这是一个改进型计算器克服了浮点运算误差新增了报数和运算符改错功能，比起我上次做的代码质量更高，更简捷，算法也不一样。当前只支持基本的四则运算，非常适用！！！，美中不足是报音慢点，但对于手慢的使用者也足够了，对于大量快速计算建议关闭报数功能。在98上通过-This is an improved version of Calculator overcome the floating-point error in the newspapers a few new and Operators Corrector function, compared to the last time I do a higher quality of code, more simple, not the same algorithm. Currently only supports the four basic operations, very applicable! ! ! , Reportedly fly in the ointment is the sound slow, but for users of hand slow enough for a large number of fast computation reportedly recommended the closure of several functions. Adopted in 1998 下载

《管状换热器计算机辅助设计系统ExhCAD绘图系统(版本:1.01a Final)》为自由软件，采用增量软件开发模型，并用UML对软件进行 建模，以便更新。 该版本只是对换热器的最简单的形式做出设计，而且程序在计算 (包括设计、校核两部分，其中校核部分未编)、绘图过程中都作了简 化，虽然采用了参数化绘图，并能进行简单的数据管理，但没有考虑 换热器的插入件、安装(待编)等因素的影响，特别是在绘图中用 Automatuion技术绘制了管子部分,并对一些常用图形设计了图库，以 方便操作，后采用Object Arx详绘！由于水平和时间、精力等因素，软 件肯定有不少的Bug，但这是我的第一次尝试，希望能得到高手的指点。 设计出的换热器适应于冶金企业中使用，尤其是工业加热炉的余 热回收；以金属直、光管为传热介质，空气在管内流动，烟气在管外 流动。考虑实际情况，大多数换热器采用逆流，按照实际要求，本软 件在设计时做了些简化处理，但仍然能满足工程需要。 配置要求：主机在486以上，操作系统为Windows 98以上。如果要 使用完整功能，则需要装有AutoCAD R14、Microsoft Excel 2000、 Microsoft Access 2000。-"tubular heat exchanger computer-aided design system ExhCAD Mapping System (Version : Final 1.01a)," free software, using incremental software development model, and the UML modeling software to update. The release of heat exchanger is the most simple design made in the form and the procedures in the calculation (including design, verification of two parts, which some non-checking), the mapping process has been simplified, although the parameters of graphics, and simple data management, but did not consider the heat exchanger The inserts, installation (to be ed.), the impact of such factors, especially in the graphics rendering technology used Automatuion the tubes, as well as some commonly used graphics library designed to facilitate the operation, after using Object Arx detaile 下载

随着Windows98的推出，越来越多的微机用户已习惯于Windows操作系统。不过Windows应用软件的开发对于一般工程技术领域的技术人员来说并非易事，然而使用微软的VisualBasic6.0（简称VB6）来开发这些方面的Windows应用软件就十分方便，编程工作量相对较小，只需进行主要应用功能的编程和少量界面控制的编程。本文介绍利用VB6串行通信编程的方法对采用了RS-232接口的仪器,进行串行通信的计算机测控软件开发和实现仪器功能和指标的验收。 -With the launch of Windows 98, more and more computer users are accustomed to Windows. But Windows application software development for the general area of engineering and technology and technical personnel is not easy, but to use Microsoft Visual Basic 6.0 (VB6) to the development of these applications on Windows is very convenient, programming workload is relatively small, only major applications programming a small amount of control and interface programming. This paper describes the use of VB6 serial communication programming method used to the RS-232 devices, serial communication control computer software development and the achievement of equipment functions and targets of acceptance. 下载
