Optical switch is the key element of all optical network. MEMS optical switch arrays, which can achieve small insertion loss, low cross talk and large switching contrast, are going to be the key considerations in the optical cross connectors and optical add/drop multiplexers for optical networking.

光开关是全光交换的关键器件，MEMS光开关由于具有潜在插入损耗和串扰低、消光比高等诸多优点而成为光网络中光交叉连接和光分插复用器的主流器件。

This experiment takes Badaling watershed in Yanqing Beijing as an example,based on 1:10 000 the large geographical scale,adopting statistical analytical methods,the authors compared the errors of the slope,aspect,average cross section curvatures and average surface coarsens curvatures while the DEM grids varies.Besides,the authors analyzed the qualitative relation between variety of grids size and the slope,aspect,average cross section curvatures and average surface coarsens curvatures with the results of calculation.

以北京市延庆县八达岭小流域为例，不考虑DEM采样点上高程误差，采用1∶10 000大比例尺，运用统计分析方法，比较当DEM网格尺寸变化时，对坡度，坡向，剖面曲率和平面曲率计算结果的误差，分析网格尺寸的变化与坡度，坡向，剖面曲率和平面曲率计算结果之间定性定量关系。

Novel shell cross-linked micelles with pH-responsive PDEA cores and thermo-sensitive PNIPAM coronas in aqueous solution were then fabricated by cross-linking the inner PDMA shells of the PDEA-core micelles.

通过BIEE对中间DMA嵌段的季胺化反应，可以得到结构固定的pH敏感的PDEA内核和温度敏感的PNIPAM外壳的壳交联胶束。

Novel shell cross-linked micelles with pH-responsive PDEA cores and thermo-sensitive PNIPAM coronas in aqueous solution were then fabricated by cross-linking the inner PDMA shells of the PDEA-core micelles.

他经不起严密的诘问而供认了事实。

Furthermore,the adsorption of acetylene on the Ni(111)surface is investigatedby DV-Xα method,as well as its migration pathway from the aligned bridgesite,the favorite adsorption site for ethylene,to the cross-bridge site.Afterstudying several reaction pathways of C2H2 on Ni(111),we find that acetylene,as the product of dehydrogenated ethylene,will migrate from the alignedbridge site to the cross-bridge site with a very small energy barrier,0.02eV.

给出了乙炔在各个吸附位的吸附结构，并在假定乙烯在脱氢前没有迁移的基础上，对各种可能的反应途径作了模拟研究，发现乙炔在平行桥位的吸附结构不稳定，通过1.24的平移和30度的旋转的耦合，迁移到垂直桥位，迁移过程中只有0.02eV的势垒。

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。
