1·The difference not only consist in the softness (or hardness) of the padding, but also in the size of the cabin or the number of seats in a car.

这其中的区别不仅仅在于乘坐物的软硬，还包括车厢的尺寸或者座位的数量。

2·A good procedure to follow is to heat-quench a number of small specimens of the steel at various temperatures and observe the result, either by hardness testing or by microscopic examination.

要遵循的合适步骤是将这种钢的一些小试件加热到不同的温度后淬火，再通过硬度试验或显微镜检查观测结果。

3·No discoloring, swelling, blisters or film loss; Hardness reduced by one lead number maximum.

无偏色，隆起，起泡或涂膜脱落；硬度降低值不低于一个铅号码。

4·Changing the number of the teeth of a pinion gear or the hardness of the surface of tooth and other parameters, the different results will be gained.

只要改变小齿轮齿数或齿轮齿面硬度及相应的有关参数，可得到齿轮传动计算的不同结果。

5·The quenching layer with high hardness on the surface of number control machine-tools axle was obtained using laser surface treatment technology.

采用激光表面处理工艺，对数控机床主轴主要表面进行快速激光扫描，可获得高硬度的淬火硬化层。

6·The microhardness increases first and then remains at a certain level with the increasing passes, while the route effects on hardness are related to the pass number and the refinement effects.

随挤压次数增加，硬度先增大后保持基本不变，而挤压路径对硬度的影响与挤压次数、挤压后细化效果密切相关。

7·A good procedure to follow is to heat-quench a number of small specimens of the steel at various temperatures and observe the results, either by hardness testing or by microscopic examination.

遵循的一个较好的步骤为：将该钢的许多小试样分别在各种不同的温度下进行加热淬火并观察其试验结果，进行硬度试验或者金相检验。

8·All my friends want to increase access to safe hardness and methods to extend the time, so the internal market, the emergence of a large number of drugs and drugs for external use.

所有朋友都希望获得安全的增加硬度和延长时间的方法，所以市场涌现大批的内服药物和外用药物。
