应用稳定态的比较法，测定了不同总含水量、不同土中溶液浓度的冻结兰州砂土、兰州黄土的导热系数，同时应用量热法测定了土骨架和纯氯化钠在同一负温下的比热，并据此计算了土的导温系数。结果显示，在同一负温下各种土质的比热均随含盐量的增加而增大，兰州砂土的导热系数和导温系数随含盐量的增大而降低，而兰州黄土的这两个参数随含盐量从零开始增加，首先增大，在土中溶液初始浓度约为５％时，达到最大值，接着逐渐减小。
The steady state comparison method was used to determine the thermal conductivity of frozen Lanzhou sand and Lanzhou loess with different total water content and solution concentration in different soils. At the same time, the thermal conductivity of soil skeleton and pure sodium chloride at the same negative temperature Of the specific heat, and thus calculate the soil temperature coefficient. The results showed that the specific heat of various soil types increased with the increase of salinity under the same negative temperature. The thermal conductivity and the temperature coefficient of Lanzhou sand decreased with the increase of salinity, while the Lanzhou loess With the increase of salinity from zero, the two parameters first increase, reach the maximum when the initial concentration of solution in soil is about 5%, and then decrease gradually.
