Summary The mean dual cross-sectional measures are introduced. They are shown to satisfy a cyclic inequality similar to that satisfied
by the cross-sectional measures (Quermassintegrale). A new representation of the dual cross-sectional measures is used to
obtain inequalities relating the mean dual cross-sectional measures and the harmonic cross-sectional measures (Harmonische
Quermassintegrale) of Hadwiger. An inequality between the volume and the harmonic cross-sectional measures of a convex body
is presented. An inequality stronger than the Urysohn inequality (the harmonic Urysohn inequality) is proven. Strengthened
versions of other inequalities previously obtained by the author are also presented.

利用提升维度的方法并结合几何图形直观分析,给出一道一元函数积分均值不等式的新证明,并将原不等式推广至形式较为对称的不等式,使得原不等式成为新不等式的特例.最后证明新不等式与函数单调递减的定义等价. 相似文献
