摘　　要：s-凹函数与几何不等式有紧密联系.利用著名的Ros不等式和基本不等式得到了拟Ros不等式,根据s-凹函数的几何性质得到了关于s-凹函数的拟Ros不等式.There exists amazing connections between s-concave functions and geometric inequality.In this paper,aquasi Ros′ inequality has been obtainedby means of the well-known Ros′ inequality,according to the geometric properties of s-concave functions,the quasi Ros′ inequality of s-concave functions have been established.
