过渡位置

Under financial support by the Guanzhong Irrigation Improvement Project loaned by WB,the choice for the shapes of the water measuring flumes in U-shape canals have been carried out,based on the choice research,the straight wall type water measuring flume in U-shape canal was proposed for the optimal shape.

对U形渠道量水槽进行了选型，在选型的基础上，提出以U形渠道直壁式量水槽作为本研究的优选体型，并对U形渠道直壁式量水槽的体型、喉道长度、喉道宽度、过渡段长度、水尺位置、设计方法进行了优化研究，所得结果已在工程实践中应用，取得了良好的经济效益和社会效益。

The surface on the steel bridge is easy to damage early than estimate years.The distress types in steel bridge surfacings include permanent deformation,cracking,formation of mounds and disintegration.The text analyses the vertical section strain under tire location by use of the finite element method and calculates the influence of stiffness variance of translate bonding layer on the surfacings of steel bridges.

中文摘要：钢桥面沥青铺装层在使用一段时间后容易出现开裂、脱层以及车辙等早期破坏现象，采用空间有限元分析方法对车轮荷载位置处的截面竖向应变进行分析，计算了过渡粘结层刚度变化时对钢桥面铺装层受力变化的影响，计算结果说明对传统的弹性层状计算理论的假定与实际受力情况存在较大差异。

In our study, multiple temperature-independent points and accompanying oscillations are observed in the longitudinal resistivity between the low-field insulator and the quantum Hall liquid. The amplitudes of these oscillations can be well described by conventional Shubnikov-de Haas theory, and our experimental results therefore support the existence of an intermediate metallic regime between the low-field insulator and quantum Hall liquid.

在此研究中，我们发现在低场的绝缘态与高场的量子霍耳态之间，纵向电阻率有多个不随温度变化的交点，而此交点所在的位置与其所伴随振荡的振幅可以利用Shubnikov-de Haas 理论解释，因此由我们的实验结果可以看出，在低场绝缘态与高场量子霍耳液体态之间，的确存在一个过渡的金属态。

When the rolling stock from the Road for A shares, B shares, mechanical manipulation Switch to track mobile location Tsim Sha Tsui, a sharp rail tracks of a basic paste, pointed out the basic two-track rail 2, and this opened the B-share Road, Road closure of the A-shares, locomotives and rolling stock into the link of the rail along the curve of the transition to lead Frog and their rail unit.

当机车车辆要从A股道转入B股道时，操纵转辙机械使尖轨移动位置，尖轨1密贴基本轨1，尖轨2脱离基本轨2，这样就开通了B股道，关闭了A股道，机车车辆进入连接部分沿着导曲线轨过渡到辙叉和护轨单元。

This paper begins with case of American tire special protection as many people being focus now, comparing with development course of tire industry between international and domestic, and using industry concentration theory, industry development lifecycle theory, and value chain theory points out china's tire industry is transforming from size distribution from convergence distribution, and still in manufacturing low-end position in value chain aspects from current industry situation, deep theory analysis between both macroscopic and microscopic perspective.

中文摘要：本文从备受业内关注的美国&轮胎特保案&入题，对比国内外轮胎行业的发展历程，运用产业集中度理论、产业发展周期理论和价值链理论，从宏观和微观视角就行业国内外问题现状进行深度理论分析，指出我国轮胎行业处于由规模化阶段向集聚阶段过渡的发展时期，在价值链上仍处于以制造环节为主的中低端位置。
