Manufacturing information construction basically insures its durative development. Computer Aided Process Planning is the bridge that joint Computer Aided Design and Computer Aided Make. CAPP system is only transition-layer where the product construction information in CAD is sent to CAM system to become process information. At the same time, the output of CAPP system is important origin of Management Information System and important foundation of Process Planning System.

Physical model of computer box is established and through analyzing the changing curves of change of electromagnetic field with time and change of coupling coefficient with frequency, the coupling regulation of electromagnetic on computer box is obtained. It is as follows: electromagnetic pulse has a great effect on components of computer box through apertures and slots, the coupling energy in the box increases first and then decreases. The existence of components decreases the shielding effectiveness and resonant frequency.

建立计算机机箱的物理模型，通过分析机箱内的电磁场随时间的变化曲线和耦合系数随频率的变化曲线，得到电磁脉冲对计算机机箱的耦合规律：电磁脉冲可以通过孔缝进入机箱内部，对机箱内元件的瞬间影响较大；机箱内的耦合能量是先增加后减小；元件的存在使得机箱的屏蔽效能降低，谐振频率下降。

A daisy chain (in which all computers are connected to two others in one chain) uses the minimum of cables, but the relative speed of the connections is smaller, because if the computer on one end tries to send a signal to a computer at the other end, it must first go through every computer in between.

一个菊花链（其中所有的计算机都通过一个链条与其它两台相连）用的线缆最少，但相对来说速度有限，因为一端的一台计算机如果需要给另一端的计算机发去一个信号，首先需要经过它们之间的每一台计算机。

Computer science known as the computer, by the early development of the electric calculator. In 1946, there have been the world's first electronic digital computer "ENIAC", used to calculate the trajectory.

电脑的学名为电子计算机，是由早期的电动计算器发展而来的。1946年，世界上出现了第一台电子数字计算机&ENIAC&，用于计算弹道。

Mold manufacturing cost is high, demand manufacturing cycle is short, and strong technical characteristics, at present, along with the continuous development of science and technology and computer applications, these problems have been greatly improved, thanks to computer-aided design and computer-aided machining , and fundamentally change the face of the mold and reliably guarantee the accuracy of the mold needs and quality of pre-hardened, easy-cutting and high brightness and so on, the new mold material applications, which will greatly facilitate the processing and heat treatment.

模具制造业存在成本高，要求制造周期短，技术性强等特点，目前，随着科学技术的不断发展和计算机的应用，这些问题得到了很大的改善，由于有了计算机辅助设计和计算机辅助加工，从根本上改变了模具生产的面貌，可靠地保证了模具所需要的精度与质量、预硬、易切削以及高光亮等，新型模具材料的应用，大大地方便了加工及热处理。

The gladdest thing is to be mixed on Saturday go to Harbin shipping institute on Sunday the computer around a street, endure door city to enter, watch computer, see a family install a machine, I recommend the boss that sees computer company actively oneself, communicate with them, the purpose has only, hope the boss won't drive me to go namely, I can stay a little while more over him, look a little while more, the time that mix grew, the boss also trusted, some moment also let my help maintain monitor, power source closes, with a few breakdown of board card, work did not work less, the knowledge that learns me is used.

最兴奋的事情是星期六和星期天去哈尔滨船舶学院四周的电脑一条街，挨家门市进，看看电脑，看看人家安装机器，看到电脑公司的老板我主动推荐自己，和他们交流，目的只有一个，就是希望老板不会赶我走，我可以在他那里多呆一会儿，多看一会儿，混的时间长了，老板也就信任了，有的时候也让我帮助维修一下显示器，电源合，和一些板卡的故障，活儿没少干，把我学的知识都用上了。

The statistic results show that the cost of experiments doubled every ten years because the price of the laboratory apparatus and the cost of labor force increase. On the other hand, the cost of computer simulation decreases due to the improvements of the computer hardware and software technology. Thus more and more researchers focus their interests on the technology of computer simulation.

近年来随着实验仪器、劳动力成本的增加，人们做实验的花费也随之成倍增长，据估计每过十年实验的成本就要翻一番，另一方面，采用计算机来模拟实际体系的成本却随着计算机硬件和软件技术的进步而不断下降，因此分子模拟技术越来越受到相关领域研究人员的关注。
