查询词典 high velocity

The results show that the density of gritstone is decreased gradually as the temperature increasing; so that it can be ignored; the longitudinal wave velocity is linearly decreased when the temperature increasing, and decrease rate of it follows the law of conic; R is one temperature point, which makes the law of tensile strength of gritstone after high temperature follows the law of parabola; and the maximal tensile strength appears when the operative temperature is R. After the temperature is higher than 700 ℃, tensile strength is small and change range is small when the temperature is increased.

结果表明，高温后粗砂岩的密度随试验温度的升高减小幅度很小，几乎可忽略不记；高温后试件中纵波波速的传播随温度升高基本呈线性降低，而减小率呈二次曲线规律变化；存在一个温度点R，使高温后试件的抗拉强度呈开口向下抛物线关系变化，且在R温度作用后试件抗拉强度达到最大；当试验温度大于700 ℃后，试件的抗拉强度变得很小，且当温度升高时变化幅度也很小。
