The prepared powders were characterized by XRD, UV-Vis, FTIR, N_2 adsorption, Fluorescence spectroscopy, etc. N-doped TiO_2 evidently shows its absorbance shoulder shift into visible light region. Moreover, N-doping retards the transition of TiO_2 from anatase to rutile type as well as restrains the growth of the crystal size which leads to less decrease of surface area. These characteristics are considered to benefit the photoactivity of TiO_2; When all the samples were applied to the photodecomposition of Methylene Blue under visible light(λ＞400 nm), the N-doped TiO_2 show an obvious superiority when compared to the undoped TiO_2, the active hydroxyl groups are found to play a important role in this high photoactivity; When the same experiment was performed under UV light, all the samples show the consistent sequence of photoactivity as in the visible light.

通过UV-Vis、XRD、BET、IR、FL等表征手段测试表明：掺氮不仅使TiO_2的光吸收区域拓展到可见光区，而且有利于延缓TiO_2晶相的转换，从而抑止了高温煅烧下所引起的晶粒增大以及比表面积的降低，且氮源浓度越高，此现象越明显，这些特征都有利于催化剂光催化活性的提高；在主波长大于400nm的可见光催化亚甲基蓝实验当中，掺氮TiO_2的光催化活性明显优越于未掺氮样品，亚甲基蓝在90min内达到88％的脱色率。

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。
