摘要
我国现行使用的E_(601)型水面蒸发器,由于测针铁支架造成蒸发量偏大,器内水位变化使蒸发量不稳定和溢流系统不完善等问题,观测误差和环境因素干扰较大。作者根据影响水面蒸发因素的观测研究,去掉测针(及支架),加强溢流系统,于1983年试验推出E_(601K)型水面蒸发器,经多年使用,其测值比改进后的E_(601)偏小10.9%,埋于湖边滩地可测湖面蒸发量。曾得到施成熙先生的肯定。
The E_(601)type of water surface evaporator which is populally using in china has more ob-vious observation error and is considerabely obstructed by environmented factors becauseTron brace of observation needle causes greater evaporation then used, the change in waterlevel in the evaporator gets evaporation unstable and overflowing system unperfect. Accord-ing to evaporation, author demounted the observation, needle and Trace, improvingoverflowing system. In 1983, the E_(601)Ktype of water surface evaporator was tested and devel-oped. After many years of application, some experimental results were obtained, The meas-ured value is 10.9% smaller than improved E_(601)type, E601kevaporator was buried near a lakebank, which can correctly provide evaporation value of lake face.
