摘    要:一阶常微分方程a(y)y'^3-xy'+b(y)=0有奇解的充分条件是2a(y)=a'(y)b(y)+2b'(y)a(y);若有奇解,则奇解为x=3·2-^2/3a1/3(y)b2/3(y)。

关 键 词:常微分方程  奇解  充分条件

Abstract:If the sufficient condition is a(y)y'^3-xy'+b(y)=0 then the differential equation 2a(y)=a'(y)b(y)+2b'(y)a(y) has a singular solution x=3·2-^2/3a1/3(y)b2/3(y)
Keywords:ordinary differential equations  singular solution  sufficient Condition
