The housing has a higher coefficient of expansion than the ring . 壳体比圆环具有较高的膨胀系数。
A study on thermal coefficient of expansion for fiber composite material 光声法测量材料热膨胀系数的实验研究
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。
3 it has a precision through and the coefficient of expansion has been calculated accurately , so it is very smooth , bright and clean 3 、精密卡标企口轨道设计,并经准确计算膨胀系数,平整光洁。
A bimetallic strip formed by joining together two metal strips with different coefficients of expansion suffers bending deformation when the temperature changes 双金属条由两条膨胀系数不同的金属条连接而成,它们在温度变化时产生弯曲变形。
