Today’s industries cannot survive worldwide competitionunless they introduce new products with better quality(quality,Q), at lower cost(cost, C), and with shorter timedelivery(delivery, D).除非能以较低的价格提供更好的质量及更短的交货时间提供新产品,否则任何企业都无法在当今的国际竞争中立足。

2. The design process starts from customers’ demands that areidentified by marketing personnel and ends with a completedescription of the product, usually in the form of a drawing. 设计过程始于由市场人员认定的用户需求,止于对产品的完整描述,通常用图形来表现。

3. The activities involved in the design process can be classifiedlargely as two types: synthesis and analysis.设计过程所涉及的活动大体分为两类:综合和分析4. An analysis model is derived first because the analysis subprocess is applied to the model rather than the design itself 首先要导出一个分析模型,因为分析子过程适用于该模型而非设计本身。

5.As illustrated in Fig1.1, the manufacturing process begins with process planning, using the drawings from the design process, and it ends with the actual products.如图1.1所示,制造过程根据设计过程的图纸始于工艺计划,止于实际的产品。

第二单元第25页1. The purpose of this system is to acquire information fromsuitable transducers about the behavior of some physicalsystem and to display this information to the observer.测量系统的目的是从相应的传感器上获取某个系统的性能变化的数据,并向观测员显示该数据。

2. In measurement system, therefore, one expects to beconcerned with locating and removing any small errors thatmight be added to the signal at each step of the processingsequence.在测量系统中,每一个处理步骤都会将预计到的涉及查找和消除的任何小错误,添加到的信号上。

3. The third system is the feedback control system, in whichinformation about the behavior of the output modifies thesignals driving the system.第三个系统是反馈控制系统,在该系统中,通过输出性能的数据来调整驱动系统的信号。

4. This familiar example, which in fact includes no electricalcomponents other than a switch, was chosen to emphasize thefeedback concept.事实上,我们选择了一个熟悉的反馈系统的例子(就是只有一个开关而没有任何电器元件)来强调反馈原理。

5. Suppose there were no mechanism for turning the furnace ON or OFF, the temperature of the room would either rise to some maximum or drop to some minimum.假设熔炉没有开关装置,房间的温度,或者升到最高某个温度,或者降到最低的某个温度。
