摘要：

Two basically different methods, formerly used sequentially to solve multicomponent thermal separation problems, are now allowed to function simultaneously within a single algorithm to ensure a rapid yet stable convergence to the solution. By combining the stability of the Rose-Sweeney-Ball method with the rapidity of the Newton-Raphson method, the solution is easily reached without encountering the difficulties of employing these methods separately. © 1979.
