As for the construction of concrete pavement of highway, our corporation is bold in innovations, overcoming the common fault in the construction process. The coincidence rate of the evenness of the concrete pavement is 100%, and the mean square value is 0.90mm, which reach advanced domestic standards.

在公路水泥混凝土路面施工方面，大胆创新，克服了施工中的通病，混凝土路面平整度合格率100%，均方差平均为 0.90mm，达到国内先进水平。

To analyze the response of pavement structure under moving loading, a quarter vehicle model with single freedom degree and unevenness model are established. The dynamic loads are calculated through combining different pavement conditions and speed. When the incentive frequency which is passed to vehicles by the road is close to its own vibration frequency, vehicles will produce the greatest dynamic load.

为了分析路面结构在行车动荷载作用下的力学响应，建立了单自由度1/4车辆模型和以正弦曲线模拟路面不平整度的模型，通过将不同路面状况和行车速度的组合，分析车辆在各情形下所产生的动荷载，发现路面传给车辆的激励振动频率接近车辆自身振动频率时，车辆对路面产生的动荷载值最大。

It is this boundary-work that makes the typology useful for avoiding extreme technological determinism, social constructivism, and noetic flatness in conceptualizing an artifact's political qualities, and for thinking about how these qualities change through time.

正是这种边界的工作，使避免极端的技术决定论，社会建构主义的类型学有用的，在构思和智力平整度的工件的政治素质，并思考如何通过时间的变化这些素质。

With the development of highway, pavement roughness has been more and more concerned.

随着公路交通的不断发展，路面平整度受到越来越广泛的关注。

Tungsten CMP is an important process to gain the global planarity of silicon wafers with tungsten plugs.

钨的化学机械抛光是用钨坯获得硅片球面平整度的重要工艺。

In addition to measure the refractive index profile of a GRIN lens, we also measure the refractive profile and radius curvature of a Plano-convex lens by means of this imaging ellipsometric technique.

本文将此简式影像式椭圆偏光术应用在非均匀平面材料光学参数之量测，及平凸透镜之量测；我们不但量出了渐变式光纤折射率的径向分布并证明其表面的平整度，另外也量出平凸透镜的曲率半径及折射率。此法可将椭圆偏光术延伸到曲面薄膜量测。

They have superior strength at low gauges, flatness, clarity and excellent printability.

他们在低超高强度计，平整度，清晰度和良好的印刷适性。

Our products aslo have characteristics of high-intensity, low-water absorption, good-smoothness, pro-environment and vivid effect.

同时还具有强度高，吸水率低，平整度好，耐磨环保，效果明快的特点。

In this paper,an objective evaluation system based on improving fuzzy clustering is proposed for seam pucker evaluation.

提出了一种基于改进型模糊聚类的缝纫平整度客观评价系统。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
