Some Inequalities for L_p-Dual Mixed Quermassintegrals

Wang and Zhang defined a type of Lp-dual mixed quermassintegrals based on the Lp-radial combinations and dual quermassintegrals of star bodies. In the article, the product inequalities for this Lp-dual mixed quermassintegrals are established. As the applications, we obtain the lower bounds of dual quermassintegrals product. Further, the Brunn-Minkowski type inequality and the cycle inequality for the Lp-dual mixed quermassintegrals are given.

On the Dual p-Measures of Asymmetry for Star Bodies

Recently, the connection between p-measures of asymmetry and the L_p-mixed volumes for convex bodies was found soon after the p-measure of asymmetry was proposed, and the Orlicz-measures of asymmetry was proposed inspired by such a kind of connection. In this paper, by a similar way the dual p-measures of asymmetry for star bodies(naturally for convex bodies) is introduced first. Then the connection between dual p-measures of asymmetry and Lp-dual mixed volumes is established. Finally, the best lower and upper bounds of dual p-measures and the corresponding extremal bodies are discussed.

A Quasi-Funk's Section Theorem in n-Complex Space

The Funk's section theorem in the n-complex space Cn is investigated. It turns out that this theorem does not admit an extension for the class of general origin-symmetric star bodies in Cn but for a class of star bodies called generalized complex intersection bodies. A quasi-version of Funk's section theorem in Cn is established then.     

局部受载工况下的轮胎受力分析

轮胎属于汽车唯一与地面接触的部件。轮胎性能的好坏,对汽车行驶的安全性有着极大影响。以175/70/R14轮胎为研究基础,通过有限元分析软件分析了轮胎在6种不同局部受载工况下的变形、应力、应变情况。分析表明,与正常静载工况相比,轮胎应力、应变和整体变形情况较复杂,且呈不对称性。与异物接触的胎体区域变形较大,胎侧部位和三角胶部位变形较小;应变较大区域主要集中在异物突起部,其它部位应变较为稳定。此分析结果为纠正非正常泊车,降低轮胎受损情况,消除汽车安全隐患有实用性参考价值。     

基于渠道不对称的多品牌代理零售商的应对策略研究

从零售商角度出发,针对1个零售商及2个处于竞争的知名品牌、一般品牌制造商组成的供应链系统,运用Stackelberg博弈模型,研究了当渠道势力不对称时,渠道势力居中的零售商的应对策略问题。指出在一定条件下,以利润最大化为目标的零售商采取对高质低价的一般品牌进行广告促销策略,不仅可以增加零售商销售利润,而且更为重要的是,广告促销策略还可以增强零售商的渠道议价能力,成为迫使知名品牌制造商妥协退让,进而降低产品批发价的策略性武器。     

新革命历史小说的身体凸显及暴力美学

作为新时代主流意识形态的表达,新革命历史小说与1950—1970年的革命历史小说有很大差异。一个显著标志,就是革命者的身体得到凸显。新革命历史小说对男性革命者充满杀戮快感的身躯的处理方式,体现了现代性内涵与意识形态的意义。革命者身体的凸显及暴力描写,不可避免地消解了国家意识形态的深度和力量。这类小说在身体描写上不能走得太远,应比一般的“纯文学”及大众文化谨慎、持重。

Generalized Intersection Bodies with Parameter

AIn 2005, the classical intersection bodies and L_p intersection bodies were extended. Afterwards, the concept of general L_p intersection bodies and the generalized intersection bodies was introduced. In this paper, we define the generalized bodies with parameter. Besides, we establish the extremal values for volume, Brunn-Minkowski type inequality for radial combination and L_p harmonic Blaschke combination of this notion.
