Water has a variable coefficient of expansion. 水的膨胀系数是可变的。
The thermostat is based on the fact that different metals have different coefficients of expansion. 恒温器是以不同的金属有不同的膨胀系数这一事实为根据的。
After analysis,we earn the conclusion that expansive force of Gypsum Breccia in complete expansion method is bigger than that in balance load method. 试样密度与含水率对膏溶角砾岩轴向膨胀率起决定作用。
