超声波式自记蒸发仪的生产应用

The Application of Ultrasonic Type Evaporation Recording Instrument

本文依据汉口某地面气象自动观测系统的自记资料及同步的人工观测蒸发量,来分析超声波式自记蒸发仪的精度,并对超声波蒸发仪受环境因素影响进行了分析,还验证其中一种常用水面蒸发量计算公式的精度。本文中参考诸多自动蒸发方面的文章,在收集资料时注意自动蒸发与人工观测的不同,改进方法提高自记蒸发量的精度。

According to the auto-recording data of a ground automatic meteorological station in Hankou and those of synchronous evaporation by manual observation, we analyzed the accuracy of ultrasonic type evaporation recording instrument, evaluated the impact of environmental factors on the ultrasonic evaporating and verified the accuracy of one commonly used water surface evaporation capacity calculation formula. While collecting the reference articles, we noticed the difference between automatic evapora- tion and manual observation, so as to change the method to improve the accuracy of recording evaporation.
