(which in turn can be fastened onto the two shafts by means of setscrews or other fasteners ． ( 通过定位螺钉或其他紧固件将其固定在 两个轴上。 ) 5.Brittle materials have high compressive strength but only a moderate tensile strength ． ( 脆性材料抗压强度较高，抗拉强度只有中等水平。 ) 三．英汉互译 1.Themain components of the lathe are the headstock and tailstock at opposite ends of a bed ， and a tool post between them which holds the cutting too1 ． ( 车床的主要部件是主轴箱、尾座和刀架，主轴箱与尾座位于床身的两端，用于夹持刀具的刀架置于主轴箱与尾座之间。 ) 2.If a hard grade wheel was to be used for grinding a hard material ， the dull grains would not be pulled off from the bond quickly enough ， thus impeding the self dressing process of the surface of the wheel and finally resulting in clogging of the wheel and burns on the ground surface ． ( 如果使用硬砂轮磨削硬的材料，磨钝的磨粒就不能很快从粘结体上脱落，这样便妨碍砂轮表面的自休整过程，最终导致砂轮的堵塞并在被磨表面留下灼斑。 ) 3.This soft silvergray metal could be converted into a superhard substance that could cut glass and many other substances, including itself when soft ． ( 这种银灰色的软金属可以转换成一种超硬的物质，该物质可以切削玻璃和许多其他物质，包括处于软状态的该物质本身。 ) 4，which is usually negligible in conventional finish grinding and creep feed grinding. The grinding tem- perature at the finish surface can be much lower than that at the wheel–work contact surface, owing这在常规的精磨和缓进给磨削中，通常是忽略的。由于在工件内相对较小的热渗透深度和不断去除的磨削碎片，在完成表面的磨削温度可以大大低于砂轮－加工接触面处The partitioning of the
