METHODS: A dose-response relationship of 8-OH-DPAT, spontaneousphrenic nerve activity and a nociceptive C-fiber reflexwere established simultaneously in an in situ perfused, nonanesthetized,rat brainstem-spinal cord preparation. Fentanyl was administered in situ to investigate the interaction with 8-OH-DPAT on phrenicnerve activity and nociceptive CFR.

The immunohistochemistry showed that accompanied with SDNSF mRNA upregulation, the nestin-positive cells showed erupted roots, migrated peripherad and proliferation on the 8-day slice.

结果 RT-PCR检测SDNSF mRNA在正常大鼠脊髓中的表达，损伤后4天SDNSF 的mRNA表达上升，损伤8天到达高峰，此后SDNSF 的mRNA表达逐渐减少，到16天恢复到正常水平；脊髓切片原位杂交结果发现SDNSF的 mRNA 阳性细胞主要分布于脊髓灰质细胞中，可能是神经元细胞，结果表明正常脊髓可表达SDNSF；脊髓损伤后8天，原位杂交显示SDNSF阳性细胞明显增多。

A terephthalate anion-pillared Ni-Al hydrotalcite-like layered double hydroxide was synthesized on the surface and within the pores of γ-Al 2O 3 by in situ crystallization and a polytungstate anion-pillared hydrotalcite was subsequently obtained by ion-exchange.

采用原位沉积法在γ-Al2O3表面原位合成了对苯二甲酸阴离子柱撑的镍铝水滑石，并用同多钨酸根阴离子部分交换了镍铝水滑石中的对苯二甲酸阴离子。

The research of polymer/layered silicate nanocomposite was introduced detailedly, including the classify, property and the latest research advance. On the basis of consulting the document and the exploratory experiment, the experimental method which first creative preparing poly (acrylonitrile-vinyl acetate)/raontmorillonite nanocomposite by emulsion intercalation copolymerization was established; the structure and property of polyacrylonitrle different molecule weight with inorganic mineral super fine nanocomposite was reseached. The reaction principle of PMMA by photo-initution was explored. The mixture principle with productor condition, property of PE/Clay nanocomposite milt insert was seal prived. By PS/Clay nanocomposite munufacture, the monomer ins-polymerization and polymerial solution was proved.

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.
