had similar trends among three seasons .

特殊气候原因而形成雨期集中；

The intensive rainy period due to the special climate ;

In the late1990s , precipitation in spring sowing of Guangxi enters its cycle of less raining .

低洼地区和涌出口在雨期会受潮水顶托，采用泵排方式。

Moreover , in the low-lying area and the outlets of creeks , pumps will be used to discharge the rainwater .

19世纪末至20世纪初，降水明显减少，再次进入相对少雨期；

From the end of the 19th century , the precipitation decrease obviously , the climate turned into relative droughty period again .

江淮流域2003年强梅雨期的水汽输送特征分析

A Diagnostic Study of Water Vapor Transport and Budget during Heavy Precipitation over the Changjiang River and the Huaihe River Basins in 2003

研究结果表明，沼泽湿地蒸发量在夏季少雨期高于农田，秋季多雨期低于农田；

The result shows that during rainless summer evaporation of wetland is higher than that of farmland , but during rainy autumn is lower than that of farmland .

在无雨期该生态系统可以处理一部分城市生活污水，实现削减污染和保持系统稳定的双重功能。

When there is no rain some municipal wastewater can be treated in this ecological treatment system to achieve the purposes of minifying pollution and stabilizing the ecological system .

未来10～15年，海河流域、黄河流域和淮河流域仍将处于少雨期。

So we make a preliminary prediction that the Haihe River , the Yellow River and the Huaihe River will still maintain rainless period for another 10 to 15 years .

渗滤液调整池容量应确保满足渗滤液迅速从填埋场排出的需要，其存储能力不是按年平均降雨量计算而应按多雨期的降雨量来计算。

The capacity of leachate regulating & storing tank is capable of demand of discharge leachate from garbage rapidly , accounted according to precipitation in period of rain season , instead of average precipitation .

西安的降水变化存在明显的年代际波动。自1736年以来，共经历了6个多雨期与7个少雨期，其中多雨期的平均雨量比少雨期多16%。

Precipitation changes have obvious inter-decadal fluctuation , experiencing six rainy periods and seven drought periods in Xi'an since 1736 , in which the mean precipitation in the rainy periods is 16 % more than that in drought periods .
