| 摘 要： | 文章主要根据水体"热胀冷缩"的原理,计算不同水温对应的水位高度,通过对这种水体体积变化进行蒸发数据的补偿进行研究探讨,得到一个接近真实蒸发情况的补偿数学方程式,以获取更加准确的蒸发量数据。通过对2017年4月、8月、12月的数据进行研究分析,得出实测蒸发量与水温、4℃水位及实测蒸发量和修正蒸发量差值之间的相关性以及影响因子。

| Abstract: | Based on the principle of thermal expansion and contraction,this paper calculates the water level corresponding to different water temperature.The compensation of evaporation data for the change of water volume is studied,and a compensating mathematical equation closer to the real evaporation situation is obtained,which can get more accurate evaporation data.According to study and analyze the data of April,August and December in 2017,the correlation and impact factors between measured evaporation and water temperature,water level at 4℃,and the difference between measured evaporation and corrected evaporation are obtained. |
