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.

汽包鍋爐給水自動控制的任務是使鍋爐的給水量適應鍋爐的蒸發量，以維護汽包水位在規定的范圍內，以提高鍋爐和汽輪機的安全性和經濟性。

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

統計資料結果表明，水面蒸發量呈明顯減少趨勢。

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;

青島沿海年平均蒸發量大于降水量，量值分別為888.0mm和677.2mm，年平均凈水汽通量為-210.8mm；

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

我國陸面蒸發量和蒸發耗熱量的研究

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.

并得出電子槍束寬過窄，電子槍功率密度高于15kW／cm2時，會使導熱損失增加、蒸發量減少的結論。
