1、热膨胀系数(Coefficient of thermal expansion,簡稱 CTE 是指物质在热胀冷缩效应作用之下,几何特性随着温度的变化而发生变化 的规律性系数。实际应用中,有两种主要的热膨胀系数,分別是:线性热膨胀系数:体积热膨胀系数:1 LL T1VV。Tp大多数情况之下,此系数为正值。也就是说温度升高体积扩大。但是 也有例外,当水在...
The thermal expansion coefficient of Y-α′-sialon depended on the composition, being minimum at x=0.3 in the formula Y x (Si 12-4.5x , Al 4.5x )(O 1.5x , N 16-1.5x ). The coefficient of β′-sialon increased with increasing lattice constant, that is, the z value in the ...
