Taking into account the random charge fluctuation on embedded micro spheres in low pressure gas discharge two differential equation for two-dimensional dust lattice wave is derived. 2D hexagonal crystal is investigated in this paper. The dispersion relation for both longitudinal and transverse waves in different direction is studied as well. It is in agreement between analytical results and the experimental ones reported previously.
