摘　　要：用ASPEN PLUS调出已知物质物性数据,通过与相似的未知物性物质的物性进行比较分析,用MATLAB拟合未知物物性间变化曲线方程。根据现有文献中的数据资料或实测数据资料,结合物性间变化曲线方程,推算出未知物的物性数据,然后应用于流程模拟及工程设计中。The physical properties of known physical properties were retrieved with ASPEN PLUS.The curves of the physical properties of the unknown physical properties were fitted by MATLAB with the physical properties of similar unknown physical properties.According to the data in the existing literature or the measured data,combined with the curve between the properties of the curve,to calculate the physical properties of unknown substances,and then applied to process simulation and engineering design.
