摘要
为有效实现蒸发的自动记录与存储,长江委水文局研制生产的CJH-E1型降雨蒸发系统,具有计量精准、结构简单、操作便捷、运行稳定等优点。该文介绍了该系统的结构、性能、工作过程及简易操作流程。并以黄家港水文站的比测为例,分别以天、月为单位,分析了该系统的降雨、蒸发误差,从而计算出单月、总量的平均误差,能够满足《水面蒸发观测规范》。为该系统的顺利投产提供了理论与实践依据。
In order to effectively realize the automatic recording and storage of evaporation,cjh-e1 rainfall evaporation system developed by Hydrological Bureau of Yangtze River Commission has the advantages of accurate measurement,simple structure,convenient operation and stable operation.This paper introduces the structure,performance,working process and simple operation flow of the system.Taking huangjiagang hydrological station as an example,the rainfall and evaporation errors of the system are analyzed in the unit of days and months,so as to calculate the average error of single month and total amount,which can meet the requirements of"water surface evaporation observation specification".It provides a theoretical and practical basis for the smooth operation of the system.
