化工设计过程中需要查阅大量的数据图表,并进行相应的估算,过程繁琐且计算精度不高。本工作以热力学数据的普遍化关联为对象,编制程序实现了二维表格的自动检索和内插,输入温度和压力等参数即可计算出相关物质的压缩因子、剩余焓、剩余熵以及逸度系数等热力学性质。这种表格的二维检索和内插技术,对于其它表格的高效使用以及数据手册的电子化利用具有积极意义。
Chemical design process need to consult a large number of data charts, and make the appropriate estimates, the process cumbersome and calculation accuracy is not high. This work takes the generalization of the thermodynamic data as the object, and compiles the program to automatically retrieve and interpolate the two-dimensional tables. Enter the parameters of temperature and pressure to calculate the compressibility, residual enthalpy, residual entropy and fugacity Coefficient and other thermodynamic properties. This form of two-dimensional search and interpolation techniques for the efficient use of other forms and electronic data sheet has positive significance.
