The M7350、M7363 type horizontal spindle surface Grinder with Rotary Table Particularly for girnding of work piece in ring shape,friction wa- fer,saw plate.scaled disk.

M7350、M7363型卧轴圆台平面磨床主要适用于磨削、盘型刀具、摩擦片、锯片、分度盘活塞环等圆形工件。

Author develop ELID grinding technology system, on MM7120A surface grinder and fulfilled a lots of ELID ultraprecision mirror grinding for kinds of hard and brittle materials. To use this method, the surface roughness of mechined materials can reach nanometer gade (Ra0.006～0.010 μm), and can replace parts of grind and polish technology.

本文作者开发了在MM7120A平面磨床上的ELID磨削工艺系统，实现了对多种硬脆材料的ELID精密镜面磨削试验，工件表面粗糙度可达nm级（Ra0.006-0.010μm），可取代部分硬脆材料的研磨、抛光工艺。

According the leakage test with different incident angles of the Sine and Gaussian pulse plane wave source, the numerical results show that SP-FDTD can achieve a perfect total-field/scattered-field separation, making leakage at below -340dB.

通过对不同入射角度的正弦平面波源及高斯脉冲波源的泄漏测试，结果表明SP-FDTD可以实现完美的总场/散射场分离，使得泄露降至-340dB的水平。

From 20 degrees above the ring plane, Cassini's wide angle camera shot 75 exposures in succession for this mosaic showing Saturn, its rings, and a few of its moons a day and a half after exact Saturn equinox, when the sun's disk was exactly overhead at the planet's equator.

从20度以上的环平面，卡西尼号的广角镜头，连续75个暴露这个马赛克显示土星环和其卫星一天半的一些具体土星春分后，当太阳的磁盘上，正是开销地球的赤道。

The orbit of Iapetus is also unusual, being tilted to the plane of Saturn's orbit by an unusually high fifteen degrees.

Iapetus还有其他无法解释的特征：Iapetus的发光部覆盖着无法说明的细长的经脉；Iapetus的运行轨道也很奇特，相比土星轨道平面，异常的高了15度。

The class one which was expressed by diameters of pore maximum inscribed circle was adapted and a new distribution model expressed by diameters of pore area equivalent circle modified with fiber thickness was presented.

以几何概率和平面随机分割理论为依据，分析了非织造布中孔隙结构的分布模型，将经典的以内按圆直径表示的有效孔径分布模型改为以面积等效圆直径表示的有效孔径分布模型，并结合纤维细度进行修正，实验证明，该模型更符合实际情况。

Definition 2:line,plane,interspace call 1-degree space.

定义2：线，平面，立体空间，叫做1度空间。

Recursive tree is defined by Meir and Moon as the variety of non-planarincreasing tree such that all node degrees are allowed.

递归树由Meir和Moon定义作非平面增长树的一种，且所有节点出度都是允许的。

Based on the data of four seasonal investigations in Yangtze River estuary (28°00'-32°00'N, 122°00'-123°30'E) from the year 2002 to 2003, the distribution pattern of pelagic mollusc, the seasonal changes of total abundance and the species composition were analyzed. Furthermore, environmental adaptation of dominant species was deduced through scatter plot of abundance and temperature-salinity.

根据2002-2003年长江口28°00'-2°00'N、122°00'-123°30'E海域4个季节的海洋调查资料，运用定量、定性方法，探讨了长江口邻近海域浮游软体动物总丰度的平面分布、季节变化、种类组成及优势种的环境适应类型。

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。
