摘要
本文利用加权余值法从微分方程及其定解条件出发导出了对流传质的变分问题,然后利用拉格朗日乘子法,吸收第一类边界条件。
The variational problem for convective mass transfer is derived from the differential equation and its initial and boundary conditions by means of the weighted residual method. Then its generalized form is established based on the Lagrange multiplier method by absorbing the first kind of boundary condition.
