摘要
本文利用MEYER的不变嵌入法,计算边界类似于Stefan问题的化学反应中自由边界问题,并进一步讨论它的收敛性,以及改进MEYER的不变嵌入法,使改进后的计算精度更好。
This paper deals with the calculation of the free boundary problem in chemical reaction, the MEYER'S way of invariant embedding is used for the calculation. The problem with integral calculation assimilaties the Stefan problem on the boundary. Besides its convergence is discussed. Finally, the MEYER'S way of invariant embedding is improved, and thus the accuracy of the result of calculation is much better.
