To assure parts' machining precision and to improve productivity, touch probe is used to inspect cylinder of parts on machining centers, thus coordinate of points on features are acquired from numerical control system by a data collecting program, and cylindricity error is calculated by computer. This method has broken the restriction of probe's macro processor that couldn't work out cylindricity error. Data saved in computer are beyond the limited memory of numerical control system, which improves operation speed.

为了保证零件加工精度和提高生产率，在数控加工中心中采用触发式零件检测测头对被加工件的圆柱面进行在机检测，并利用数据读取程序从数控系统内部提取被检测点坐标信息，在计算机内部完成圆柱度误差的计算，克服了零件检测测头自带宏程序无法对圆柱等被测特征进行误差运算的局限性；并且检测数据存储于计算机内，不再受数控系统内存小及运算速度慢的限制。

For the follow-up treatment.Software part want function that realize: Through interrupt service routine gather and come out regularly ECG signal, store among computer in the form of the binary scale; Data compress programme should realize to ECG signal pretreatment and compress of signal, Narrow the storing amount of the data, save the space; Case information management system realize patient information and heart telecommunication file of interest, Keep and in the data base, can show the ECG signal wave form at the screen of the computer directly data that gather. Andhas offered and type and report the single function.

软件部分所要实现的功能为：通过中断服务程序把心电信号定时采集出来，以二进制的形式存储在计算机中；数据压缩程序应实现对心电信号的预处理和压缩，缩小数据存储量，节省空间；病例信息管理系统实现患者个人信息和心电信息的存档，把采集的数据保存作数据库中，能够将心电波形直接显示在计算机屏幕上，并提供打印报告单的功能。

In other words, when a branch in the code the computer was processing occurred (that is, there is an unanticipated call to another section of the program that necessitates another call to memory), instead of stalling the pipeline to retrieve the instructions that were branched to, the computer added a delaying instruction behind the branch that either did something useful while the other instructions were called, or at worst did nothing at all.

换句话说就是，当计算机执行的代码中出现了分支(就是说，发生了不可预料的对程序中其他程序段的调用，即必须实现一个新的访问存储器的操作)时，计算机不是停止这条流水线的工作去修复被分解的指令，而是在这个分支指令后增加一个延迟指令，该指令在其他指令被调用时，要么做一些有用的事情要么执行空操作。

According to the demand of high magnetic field power supply, reference is increased with a set ramp rate and stops at a set stable value, so reference system is composed of digital setting and digit to analog converting circuit. But the stability of reference is mostly guaranteed by the performance of D/A circuit, so D/A circuit is particularly studied in reference system. The scheme of D/A circuit, the selection of DAC and its voltage reference, hardware anti-jamming design and PCB design are discussed in detail, and software of remote control and PLC are discussed in brief. Zero-flux DC current transformer well satisfies the demands of the high stability of Load current detection unit, so the principle of zero-flux DC current transformer is analyzed; in the mean time a project which detects the long term stability is designed. During 8 hours, analog signal which is detected with high precision digit multimeter is recorded in computer at 1HZ frequency by GPIB communication. The drift error source and related parameters are explained in the compare-amplify part. Detailed subtraction circuit is designed; also amplifier chip and periphery components are selected and verified according to the theory of error analysis.

根据强磁场电源的需求，参考源应按照软件设定的斜率逐渐上升到设定稳态值，则参考源系统应由数字给定和数模转换电路两大部分组成，而参考源的稳定度主要依靠完成数模转换功能的模拟电路的性能来保证，因此本文对参考源系统的研究以数模转换电路为重点，分别从电路方案的确定、数模转换芯片及其基准电压源的选取和验证、电路板硬件抗干扰和PCB设计几方面进行了论述，然后对数字给定部分的远控组态和PLC程序设计作了简要介绍；采用零磁通原理的直流电流转换器很好地满足了对负载电流检测单元高稳定度的需求，本文详细分析了零磁通检测的原理，并在选定此种类型电流转换器的基础上设计了一套检测长期稳定度的方案，8小时内以1秒为采样周期，通过计算机Labview程序和高精度数字电压表的GPIB通讯，将被高精度数字电压表数字化后的模拟信号采样值连续记录至计算机中；比较放大环节简要阐述了漂移产生的原因和相关参数指标，确定了具体的减法电路形式，并根据误差分析理论对运算放大器和外围元器件进行了选取和验证。

This program primely adopt the tactics that weaken the action strength of opponent.four corners priority tactics、the most edacity tactics.at the beginning of the game and the middle of the game,the program adopt weaken the action strength of opponent,namely reduce the positionn of the opponent to play the chess mostly;at the end of the game we use the he most edacity tactics,namely to eat up the chess of the opponent to the best of one ' s abilities;the four corners priority tactics is run through the whole game,the four corners of the chessboard are stabilization corner,can ' t eated up by the opponent,so here is the most important position of player to contest,at the same time of prevent opponent to put the chess in the corners of the chessboard,we make great efforts to put the chess in the corners.

本文首先详细介绍了黑白棋的游戏规则，和一些基本的战术，然后将这些战术编写成代码存储在计算机中，使计算机在对弈过程中，可以灵活的运用这些战术。该程序主要运用的战术有削弱对手行动力战术、四角优先战术、最大贪吃战术。在游戏开局和中局时，程序采用削弱对手行动力战术，即尽量减少对手能够落子的位置；在游戏终局时则采用最大贪吃战术，即尽可能多的吃掉对手的棋子；而四角优先战术则是贯穿游戏的始终，棋盘的四角为稳定角，不会被对手吃掉，所以这里是兵家的必争之地，在阻止对手进角的同时，自己却又要努力的进角。

My passion for computers got another strong boost in 1952, when a summer job at IBM in Endicott, New York, gave me hands-on experience in programming the IBM 604 and formal instruction in programming IBM's 701, its first stored-program machine. Graduate school under Aiken and Iverson at Harvard made my career dream a reality, and I was hooked for life.

我对计算机的热情在1952年进一步高涨，因为得到了IBM在纽约恩迪科特的一份暑期工，正是那次，我有了在IBM 604上编程的实际经验，也了解了如何编制IBM 701（它的第一个存储程序计算机）程序的正式指令；从哈佛大学Aiken和Iverson名下毕业终于让我的职业梦想变成了现实，并且，就这样沉迷了一辈子。

Such intermediate programs are then transferred over the Internet into computers where an interpreter program then executes the intermediate form as an application program.

这样的中间程序随后通过因特网传送给计算机，而这些计算机里的解释程序接下来将中间程序作为应用程序来执行。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
