| 摘 要： | 在应用秋田谷式含水率计测量湿雪含水率的过程中，雪样被短时间暴露在通常为正温的环境中产生融化，人而带来量测值的误差，通过试验，建立标准操作时间，然后利用大量的野外雪水分离及含水率量测资料，得出气温对含水率测定值影响的定量关系，测定值的气温（T，℃）订正值为-0.37T(T≥0)。 |

| Abstract: | This paper deals with the quantitative impact of ai rtem perature on the measured water content value of wet snow by Akitaya calorimeter. Based on the pre-experiments,a set of operating standards was determined. Upon the standards, large amounts of snow(grains)-water separation and snow water co n tent measurement were conducted in the field. By regression, it is found that a correct water content value is obtained by subtracting 0.37T(T:air temperatu re,≥0) from the measured value. |
