The determination of the hardness value from the auxiliary quantity by employing the relevant equation defining the hardness testing method 透过界定硬度测试法的有关方程式，从辅助数量测定硬度值。
《 international circulation 》 : compare with the bp - lowering evaluation with brachial blood pressure or with the arterial hardness value 《国际循环》 ：比较用肱动脉血压和动脉硬度值来衡量降压效果。
An bh arrow hitting left of fp ' s is a stiff spine reaction if i remember right , so i don ' t think spine is the problem 如果我没记错的话,刀片相对于子弹头偏左,才会关及箭的硬度问题,所以跟硬度值应该没有关系
After taking the d1 ( d2 ) from eyepiece micrometer and entering them , the hardness value is displayed on lcd and the data can be printed out 输入用测微目镜测得的对角线长度,即在lcd上显示硬度值。可打印记录。

4 . after heat treatment ni - w - b alloy was both coarsened in grain size and led to the evolution of ni4w and precipitation of ni - b compound Ni w b合金电沉积层及其复合镀层的显微硬度值比ni w合金电沉积层的显微硬度高。
The results shows that the failure parts has high silicon content and uneven hardness , the impact toughness and elongation is far below the specification of the material 结果发现，失效件的硅含量偏高、硬度值很不均匀，冲击韧度和伸长率远低于材质要求，因而导致脆断。
The change of the micro - hardness along the radial direction approximately coincides with the exponential decay , that is at the edge of the crater the hardness is the highest and decreases with the increase of the distance from the crater and to the normal value at last 弹孔侧壁硬度的径向分布近似符合负指数规律，即在紧邻侧壁处，材料因剧烈变形而强化，随到侧壁距离的增加，硬度值降低，直至降到基体材料硬度水平。
