  • na : NA ＝〈美國〉 National Archives 國家檔案館。Na ＝【化學】 natrium （〈拉丁語〉＝sodium）。
  1. In this paper, the al3 + - doped zno thin films were prepared on na - ca - si glass substrate ( microscope slides ) by sol - gel process from 2 - methoxyethanol solution prepared by zinc acetate as premonitor, monoethanolamine as stabilizator and aluminum chloride reaction. homogenous, transparent, polycrystalline zno thin film was formed finally by diping coating conducted for film - plate on substrate, drying, pre - heat - treatment, anealing

    所用的溶膠是以乙二醇甲醚為溶劑，醋酸鋅為前驅體，乙醇胺為穩定劑反應制得，用浸漬提拉法在基體上鍍膜，經烘烤、預燒、退火，最後形成均勻、透明的多晶zno薄膜。
  2. As a political system, si shi na bo produces a great impact not only on the liao dynasty society, but also on the jin, yuan and qing dynasty

    作為一項政治制度，四時捺缽不僅對遼代社會產生了深遠的影響，而且也影響到了後世的金、元、清三朝。
  3. Si shi na bo is the central expression of the liao dynastry political system and the main carrier of the qidan nationality hunting culture, also a miniature of the liao history

    四時捺缽是遼代政治體制的集中體現和契丹族狩獵文化的重要載體，也是遼代社會歷史的一個縮影。
  4. The vasomotion was induced by noradrenaline na in vivo, then the changes of vasomotion after injecting si and ngmonomethyllarginine lnmma, a no synthase inhibitor were measured respectively on a tv monitor using a tv camera mounted on the microscope, and the influence of lnmma on effect of si was also observed

    在活體情況下運用去甲腎上腺素noradrenaline ， na血管運動誘導法誘導出血管運動，分別觀察靜脈注射g單甲基精氨酸gmonomethyllarginine ， lnmma si后血管運動的變化及應用一氧化氮合酶抑制劑lnmma對si作用的影響，攝錄結果於監視器上用暫停功能測量。
  5. Wt5hzresults lnmma injection alone can inhibit the na induced vasomotion in vasoconstriction state, while si injection alone can inhibit it in vasodilation state

    結果單獨靜脈注射lnmma可使被誘導出的血管運動抑制于收縮狀態，單獨靜脈注射si可使血管運動抑制于舒張狀態。
  6. Wt5hzresults lnmma injection alone can inhibit the na induced vasomotion in vasoconstriction state, while si injection alone can inhibit it in vasodilation state. si could abolish the effect of lnmma on vasomotion but lnmma did not influence the effect of si on vasomotion

    在lnmma的有效作用時間內應用si可使被抑制于收縮狀態的血管重新擴張，血管運動得以恢復在si的有效作用時間內應用lnmma則不能使處于舒張狀態的血管收縮。
  7. Modification effect andmechanism of sr, na in al - si alloy

    合金熔體結構的影響
  8. The results indicate that the sio2 matrix exists in form of noncrystalline state, and the silver nanoparticles distribute in the matrix homogenously. the entrance of na +, which comes from the substrates, can change the structure of si - o network of the film during the heat - treatment

    結果表明，基質sio _ 2以非晶態形式存在，銀納米粒子均勻地分佈在基質中；在熱處理過程中，基片中的na ~ +進入了復合膜中，導致基質si - o網路結構的變化。
