The function of the boiler's water-supplying automatic control system is to make the amount of evaporation match the Vapor's water level in provision of the scope and raise the safety and the economy of the boiler and the steam turbine.

汽包锅炉给水自动控制的任务是使锅炉的给水量适应锅炉的蒸发量，以维护汽包水位在规定的范围内，以提高锅炉和汽轮机的安全性和经济性。

The statistic shows the amount of evaporation on surface water is decreasing.

统计资料结果表明，水面蒸发量呈明显减少趋势。

The annual mean amount of evaporation is larger than that of precipitation, and their values are 888.0 mm and 677.2 mm, respectively, so the annual mean net moisture flux is-210.8mm;

青岛沿海年平均蒸发量大于降水量，量值分别为888.0mm和677.2mm，年平均净水汽通量为-210.8mm；

Analysis of spatiotemporal distribution and tendency of amount of evaporation in Anhui Province

安徽省蒸发量时空分布及变化趋势分析

The amount of evaporation in Yangtze basin and Three Gorges zone will increase only by several thousandths;

兴建三峡水库后，流域及三峡区间的蒸发量只增加了千分之几；

A study of the amount of evaporation and the loss of heat for evaporation in China

我国陆面蒸发量和蒸发耗热量的研究

The results show that the heat conduct loss will increase and the amount of evaporation will decrease while the electron beam width is too narrow and the electron beam power density is above 15kW/ cm 2.

并得出电子枪束宽过窄，电子枪功率密度高于15kW／cm2时，会使导热损失增加、蒸发量减少的结论。

Improved method for computing amount of evaporation and potential evapotranspiration

计算蒸发量蒸散发能力的改进方法

The characteristics of arid and semi-arid Northwest China includes great amount of evaporation, small amount of rainfall and light and heat resources, these are necessary conditions for exploitation and development of artificial oasis.

中国西北属干旱、半干旱地区，于是蒸发量大、降雨量小，光热资源充足为当地的主要气候特征，为人工绿洲的开发与发展准备了前提。
