近几年来,相图和热力学函数的计算机绘制引起了人们的广泛注意。手工绘制复杂的二元和三元相图及热力学函数不仅工作量大而且常常会引起误差。如果要把计算相图或热力学函数和大量的实验数据相比较,手工绘制几乎是不可能的。我们在德国西门子公司的7570C计算机系统拥有的图形设备CALCOMP上编制了绘制二元和三元相图及热力学函数的通用FORTRAN程序,并用此程序绘制了大量的二元和三元相图及热力学函数,结果甚为满意。
In recent years, computer drawing of phase diagrams and thermodynamic functions has drawn people’s attention. Hand-drawn complex binary and ternary phase diagrams and thermodynamic functions are not only burdensome but often cause errors. If you want to calculate the phase diagram or thermodynamic function and a large number of experimental data compared to hand-drawn is almost impossible. We have compiled a generic FORTRAN program for drawing binary and ternary phase diagrams and thermodynamic functions on CALCOMP, a graphic device owned by the Siemens 7570C computer system in Germany, and used this program to draw a large number of binary and ternary phase diagrams and thermodynamic functions , The result is very satisfied.
