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。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
