Three different aspects of anisotropic deformation including lateral strain , relative proportional relation of lateral strain and strain in load direction , and train increment induced by unit stress increment in load direction will be delicately analyzed . the stress strain relationship in different principal stress load direction can be reflected in the anisotropy of tangent elastic ratio or strain increment in load direction induced by unit stress increment in load direction 侧向变形可以从侧向应变、侧向应变与加荷向应变之间的相对比例关系或侧膨胀系数以及加荷向单位应力增量所引起的侧向应变增量三个不同方面深入细致地分析研究；不同主应力加荷向的应力应变关系各向异性可以反映在切线弹模以及加荷向单位应力增量引起的加荷向应变增量的差异中。
Thus how to do that is raised . the so - called " structural pollution " means some structure in economic system is involved in pollution , which in fact is a sort of proportion or distribution , certain ratio of which forms some definite feature of pollution . while one converts , so does the other 所谓的结构性污染是指污染的状况与经济系统中的某种结构有关，这种结构实际上是一种比例关系或分配关系，一定的比例关系或分配关系就形成了一定的污染特征，如果结构或分配关系发生变化，那么污染的特征和状况也就发生变化了。
In character segmentation , it analyzes and compares a lot of algorithms about license plate image enhancement , binary image and standardization and geometrical revising . furthermore , it presents adaptive gray level flexing algorithm . and then , a character segmentation method is used to segment character , which is based on projection and pre - known knowledge of the size and the space between characters of characters of vehicle license plate 在字符分割方面，分析比较了牌照图像增强、二值与标准化以及几何校正的各种算法，在此基础上，提出了自适应灰度拉伸算法；最后采用投影法，并借助牌照字符宽度、间距的固定比例关系等先验知识实现了字符的分割。
The proportion relationship on corporation ' s long - term indebtedness and interests form capital structure of the corporation , capital structure relate to the decision making in investment and financing directly , to the maximum of the stock holder ' s wealth and the creditor ' s interests rate which accord with the risk they take on 企业长期负债和权益之间的比例关系形成企业的资本结构。企业的资本结构直接关系到企业的投资决策和筹资决策，关系到企业股东财富最大化是否能够实现，债权人是否可以得到与其承担的风险相对应的收益率。
Secondly , this paper set up the diffusion model of innovation incorporating price , advertising and distribution , and given the optimal diffusion equation and characterized qualitatively optimum price , advertising and distribution . furthermore , it studied the ratio relations among the advertising elasticity of demand and the price elasticity of demand and the distribution elasticity of demand . finally studied the influence of marketing mix variables to the technology diffusion 然后建立了含商品定价、广告费用和销售费用等的技术创新扩散模型，给出了扩散最优方程和商品价格、广告费用和销售费用的最优曲线，进一步地，本文分析了广告费用对需求的弹性、商品定价对需求的弹性以及销售费用对需求的弹性之间的比例关系，探讨了这些外部市场变量对创新扩散的影响。
