Concurrent Engineering absorbs computer technique , database technique , network technique under the support of CAD, CAM, CAPP and CAE, considers conception form , scheme analyses , detail design, production, after service , production rejects all factors, resolves effetely lots of defects such as difficulty of data exchange , design changing frequently , cost high, long cycle for design and so on.

摘要并行工程是在CAD，CAM，CAPP和CAE等技术支持下，吸收了当前迅速发展的计算机技术、数据库技术、网络技术，在设计时综合考虑产品开发中的概念形成、方案分析、详细设计、生产制造、售后服务、产品报废等所有因素，有效解决了系统之间数据交换难，设计更改频繁，成本高，设计周期长等缺点。 DFM是并行工程的关键技术之一，在设计一开始就把制造系统的因素添加到设计过程中去，并从制造可行性的角度对设计进行分析评价，使设计满足制造要求，降低加工时间和生产成本。

There are many ways to analysis and computation of Mikthw's two rotations equation,finite difference method is the most one while using the finite difference method,a flood of data need be collected and computed.

而在目前高性能计算机系统中，最广泛使用的并行环境是MPI(Message Pass-ing Interface)，它已成为一种并行程序的标准。

The contradiction between the finiteness of single computer's technology development and the infiniteness of the requirement for science computing determines that multi-computer's parallel will be the development of computer.

计算机单机技术发展的有限性和科学工程计算需求的无限性，决定了计算机的发展必然走上多机并行的道路。

After the tested N gas components are led into the spectrograph via sampling probe and pipeline, the spectrograph obtains the transmittivity data in the scanned wave number or wavelength range and transmits the data to the computer, the computer extracts the effective characteristic quantities as the input to the parallel supporting vector machine algorithm module, and the supporting vector machine outputs the multiple component gas concentration values.

被测的N个多组分气体经气体采样探头与连接管路导入光谱仪，由光谱仪获得扫描波数或波长范围内各波数或波长对应的透射率关系给出光谱数据经数据传输线进入计算机。进入计算机内的光谱数据由软件的数据预处理模块提取有效的特征量，作为支持向量机并行算法模块的输入，支持向量机并行算法模块的输出为N个多组分气体浓度。

The work has been emulated and analyzed by computers, and a computer network fault diagnosis system has been excogitated.

在BP神经网络算法上对LM算法进行改进，对在LM算法中的大型矩阵求逆时使用并行算法求解线性方程组的方式加以改进，并使用计算机网络故障诊断作为实际算例进行计算机仿真和分析，开发了一套计算机网络诊断系统，以期能对理论研究和应用工作提供参考和帮助。

For the paralleling computation of simulation this paper gives the method to do it on the cluster system.

在微观仿真自身的并行计算方面，本文提出了在计算机集群系统上开展城市交通微观仿真并行计算的思想。

Now there are many kinds of implantation products with various brands. Most of them are serial ones, which cannot meet the needs of the persons with skeleton deformity or abnormal injured skeleton parts. And because of the long time of design and manufacturing, economical efficiency and other reasons, customized orthopaedics products applied in clinic are limited. It's urgent to reduce the time of design and manufacturing on the base of costcutting, so the parallel computing will bring its power into play.

目前，骨科植入物产品种类繁多，各种品牌层出不穷，系列化产品占据了市场的绝大部分份额，而往往有相当部分病人由于骨骼畸形或伤及少见的骨骼生理部位，系列化产品很难满足要求，又由于因人而异的骨科产品受其设计与加工的时间、精力、财力等许多方面制约而变得应用寥寥，在降低成本的基础上如何减少设计与加工周期将变得十分迫切，并行计算将在此处有一席用武之地；另外计算机辅助手术也将在这领域逐步推广，尤其在术中阶段，系统对并行计算的需求尤为迫切。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
