The test data show that for loess with constant water content, if the density is increased, the coefficient of thermal conductivity and specific volume heat both are increased.

实验结果揭示出，在含水量一定的情况下，导热系数和比热容随密度增大而增大；在密度相同的情况下，导热系数和比热容亦随含水量的增大而增大。

After that it is pointed out that compared with soil density changes, water content change can result in more variations of coefficient of thermal conductivity and specific volume heat of loess.

相对于随密度的变化，黄土导热系数和比热容随含水量的变化尤为显著，含水量变化可以引起热参数较大的变化。
