摘要 利用积分几何中估计包含测度的思想给出常曲率平面上一些新的逆Bonnesen型不等式.这些不等式在欧氏平面上为著名的Bottema不等式的改进形式与新的逆Bonnesen型不等式. We obtain new reverse Bonnesen-type inequalities for a surface of constant curvature by estimating the containment measure in integral geometry.These inequalities are generalizations and improvements of known Bottema inequality and new reverse Bonnesen-type inequalities in the Euclidean plane.
