摘　　要：In this paper we consider the domain decomposition methods with mortar element Lagrange multipliers to two-dimensional elliptic problems.We shall construct a kind of simple preconditioners for the corresponding interface equation.It will be shown that condition number of the preconditioned interface matrix is almost optimal.

关 键 词：Domain decomposition  non-matching grids  Lagrange multipliers  precon-ditioner  condition number.
