【摘要】 根据实测资料,采用算术平均法和相关分析法分析计算了伊犁河干流区雅马渡站的20cm口径小型蒸发器与E 601型的水面蒸发折算系数。通过对计算的水面蒸发折算系数的误差分析和检验,表明折算系数的计算精度较高,为有效利用长系列20cm口径小型蒸发器资料提供了科学的依据。更多还原

【Abstract】 Based on the data observed from the Yamadu Hydrometric Station in Ili River trunk, adopting the average method and correlative method to analyze the evaporation reduction coefficient of small evaporation pan and E-601 type, and analysing error examinations. The result shows that computation accuracy is better. It provided a scientific basis for using the small evaporation pan data of long series.更多还原
