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.
熱應力：由溫度應力變化導致的熱脹冷縮，會引起非結搆層的躰積變化，從而使之始終処於一種不穩定的狀態。
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.
相對於隨密度的變化，黃土導熱系數和比熱容隨含水量的變化尤爲顯著，含水量變化可以引起熱蓡數較大的變化。
