5、In order to be able to apply the principles to commercial working process,we require answers to two main questions. 为了能使这些原理应用于商品加工过程中，有两个主要问题需要解决
6、The dynamic structural changes leave the metal in an unstable state and provide the driving force for static recovery and static recrystallization to take place after the deformation pass. 这些动态的结构变化使金属处于不稳定状态并为变形后的静态回复和静态再结晶提供了驱动力
三角函数公式高中7、The parameter which is commonly lected as a measure of superplastic formability is the tensile elongation at the optimum superplastic temperature and strain rate. 通常选来度量超塑成形性的参数是在最佳超塑性温度和应变速率下的伸长率
第四章
1、It is often only possible to achieve a general shape;the final part to drawing must be created by subquent hand work;springback is a problem with high strength materials.
通常只能获得一个大体形状，最后要拉深的部分必须用手工操作来完成，高强度材料的回弹也是一个问题
2、An interesting variation on rubber forming was developed for the manufacture of small foil containers,which generally buckle very easily in walls during manufacture. 另外一种令人感兴趣的用来生产小型薄壁容器的橡胶成形方法开发出来了 ，这种容器的壁部在生产过程中一般很容易起皱
3、A circular sheet metal blank is rotated in a lathe and a manually operated tool deflects it against a rotating former until the required shape is produced. 一块圆形金属板料由车床带着旋转，人工操作的工具抵着旋转的模型使之变形，直至形成所需要的形状
4、Additionally,the process is very flexible and blanks from 5 mm to 5 m in diameter and from 0.5 mm to 30 mm in thickness are spun with simple mechanical aids. 此外，这种工艺适应性强，直径从5mm到5m，厚度从0.5mm到30mm的坯料在简单机械的辅助下都可以旋压
5、It is clear that this is a low production rate process and it is ud today predominantly in the aircraft industry for simple forming of high strength aluminum alloys. 显然，这是一种低生产率的工艺，现在只要用于航空工业中高强度铝合金的简单成形
6、There is some difference in design of dies for different metals;copper-alloy forgings can be made with less draft than steel,conquently more complicated shapes can be produced. 不同金属成形模具的设计有所不同，铜合金锻件锻造时遇到的阻力比钢锻件遇到的小，因此可以生产更复杂的锻件
7、In the final forging it is important not to have the steel too hot,for an overheated steel with have poor mechanical properties when cooled. 在精锻过程中，不要使钢坯过热很重要，因为过热的钢坯冷却后会使机械性能变差
香菇素第五章
1、Like charges repel;unlike attract. 同种电荷相斥，异种电荷相吸
什么是oa系统2、In normal cas the lower half is fitted to the table of the press and the upper half to th
e ram. 通常把模具的下半部分安装在工作台上，下半部分安装在锤头上
怎样给仓鼠洗澡3、The cutoff frequency of the varactor is a fundamental obstacle to wide-range electronic tuning at X band at least. 变容二极管的截止频率是实现宽范围电子调谐的主要障碍，至少在X波段是如此
4、Design parameters,system characteristics and communication abnormalities are significant factors the planner must acknowledge in the structuring of the earth station subsystem. 建造地球站分系统时，设计参数、系统特性和通信的反常现象是系统设计人员必须考虑的三个重要因素
5、A compression mold basically consists of an upper and a lower part. 压膜基本上由上模和下模两部分组成
6、Note again that considerable simplication in solving the above can be achieve if the data is made symmetrical. 还要注意，在解决上述问题时，如果使数据对称，就能得到很大程度的简化
