Abstract: Using differential inequality,the Sturm comparison theorem of  a class of third order nonlinear differential equations is discussed,and the zero point existence of the equations is obtained.

Key words: nonlinear differential equations, Sturm comparison theorem, zero point, sufficient conditions
