| Abstract: | The Lagrangian method with proximal term （Algorithm 1） is introduced for solving the seismic inverse model. We analyze the convergence condition of the algorithm and obtain improved algorithm （Algorithm Ⅱ, Ⅲ）. Numerical result shows that Algorithm III is greatly efficient. Comparing with Algorithm I, no more than 40% iterations it needs to solve the model, and its efficiency is not strongly affected by proximal term. |

| Keywords: | seismic inverse model monotone variational inequalities Lagrangian method with proximalterm self-adaptive |
