X-ray diffraction is one of the most common and efficient ways to measure a superlattice structure. This dissertation displays the detail results for characterization of Ge〓Si〓/Si superlattices by x-ray diffraction (including x-ray small angle diffraction and double crystal diffraction). It was found, when the growth temperature is lower, the intensities of xray small angle diffraction peaks are modulated by a periodical function, which indicates that both sets of interfaces of the superlattice is highly flat; when the growth temperature is higher, the diffraction peak intensities are simply decay with the increase of diffraction vector, which indicates that one set of interfaces is highly flat but another is not; when the growth temperature is very high, the diffraction peaks are reduced more rapidly, which indicates that both sets of interfaces are not ideal.

本文详细介绍了用X-射线衍射（包括X-射线小角衍射和双晶衍射）方法对Ge〓Si〓/Si超晶格结构特性测试的结果，尤其是发现，当Ge〓Si〓/Si超晶格的生长温度较低时，X-射线小角衍射谱峰的强度随着衍射波矢的增加而周期性调制，表明超晶格的两套界面都十分平整；当生长温度较高时，Ge〓Si〓Si超晶格的X-射线小角衍射谱峰的强度随着衍射波矢呈简单的衰减变化，对应于超晶格内有一套界面不平整的情况；当生长温度进一步提高时，X-射线小角衍射峰明显减少，表明超晶格内两套界面都不理想。

Gray stystem theroy is a new way of thinking and methods about the quality management and control by transfer theroy and probability distribution theroy controling means in the pavement smoothness construction control. Acoording to actual state, different constructors could erect homologous pavement structrue smoothness interlamination transfer models using transfer theroy, and carry out pavement smoothness construction control, it comes to obvious effect in actual application.

本文通过施工过程中的平整度传递和概率分布规律，利用灰色理论对路面平整度的质量管理和控制提出了新的方法和思路：根据工程实际情况利用传递规律的原理建立相应的路面结构平整度层间传递模型，并据此对路面平整度的施工进行控制，对施工平整度的控制起到指导作用。

According to the actual measurement result of Xi-Bao highway pavement evenness ,an unevenness model of pavement is built.

根据西宝高速公路路面平整度的实测结果，建立路面的不平整模型，并以正弦曲线模拟路面表面，建立四自由度车辆振动模型，从而为分析路面平整度的发展变化规律和评价沥青路面的使用性能提供了一定的理论基础。

Screed coat: To guarantee qualiTY and reduce waste of materials ,levelingtreatrnent should be made to the unlevel walls by use of 1:3 cement mortar,flatnesswill be 4 mm for 2m.Next step cannot be done until flatness of walls is inspected OK

找平层：为保证质量，减少材料浪费，要求对不平整的墙面做好找平处理，用1：3水泥砂浆，平整为2m靠尺4mm，并应在墙面平整度检验合格后方可进行下一步工序。

In any case, this requires version decoronated placed a significant portion of skinpass at the time, but because the imaging procedure takes direct contact exposure modes, the whole process can accept different types of plate surface changes of different planeness, and these changes are on the surface of the bltumlnous by the production of traditional plates on the surface treatment of aluminum.

无论怎样，这需要版材在平放时相当的平整，但由于成像过程采用直接接触曝光方式，整个过程可以接受各种类型版材表面不同平整度的变化，而这些表面的平整度变化是由生产传统版材时对铝基表面处理而造成的。

The existing stone cutting tool, the tool bit is constituted by the sole grade's grinding material, when cutting the rough stone, the cutting speed is quick, the cutting efficiency is high, but the cutting surface fluctuates in a big way, becomes rough, after the cutting, grind and polishing take long time to do, if use the fine grinding compound, the cutting face is smooth, but the cutting speed is slow, the cutting efficiency is low, therefore the existing stone material cutting tool cannot have the high efficiency to cut the stone which have the smooth cutting surface, in view of this, how to keep the high working efficiency and get smooth cutting surface?

现有石材切具刀头由单一粒级的磨料构成，使用粗料时，切割速度快，切割效率高，但切割面起伏大，变得粗糙，切割后研磨抛光耗费时间长，使用细磨料，切割面较平整，但切割速度慢，切割效率低，因此现有石材切具不能高效率地切割出平整的石材，针对这一现状，如何既能高效率切割，又能使切割面保持平整呢？

Aimed at the waves of thin gauge products and the limitation of leveling strip head or tail in temper mill,the function of leveling strip head has been developed and applied in production in Zhujiang Steel.

Moreover, a belt planishing mill setting is one of the major sectors of the belt cold rolling sets, in which a steel roll annealed is received in the device from the last course, and after planished a steel belt with certain extensibility and surface roughness is gained. The steel belt, after having planished, has eliminated its yielding platform, and it can improve its quality outstandingly to meet with the increasing demands in the market.

而板带平整机组是板带冷轧机组中重要的一环，该区域设备承接经退火之后的钢卷，经平整后，得到有一定延伸率和表面粗糙度的钢带，平整后的钢带消除了屈服平台，可显著提高板带的质量，从而满足市场日益增长的要求。

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。
