精彩书摘

Unfortunately, often what is manufactured by a company using the over-the-wall process is not what the customer had in mind. This is because of the manyweaknesses in this product development process. First, marketing may not be ableto communicate to engineering a clear picture of what the customers want. Sincethe design engineers have no contact with the customers and limited communi-cation with marketing, there is much room for poor understanding of the designproblem. Second, design engineers do not know as much about the manufacturingprocesses as manufacturing specialists, and therefore some parts may not be ableto be manufactured as drawn or manufactured on existing equipment. Further,manufacturing experts may know less-expensive methods to produce the prod-uct. Thus, this single-direction over-the-wall approach is inefficient and costlyand may result in poor-quality products. Although many companies still use thismethod, most are realizing its weaknesses and are moving away from its use.In the late 1970s and early 1980s, the concept of simultaneous engineeringbegan to break down the walls. This philosophy emphasized the simultaneousdevelopment of the manufacturing process with the evolution of the product.Simultaneous engineering was accomplished by assigning manufacturing repre-sentatives to be members of design teams so that they could interact with thedesign engineers throughout the design process. The goal was the simultaneousdevelopment of the product and the manufacturing process.

前言/序言

　　机械工业出版社在2006年出版了美国大卫G·乌尔曼（David G.Ullman）所著《机械设计过程》第3版的中文翻译本，几年以后我们又见到了该书英文原版的第4版，这一版在保留原有特色的基础上有了较大的改进，反映了机械设计近年来的一些重要的发展和研究成果。
　　本书明确提出了“产品设计”的设计原理，是针对产品设计的设计思想、理论、技术和方法的总结，而对于那些针对“机构”和“零件结构”的设计手段，只作为基础知识介绍。同时，本书全面、具体地给出了“设计学”的基本内容，详细地引出了设计的典型步骤，每一个步骤的任务和目标，应考虑的主要问题和常用的解决方法，对产品设计具有很好的指导作用。本书的主要特点是：
　　1.针对各章节知识点给出了计算机设计用的表格，供设计者参考。
　　2.给出了更多的设计实例和照片。
　　3.各章前面给出了“要点问题”（Keyquestions），使读者阅读时目标更加明确。
　　4.更新了参考资料，使本书更加实用。

第八、九章是第四个单元。方鸿渐和孙柔嘉在返回上海途中结了婚。这对双方来说，都不能算做令人激动的结合，加以失业造成的对于前途的焦虑，使他们婚后不断发生争吵。这种争吵在返沪途中还较为单纯，定居上海后，由于双方家庭和亲族的介入，矛盾更复杂了；在婆媳、翁婿、妯娌、亲朋、乃至主仆之间，一度曾发生了一系列龃龉和纠纷。最后，方、孙的矛盾终因前者辞去报馆资料室主任而面临再次失业时激化了。方鸿渐刚刚建立起来的新家解体，他再次冲出一个“围城”，又来到一个“围城”的入口──他打算投奔在重庆当官的赵辛楣谋取职业，这肯定也是一条前途未卜的坎坷不平的道路。小说在一阵老式自鸣钟的“当、当……”声中结束。像过去一切杰出的现实主义作品一样，它没有提供什么关于社会和人生出路的明确结论，但他描写的生活本身，“深于一切语言，一切啼笑”。

本来就是英文原版的，结果非要把封皮翻译过来，我能说我被误导买错了吗。
