海面蒸发量测量工具的改进

海面蒸发是海气相互作用的重要途径之一，是地球上热能交换的重要因子，海面蒸发量的测量对海气通量交换的研究具有十分重要的意义；但是目前国内广泛应用的测量工具都不适合在调查船上使用。文章介绍了一种经过改进的适用于船上测量海面蒸发量的试验装置，从它如何消除船舶摇摆对蒸发量测量的影响以及如何减小测量用海水与实际海表面海水的温差两个方面做了详细的介绍，并通过试验数据的对比验证，说明了本试验装置具有实用性和推广价值。

Improvement of Measurement Tools of Sea- Surface Evaporation

Evaporation from sea surface is one of the important approaches of mutual relationship between sea and the atmosphere, it is also an important factor of heat energy exchange on the earth. The measurement of evaporation from sea surface plays a very important role in the flux exchange between sea and the atmosphere, but at present domestic measurement instruments are not fit to use in research vessel. In this paper we introduced a kind of ameliorative evaporation measurement tool which is adapted to use in research vessel, mainly introduced how to reduce the influence to the evaporation measurement of shaking of the vessel and how to reduce the temperature difference between seawater for measurement and the actual surface water. We also contrasted the measurement data between the old instrument and the new one, the conclusion is that the measurement tool possesses practicability and value of generalization.
