| Abstract: | The variational principle of the molecular diffusion in mass transfer is established by means of the weighted residual method from the differential equation with its initial and boundary conditions . Then its generalized variational principle is established on the basis of Lagrange multiplier method by absorbing the first kind of boundarg conditions . |
