0 前言 水面蒸发量与水位、雨量等水文参数一样,是水文水资源勘测中的一项重要参数,所不同的是,其自动观测在国内外却是一道难题。 目前,水面蒸发量基本上仍采用人工量测方法,例如,使用测针测量蒸发桶内水面高度。自记仪器有使用浮子式的,但是性能指标和自动化程度不理想。南京水利水文自动化研究所研制并通过鉴定的FZZ-1型遥测蒸发器采用了一种新的设计原理(专利号为ZL94231758.0)。它可以实现水面蒸发量的
0 Introduction Water surface evaporation is an important parameter in the hydrological and hydrological water resources survey, just like the hydrological parameters such as water level and rainfall. The difference is that the automatic observation is a difficult problem at home and abroad. Currently, the water surface evaporation is still basically used manual measurement methods, for example, the use of stylus measuring the height of the surface of the water barrel. Self-recording devices have the use of float, but the performance indicators and the degree of automation is not ideal. Nanjing Institute of Water Conservancy and Hydraulics developed and passed the identification of the FZZ-1 telemetry evaporator using a new design principle (Patent No. ZL94231758.0). It can achieve water evaporation
