434 We shall take the sample to test its physical properties (mechanical properties, t ensile strength, yield point, percentage elongation, reduction of area, impact value, Brinell hardness).

我们将取样试验其物理性能（机械性能、抗张强度、屈服点、延伸率、断面收缩率、冲击值、布氏硬度）。

The Brinell Hardness test that largest indentment among all the hardness tests ia able to reflect the comprehensive features of the material,and the test is unaffected by the organization micro-dioptre and the compositional unevenness of the speciment;and hence it is a hardness testing with high precision.

该款硬度计外形设计上美观大方，有使用简单方便，免计算查表等特点方便了广大用户的使用。布氏硬度试验是所有硬度试验中压痕最大的一种试验法，它能反映出材料的综合性能，不受试样组织显微偏析及成分不均匀的影响，所以它是一种精度较高的硬度试验法。

The hardness of carburized and subsequently quenched parts will be dependent on the carbon concentration in carburized case. Based on experimental data, variation of the

根据试验数据建立了马氏体含碳量与硬度的函数关系，预测了圆柱形工件渗碳后的碳浓度布和淬火后的硬度，硬度的预测结果与试验结果相吻合。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
