| Abstract: | In this paper, the convection - diffusion equation was transformed into the pure diffusion equation , and solved by the Laplace transform was solved with the numerical transform inversionfl The calculator resuhs of selecting dif- ferent Laplace transform parameters were compared by examples. The effect of the Laplace transform parameter on the calculation accuracy was analyzed and the selecting form of the P value was given. |
