Based on it, the elastic wave velocity spatial distribution around a cased hole in tectonic stressfield is studied by applying the velocity-stress formula of equivalent medium model.
在此基础之上，应用等效介质模型的速度—应力关系式，研究了地应力场中套管井周弹性波速的空间分布规律。

It is found that the distribution of temperature field in roll shell is just like a stressfield following Saint-Venant principle in elastic mechanics.
发现辊套温度场分布规律与弹性力学中的应力场分布遵循圣维南原理相似。
