摘要
《化工过程模拟》一书中某些微分方程组的计算机数值解,由于迭代步长选择不当产生的错误,此类错误有时不易发现,但可使模拟失真,后果严重。本文分析了问题产生的原因,并给出了避免出现此类错误的一般原则。
Some mistakes on the numerical solution of the differential equations in 《Process Simulation》 by W.F. Ramirez are pointed out. The main mistake is that the time step selected is unsuitable and makes the dynamic simulation distort. Sometimes this kind of mist-atakes is not easy to find and often leads to Incorrect results. In this paper, the couse of the problem is analized and a general rule of avoiding such mistakes is given.
