thermal volume change

基本解释

The thermal stress: the temperature stress changes in heat bilges cold shrink, cause the layer structure of the volume change, and always in a stable state.
热应力：由温度应力变化导致的热胀冷缩，会引起非结构层的体积变化，从而使之始终处于一种不稳定的状态。
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。
