According to Hook's law (Hooke's law), in the elastic limits, the stress and objects into a linear relationship should be.

Methods and results We assume the carotid arterial wall is the elastic material so we can use the Hooke's law to analyze it. The experiment is based on the use of ultrasound B-mode imaging technique and the off-line image analysis. Elastic tube phantom experiments demonstrated the validity of the technique, providing the size of the tube within 3% of the actual values. The system was also tested in the common carotid arteries of 10 healthy males (age 23.6 y). According to the experimental result, it shows that our index is less variant than Peterson's elastic modulus. The results of and are and respectively.

根据橡皮管的体外实验结果，利用超音波以及影像分析所得到的橡皮管尺寸，与实际尺寸间的误差只有3%，而使用超音波 B-mode 量测颈动脉的实验结果显示，在把颈动脉当作完全弹性体的假设下，所得到的 CIMT 硬度指标，於十位平均年龄为23.6岁的年轻健康男性中，结果与过去文献中常使用的 Peterson's elastic modulus 相比较，结果显示容易受到不同受试者间，不同的生理状态之影响，而在考虑受试者的 IMT 变化情况下，比能够反映更多的受试者颈动脉材料性质，因此得到了较为稳定的实验结果。

The main results of the investigation are as following:(1) Some important criteria for the design of multi-layer structure are acquired: the ratio of the layer thickness to the contact diameter should be controlled to a value about 0.8; increasing the number of the gradient layers and elasticity modulus of the top layer would benefit to the yield strength and the stress status at the interface.（2）By means of molecular dynamics simulations for a indentation and sliding process, it is discovered that dislocations of 45 direction to the surface occur in the surfaces layer, which is correspond to the direction of the plastic flows observed in the macroscopic continuous medium. The irreversible deformation caused by the dislocation and the atom piles at the surface are responsible for the irreversibility of the force response. They are also the main factors for the friction generation. The temperature and the indentation velocity have significant effects on the deformation behaviors of the material of the surface layer. The yield strength would increase obviously if the indentation velocity is greater than 10 m/s.（3）A method to evaluate the fracture toughness of coating by estimating the crack-density functionβof a Wicker''s indentation was proposed. Meanwhile a new surface treatment technology was developed using non-equilibrium plasma.（4）A MD-FE hybrid method and corresponding software was developed to analysis the tribological behaviors for multiplayer system.

研究主要内容和结果有：（1）得到指导梯度膜设计的几个准则：控制膜层厚度与接触半径比在0.8左右为宜；适当增加梯度层层数和顶层弹性模量，有利于提高抗屈服能力和改善界面处的应力状态；（2）通过对嵌入和滑动摩擦过程的分子动力学模拟，发现表层产生一个与宏观连续介质的塑性流动方向观测一致的45 方向位错；位错造成的不可逆变形和表面的原子堆积，是力的响应不可逆性的原因，也是构成摩擦力的主要因素；温度和嵌入速度对材料变形特性有显著的影响，当嵌入速度大于10 m/s时，屈服强度明显增加；（3）提出压痕裂纹密度系数β半定量判定膜层断裂韧性的方法；并开发出表面强化新工艺；（4）开发出分析表面摩擦学特性的MD-FE复合模拟方法和相应模拟软件。

The work hour elasticity to wage rate of female and male is -0.3237 and -0.3167 respectively in low income group and the work hour elasticity to wage rate of female is 0.1429 in middle and high income group, so there is inverse S curve in 2002 China's urban labor market.

低收入群体女性和男性工作时间的工资弹性分别为-0.3237和-0.3167，而女性中高收入群体工作时间的工资弹性为0.1429，说明倒S型劳动供给曲线在2002年中国城镇劳动力市场是存在的。

Mr Ismail's life has changed in many ways since his involvement with JGI's TACARE.

自参加JGI的 TACARE项目以来， Ismail's先生的生活的很多方面都改变了。

Along with Annika"s uncommon take on architectural and nature-inspired pendants, cuffs, and earrings, Philippe"s mutually complementary professional experiences-including marketing studies at New York University and extensive production work and jewelry-making abroad-helped quickly grow the brand: Soon after opening their boutique, the Salames began expanding by boe with a larger retail outpost in SoHo and the establishment of a new wholesale jewelry business.

设计师- Annika本身有著北欧瑞典的斯堪地纳维亚的血统，而她的设计创意更因其历练而展现出多元化的特质，研读於瑞典的时尚设计以及纽约Parson's学院的室内设计以及日后接触顶级订制服的制作实习等经验，都让Annika能迅速地结合所有的特色而在当代的珠宝市场领域中开发出新颖诱人的作品。而与Annika灵感取源於建筑、家具与自然等的设计经验有所不同，Philippe则是在市场行销以及珠宝制造上有专业的经验，这些彼此专业上的互补，也造就日后by boe品牌迅速成长的主因。
