%X A uniformly valid approximate solution of a kind of nonlinear wave equations is studied, the research results indicate that the solution of this kind of equatiors can be represented by Airy function approximately. The usually used W. K. B. approximation is the first order approximation of the present result in the region far away from the turning point of refractivity. At the turning point of refrac-tivity, the present result is still valid.
