Variations of pH and electrical conductivity in ice core record mainly depend on precipitation and the input of dissolved species. In fact, it is due to the displacement reaction of hydrogen ions and electropositive cation.

与丽江气象台站的降雨量资料比较发现，在海洋性冰川区浅冰芯pH和电导率的变化与降雨量和周围地表可溶性离子的输入量关系密切，并与降雨量呈显著的负相关关系。

As of late Saturday afternoon, the airport was closing in on one inch of rainfall with possibly another quarter of an inch on the way.

截至这个周六下午的晚些时候，降雨量已达到一英寸，同时稍后可能还会有另一场降雨量为1/4英寸的降雨，机场也因此暂时封闭。

Apart from the first week of November, the season was wet throughout, with rainfalls of 50mm measured on September 20th and 21st, October 25th and November 15th. The highest daily rainfall was 55.3mm at Valentia Observatory on October 25th.

除了9月份的第一个星期，整个季节都是湿润的，9月20日和21日、10月25日和11月15日的降雨量为50毫米。10月25日在Valentia观测台达到了最高日降雨量――55.3毫米。

Our results show that impacts of these environmental factors on geographical distributions of Chinese Chiroptera are in order of annual average temperature,days of temperature above zero degree,January average temperat...

结果表明，按其影响程度大小，影响中国翼手目动物地理分布的连续型环境因子依次为年平均气温、大于零度日数、一月份平均气温、无霜期日数、年降雨量、年平均相对湿度、七月份平均气温、海拔高度和年日照时数，其中年日照时数和海拔高度为负影响；影响翼手目种数密度分布的决定环境因子是年降雨量，但年平均气温也有明显作用。

Rainfalls can " deposit " the co2 in air , making it to take part in the process of karst , to dissolve and corrade carbonate rock . co2 concentration in soil become lower after heavy rainfall and become higher after general rainfall .( 8 ) the value of chemical characteristic of soil water in the high elevation area is lower than that in the low elevation area

降雨可以对coz产生影响，&沉淀&大气中的co ：，使其参与到岩溶作用中，溶蚀碳酸盐岩；降雨对土壤空气中coz的影响与雨强、雨量有关，降雨量、雨强较大时，土壤空气中的c02产生受到抑制，降雨量和雨强较小时，土壤空气中的coz浓度升高。

On the base of probabilistic and statistics results of joints and cracks, the Author modifies Block Theory. The sliding probability of Key Block is I A RSTR A CT F2 ? 5.It is put up forward that GM(l,1) Model to predict Amount of rainfall, and Markov Chain to modifY GM( 1,1 )predicting result, and then a theoretical predicting Model of amount of rainfall is firstly built. This model is applied in a situ example. It is proved that the model is very useful to predict amount of rainfall ,when ordinal array of Amount of rainfall changes in unexact index rule.

首次将节理裂隙视为有限长，借助有关岩体节理裂隙概率统计研究成果，对块体理论进行修正，确定了关键块体变为滑动块体概率计算公式为 5、本文提出采用GM（1，1）模型预测降雨量，而采用Markov链进行修正的方法，首次用该方法建立了大气降雨量预测的理论模型，并结合实例进行具体应用，解决了当降雨量的时间序列呈不严格的指数规律变化时，大气降雨量的预测问题。

The experimental results show that there is no runoff on test slops of any declivities with rainfall less than 9mm, and the runoff efficiency and rainfall are in direct proportion with rainfall larger than 9mm, which is more obvious on slope than on flat land.

试验结果表明，降雨量小于9mm时试验坡度的草坪绿地均不产流；次降雨量大于9mm时，绿地的径流效率与次降雨量成正比，而坡地上二者的相关性比平地更加显著。

Through the topographical survey, literature research and analysis of the remote sensing images, we shall emphasize on the five factors of water conservancy, water flow, streams, water retaining and water utilization in the upper reaches of the river, which are interacted and interplayed.

研究结果表明，漓江为雨源性河流，降雨时空分配极不均匀，70%的降雨量集中在漓江上游区域，全年62.7%降雨量和降雨时间集中在四个月内(即4～7月)，最大的日降雨量可达415.8mm；降雨量最小的月份出现在12月至翌年1月，仅100～110mm，占全年降雨量的6%左右，由此直接影响流域河川径流季节性的变化，造成洪水期和枯水期现象，周期性水量的变化是不为人们意志改变的一种自然规律。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
