路面

The frictional contact problem of tread element with rigid road surface is calculated by using numerical method.

运用数值方法对胎面橡胶单元与刚性路面相互作用时的摩擦接触问题进行了计算研究。

The numerical example shows the validipy and effectiveness in the analysis of the contact problem of tire/road interface by this approach.

轮胎 /路面的接触问题是一个强非线性问题，这决定了求解这类问题的复杂性和困难性。

In view of these disadvantages in the FEM model for the tire geometry, however, a new piecewise Ritz procedure is developed and presented in this dissertation for semi-analytical study of the contact problem of tire and road interaction.

针对现有的轮胎分析模型的计算量大并且不够精确的不足以及轮胎的几何结构和它的特点，本文发展了分片Ritz法进行轮胎／路面的接触问题分析。

Although it is very old, the car can putter along on the flat.

尽管车已很旧，它还能在平坦的路面上慢慢地跑跑。

The content of effective constituent and fineness of quicklime powder are main reasons influencing quicklime quality.

分析了生石灰稳定土基层中造成路面大面积病害的原因，阐述了生石灰粉中有效成分的含量和生石灰的加工细度是影响生石灰粉质量的关键。

The author proposes two types of instruments for measuriug the radius of curvature of the pavement .

然后提出了两个路面曲率半径仪的设计方案。

The method of white noise simulation on road roughness based on rational function is analyzed with its disadvantages pointed out.

对基于有理函数的路面不平度白噪声激励模拟方法进行了分析，指出了该方法存在的不足。

Using the Matlab/Simulink program package, a time domain model of road roughness based on rational function is found and simulated.

The interactions among large air voids, the dynamic hydraulic pressure, the non-uniformly distributed load, the overload, the environment condition and the material lead to the deficiency of the adhesion between asphalt and aggregate. The immigration of the asphalt leads to the new bleeding and inside raveling. The pumping and settlement occurred once the water penetrates the whole asphalt layer.

大空隙率、动水压力、荷载的非均布、超载以及气候条件与路面材料的相互作用造成了沥青与集料粘附性的相对不足，面层内部沥青膜剥落后向上部迁移，这是新泛油、内部松散的产生机理；更为严重的情况下，外界水直接贯穿沥青面层对基层顶面的冲刷将诱发泛浆和沉陷。

As I lie awake in bed, listening to the sound of those razor-sharp

我躺在床上睡不着，听着雨点劈里啪啦地打着路面，思绪万千

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。
