Description: 使用本软件，可计算出中小型工程三相短路电流。
若已确认但尚未进行下步计算之前，发现输入的支路类型或数据有误，可单击窗体另行输入。
计算三相短路电流时，请确认短路点编号及对应的网络平均电压。
双击窗体，可以打印出窗体上的图象。但，应将打印机预设为A4纸型，横向打印。
文件打印至硬盘，可用Word软件处理后存档及打印。
本软件不采用通常的网络变换。而先建立电导增广矩阵，解此矩阵即可求出各节点电位以及各支路电压降、电流。之后，方按不同电源类型，分别采用恒定电压或机组运转曲线法，求出各支路流过的短路电流。
发现本软件有何项功能需补充，或存在错误，请与编制者及时联系。
本软件仅为试用期，务请自行仔细检查计算出的数据。
请及时更新软件。-use of the software, small and medium-sized projects translate into three-phase short-circuit current.

Description: 计算机并口用于连接打印机时，其功能极其简单，仅起传递打印命令和数据到打
印机，并返回打印机状态到系统的作用。其3个端口（数据口、状态口、控制口）在标
准模式下都是单向操作。如何设计并口扩展电路进行高速双向数据通信，又保持微机
对打印机功能的透明性，是通信电路设计人员感兴趣的一个课题。关于计算机并口用
作通信口的介绍，国内外资料不多，本文就此技术运用于数据采集系统，做个简单介
绍。-The computer parallel port for connecting to the printer, its function is extremely simple, since only a passing print commands and data to the printer, and return the printer status to the system role. Its three ports (data port, status port, control port) in the standard mode is one-way operation. How to design a high-speed parallel port expansion circuit two-way data communications, computer printer functions while maintaining transparency, the communication circuit design as a topic of interest. On the computer parallel port as communication port introduction, not much information at home and abroad, this paper on this technology into data acquisition system, to be a brief introduction.
