In this paper, the electric-drive equipment is simplified in order to obtain its working status by computer to dispose the sampling values. AutoCAD is used to draw the circuit diagram of the electric-drive equipment; the further development tool ObjectARX2000 is used to develop the interface program in order to drive the static circuit diagram; the microcontroller is used to sample and transfer the samples to the PC; the Visual Basic is used to construct all the real-time instruction system of the DFll diesel locomotives electric-drive equipment.

本文对东风11的电传动系统进行了适当的简化，使其电路工作状态通过计算机对电压采样值的处理得到确定；用AutoCAD绘制了整个东风11电传动系统的电路图；利用二次开发工具ObjectARX2000开发出接口程序，实现了对AutoCAD所绘制电传动电路图的驱动；用单片机实现了采集装置，并与PC机通讯完成对电路状态的采集；采用VB编程实现了整个东风11型机车的电传动实时教学系统。

Being lack of color matching system for pre-colored wool top blends, it is urgently needed to develop a computer-aided system to help colorists find a good recipe to reproduce a target color. An optimized mathematic model that can be used in computer color matching for wool top blends is set up by using the improved Stearns and Noechel.

针对缺少理想的混色模型现状和开发计算机混色配色系统的迫切需要，在对经验Stearns-Noechel模型优化和改善的基础上建立了适用于毛条混色应用需要的计算机配色预测数学模型。

They think like clerks, talk like clerks, and they approach computer programming and systems analysis with all the enthusiasm of a sleepy civil service clerk who knows that hes just one year away from retirement.having met some twenty-five thousand analysts, designers, and programmers throughout the world, i found a surprising number of them have never read any computer articles or even opened a copy of datamation or computerworld; have never heard of acm, dpma, ieee, asm, or any other professional organizations; cant spell dijkstras name and probably have never heard of him; arent aware of the structured techniques and wouldnt be interested if somebody showed them.

他们象文职人员一样思考、交谈，他们与所有积极的，但昏昏欲睡的知道自己还有一年就退休的文职服务人员一起处理计算机编程和系统分析。已经遇到过整个世界的25000个分析员、设计员及程序，我很吃惊的发现他们中的很多从来没有读过任何计算机的文章甚至是公开的datamation或 computerworld的拷贝；没有听说过acm，dpma，ieee，asm，或者是其它任何专业组织；不能拼出dijkstra的名字，可能从来没有听说过他；不清楚结构化技术，即使是有人告诉他们也不感兴趣。

Along with the progress of computer technology and the improvement of people's demand to system, people put more emphasis on whether MIS can support the decisions of the top leaders of an enterprise, as well as more emphasis on whether the external info-collection, integrated database, model library, arithmetic base, and other artificial intelligent tools of the enterprise can face to the deciders directly, this is the mansion of Decision Support System.

随着计算机技术的进步和人们对系统的需求进一步提高，人们更加强调管理系统能否支持企业高层领导的决策这一功能，更侧重与企业外部信息的收集、综合数据库、模型库、方法库和其他人工智能工具能否直接面向决策者，这是决策支持系统（DDS，Decision Support System）的任务。

Based on system analysis and study of the present design proce- dures of highway width,the paper proposes a set of computer block diagrams for opitimun design of four-lane highway width,By the curvature radius of comber Line of the highway,given in overall design,and related characteristic parameter of the largest vehicle to be allowed to pass through.it is easy for design technicians to complete optimizing design of the lane width with the help of the computer block diagrams.

在对现行公路宽度设计方法进行系统分析及研究的基础上，本文提出一组四车道公路机功车车道宽度优化设计计算机框图。根据总体设计提供的公路各曲线段中心线曲率半径及允许通行的最大车辆的有关特性参数，公路工程设计人员很易通过该组计算机框图圆满地完成四车道公路机动车车道宽度的优化设计工作。
