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,从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).
This paper deals with the quantitative impact of air temperature 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 content 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 temperature,≥0) from the measured value.
