Abstract：
Using the strong coupling expansion method in lattice gauge theory,we calculate the weak interaction matrix elements of │ΔS│=2.Our results of the K_L-K_S mass diference are not only consistent with those of meson mass spectrum obtained by the same method,but also close to the experimental value.
