摘要： Babin模型是目前理论上很先进的一种蒸发波导诊断模型，为提高该模型的使用效果，对该模型进行了理论推导，并仿真分析了模型对输入参数的敏感性。研究结果表明：不稳定层结条件下，模型对相对湿度最敏感，而稳定和中性层结条件下，模型对海表温度最敏感，而大气压力的扰动对该模型诊断结果几乎没有什么影响。在利用海表面测量参数诊断蒸发波导时，应选用精度较高的相对湿度和海表温度传感器。

Abstract: Babin model is an advanced method of evaporation waveguide diagnosis, to improve the effect of this model, the formulas is deduced , and the sensitivity of its inputting parameters is analysed with the method of simulation, the research shows that the relative humidity is the most sensitive parameter in condition of unstable atmospheric layer, and surface temperature is the most sensitive parameter in condition of stable and neutral atmospheric layer, and the turbulence of air pressure is almost no effect on the calculation result. High precision sensors of relative humidity and surface temperature should be selected when evaporation vaveguide is diagnosed from the parameters measured above the surface.

Key words: Evaporation, Waveguide, Babin model, Measurement error
