整段翻译1. Worker are encouraged to correct their own error, and 100% inspection is the rule. passing defective products on to the next process is not allowed. the goal is perfection. quality circle, now popular in the U.S, are just one of the methods used by Japanese industries to achieve perfection. Basically, inspect of products can be done by attributes and by variable. every part must be made accurately, within specified limits, to the size and shape specified by the designer.公司鼓励工人自我纠正差错…….鼓励工人来纠正自己的错误，和100％检验规则。
传递到下一个过程中的有缺陷的产品是不允许的。
我们的目标是完美的。
品质圈，在美国，现在流行的是由日本产业实现完美的方法之一。
基本上，检查的产品，可以通过属性和变量。
的每一个部分都必须准确地，在指定的范围内，由设计者指定的大小和形状。
2. The feeding and threading mechanism consists of a quick –change gearbox, a lead screw, a feed rod , and gears and clutches in the apron. The quick-change gearbox is located directly below the headstock assembly. Power from the left end of the spindle is transmit-ted through gears to the quick-change gearbox. This gear box contains a number of different-sized gears.Usually two or three levers must be moved to obtain the correct feed or the correct number of threads per inch. An index chart or plate is attached to the front of the gearbox and indicates the position of the lever for obtaining the desired feed or threads per inch. The lead screw and feed rod transmit the carriage for operating the automatic feed and for thread cutting.进给及车螺纹机构包括快速更换变速箱，丝杠，饲料杆，齿轮和离合器在停机坪。
快速更换变速箱正下方启闭组件。
通过快速更换变速箱齿轮的主轴从左端是电源传输。
该齿轮箱包含若干不同大小的齿轮。
一般两个或三个杠杆必须移动，以获得正确的饲料或每英寸螺纹的正确数量。
一个索引图或板被连接到齿轮箱的前面，表示操作杆的位置，用于获得所需的饲料或每英寸螺纹。
导螺杆和输送杆的发送操作的自动进给和螺纹切削的滑架。
句字翻译1. A motor-driven headstock and a tailstock are mounted on the left and right ends, respectively, of the swivel table for holding workpieces on center. The headstock center on a grinder is dead center;that is ,both centers are”dead”to insure concentricity of the periphery of ground work withits axis.1.由电动机驱动的头架和尾架分别装在可偏转的工作台的左右侧,以便在顶尖间夹持工件.磨床头架的顶尖也是死顶尖,即两个顶尖均为死顶尖,这样可保证被磨削工件的轴线与其外圆的同轴度.2.Equally important, engineers must be concerned about the safety and health of others,the environment, and the social implications of the solution they provide. The engineer must work for and with people, as well as things.2同样重要的是,工程师必须关心他人的安全健康和环境以及他们提供的解决办法的社会效应.工程师即为人工作,又要能和人一起工作,适应周围的事物.3. mechanical design means the design of the things and systems of a mechanical nature-machines, products, structures, devices, and instruments. For the most part, mechanical design utilizes mathematics, the materials sciences, and the engineering-mechanicals sciences.3机械设计就是机械性质的用品和系统(及机器产品结构装置及仪表等)的设计.在很大程度上,机械设计运用数学材料科学及工程力学的知识.4An elastic material is one that can be deformed and then return to its original shape when the load is removed . elasticity involves the relationship between stress and strain.4弹性体就是受力会变形当力去掉后又恢复原状材料.弹性意指应力与应变间的关系.5Elasticity is expressed by Hooker”s Law as the degree to which an elastic body bends or stretches out of shape (strain) which is in direct proportion to the force (stress)acting upon it.5朔性就是允许金属在超出弹性极限后产生永久变形而不会断裂或破裂而失效的特性.6Plasticity is the property that allows metals to be permanently deformed beyond the elastic limit without failure by rupture or splitting.6延展性(可锻性)就是金属受载荷压缩时产生永久变形的能力.7Hardening is the process of heating a piece of steel to a temperature within or above its critical range and then cooling it rapidly.7淬火就是将钢件加热到它的临界温度上下然后快速冷却的一种加速过程8By tempering or drawing the hardness and brittleness may be reduced to the desired point for service conditions.8通过回火可将硬度和脆性降到工作条件所需要的程度9Spur gears are used to transmit rotary motion between parallel shaft; they are usually cylindricalin shape, and the teeth are straight and parallel to the axis of rotation.9直齿轮用于传递平行轴间的旋转运动。
它们一般为圆柱形，其轮齿为直线而且平行于旋转轴线。
