The invention caches or absorbs the impact self-unloading truck with spreading machine, so to stabilize the exterior loadings on the machine, achieving continuous rolling improving the road smoothness.

本发明可缓冲自卸卡车与摊铺机所产生的碰撞，使摊铺机所受的外负荷保持恒定，实现连续稳定摊铺，提高摊铺路面的平整度。

By applying in seven spot, the directional control blasting technology by using slotted cartridgc has been confirmed that can increase the distance of hole in perimeter 50% on present basic, the ratio of half hole scar to 85%～95%, and the utilization ratlo of shot hole 10%.

通过在山东、山西、安徽、河南等省的七个矿区现场应用，证实了采用切缝药包定向断裂控制爆破技术，可使周边眼间距在现有基础上增加50％以上，周边眼的炸药单耗降低30～50％；循环炮眼数减少15～25％；炮眼利用率提高了10％以上；半眼痕率提高到85～95％；周边不平整度小于100mm，这一指标是目前国内外岩巷生产中最佳指标；每米岩巷掘进成本可降低200元以上，展现了定向断裂爆破技术广阔的应用前景。

Its installation means uses stickup formula, construction technology is more sophisticated, taller also to the flatness requirement of the ground.

它的安装方式采用粘贴式，施工工艺比较复杂，对地面的平整度要求也较高。

Levelling degree: Three meters of straightedge discrepancy in elevation do not exceed three millimeters.

1.3 基础技术要求。1.3.1。平整度：三米直尺高差不超过三毫米。

A type of coating applied to the substrate surface to improve adhesion of a subsequent topcoat.

一种用于涂装基材表面改进顶涂附着力的涂层，改进耐腐蚀性能，遮盖力，表面平整度。

The scanning reticle is designed to allow for a large mounting gap and liberal mounting tolerances. This system is insensitive to waviness of the steel tape due to poor mounting conditions.

扫描头上扫描模板栅线的设计使该测量系统有较大的安装间隙和安装公差，所以该系统对钢带尺条安装的平整度要求不高，从而便于安装。

AK-13A anti-slip layer not only improve stability,wearproof and permanent of pavement,extend usage life of pavement,but also improve anti-slip function of pavement,so that increase driving safety and comfort,greatly decrease the frequency of traffic accident,and bring about enormous economical and social benefit.

不仅增加了路面的稳定性、耐磨性、永久性，延长了路面的使用年限，而且提高了路面的平整度和抗滑能力，从而增加了行车安全性、舒适性，还大大减少事故的发生频率，其所带来的经济效益和社会效益难以估量。

Due to the short Fermi electron wavelength of metals, for a successful research of this problem, atomically flat films must be prepared, and their electronic structure, which is atomic-layer sensitive, must be accurately characterized.

由于金属电子的费米波长很短，要观察到显著的量子效应，必须要克服两个难点：既要制备出具有原子级平整度的薄膜，又要对其电子结构进行精确表征。

However, for the surface nitrided with the closed N2 cell shutter, after nitridation process at 500℃, the(3 × 3) RHEED pattern was observed and the surface still kept atomically flat.

但是，在关闭N2发生器挡板的情况下，在500℃下，经过氮化将观察到(3×3)再构的RHEED花样，表面仍保持原子级的平整度。

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。
