闭合

It turns out that crack closure is the main reason for retardation, and crack tip blunting, crack deflection and strain-induced martensite would reinforce it.

室温蠕变对裂纹扩展产生延滞的原因主要是裂纹闭合，同时裂尖钝化、裂纹偏折及形变诱发马氏体的形成也会起到一定的作用。

A new algorithm for representing conies precisely is presented using the periodic NURBS. The algorithm requires only four control vertices to represent a full circle using a circumscribing square.
