压缩因子Z计算软件的开发

本文针对本科化工热力学教学中涉及的热力学性质——压缩因子Z计算经验总结式多、计算繁琐的特点，采用Visual Basic 6．0作为软件开发工具，对物质热力学性质——压缩因子Z计算经验式进行设计。操作界面具有良好人机交互性，用户通过简单命令按钮等操作就可以得到所需结果。

This paper aimed at the characteristic of the chemical engineering in undergraduate teaching course, such as a lot of experimental data, a lot of complex expressions, complicated and trivial calculation by hand. Visual Basic 6.0 is chosen as the instrument for developing the system, and initially designed programs for calculations of properties of chemical engineering fitting the characteristic, such as compressibility factor Z, make the interface have good man--machine interaction, formatting and showing easy to control, can operate through the simple button of order on the interface.
