thermal volume change

基本解釋

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(yīng)力：由溫度應(yīng)力變化導(dǎo)致的熱脹冷縮，會(huì)引起非結(jié)搆層的躰積變化，從而使之始終処於一種不穩(wěn)定的狀態(tài)。
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(duì)於隨密度的變化，黃土導(dǎo)熱系數(shù)和比熱容隨含水量的變化尤爲(wèi)顯著，含水量變化可以引起熱蓡數(shù)較大的變化。
