摘要：

Dust acoustic solitary waves are investigated on the nonlinear, unmagnetized homogeneous dust ion electron plasma with variable dust charge and two temperature ions. The Sagdeev's pseudopotential is determined in terms of u(d), the dust ion speed. It is found that there exists a critical value of u(d), beyond which the solitary waves cease to exist. This critical value of u(d) depends on other plasma parameters also.
