The material stress in rolling contact results from the external loading of a bearing under contact pressure as well as from additional stresses of a mechanical, chemical or thermal nature.

材料的应力在滚动结果从外在负载下的轴承接触压力以及从附加应力的机械、化工或热性质。

Increases the leveling hoop quantity, is eliminated most greatly the material stress, after the leveling, raw material smoothness is more ideal, causes the rate of finished products enhancement.

增加整平滚轮的数量，令材料的应力最大消除，整平后原材料的平坦度更理想，使成品率提高。

That gives the material strength, as there are fewer places for stress to build up and fractures to form than in hydroxyapatite made haphazardly of larger, more heterogeneous grains.
