摘要利用劈尖干涉方法测量了室内无风环境下水面蒸发量，并与精密天平测量结果进行了比较分析。相比于精密天平测量方法，劈尖干涉法，虽然测量结果偏小以及测量数据波动性略大，但是由于测量过程中无需移动蒸发容器，测量操作对水面蒸发不产生干扰，因而劈尖干涉法测量结果更为准确可靠。利用劈尖干涉原理测量水面蒸发量，不仅测量精度高，理论上蒸发量的最小测量极限可达 2 μm，可将被测蒸发时长缩短至 10 分钟，甚至更短;而且避免了测量操作对水面蒸发的干扰，实现了无风环境
下短时间水面蒸发量的无操作干扰测量。

Abstract: Water surface evaporation in windless environment was measured by wedge interference．Compared
with precision balance method，the results measured by wedge interference were slightly smaller，and the
fluctuation of data was slightly larger．But evaporation container was no need to be moved during the measurement
process of wedge interference．The measurement operations did not interfere with water surface evaporation．So，the
results of wedge interference are more accurate and reliable．The measurement of water surface evaporation by
wedge interference not only has high accuracy，but also is unaffected by operations．The measured evaporation
time can be shortened to less than 10 minutes．Wedge interference method realizes measurement of short-time-
interval water surface evaporation without operation interference in windless environment．

Key words: wedge interference water surface evaporation short-time-interval no operation interference
