The roll separating force, rolling torque and contact pressure along the surface of the rolls are also evaluated by means of the finite element method.

轧制分离力、轧制力矩以及沿轧辊表面的接触压力也通过有限元法进行评估。

The experimental result also shows that the nitrogen element on the surface of contact black surface may be mainly in forms of amino group and nitro group.

此外，实验分析了接触法炭黑表面氮元素的组成，结果表明主要是以氨基和硝基的形式存在。

In the paper, the dam seepage analysis is conducted with no depth contact interface element to simulate layer surface.

本文采用无厚度的接触界面单元模拟层面，进行了坝体的渗流分析。
