  3. We have found the best ways to optimize the growth of quality zno films and got highly c - axis oriented zno films. the microstructures of the films were observed by afm. after analyzing the crystal structures, the crystal tropism and the surface conformation flatness, we found the result that the substrate temperature of 400 ? is ideal for silicon substrates, which conforms to the result of the structure analyse. by analyzing the magnetism of zno films, we found that the films appropriately doped with fe, co ions have magnetism at room temperature and their magnetism can be improved by doping other little cu ion, but it is not certain that the content of cu is higher, the film has more magnetism, so it has the best content of cu. moreover, the films which have best crystal structures may not have the best magnetism

    我們採用原子力顯微鏡（ afm ）方法觀察薄膜的顯微結構，利用所得的圖象信息對薄膜的晶粒結構、晶粒取向、表面形態平整度等進行分析討論，認為400的襯底溫度對硅襯底薄膜是合適的，與結構分析的結果一致。通過對薄膜磁性能的分析和研究，我們得出一些有意義的結果：適量過渡金屬離子fe 、 co摻雜的zno薄膜，在室溫下具有鐵磁性，而在此基礎上摻入少量的cu離子能改善薄膜的磁性。摻cu量有個最佳值，而且結構最好的薄膜磁性不一定最好。
  4. Identification of spectra lines of ni - and co - like ions of laser - produced ta plasma

    鉭激光等離子體類鎳和類鈷離子譜線辨認
  5. In the investigations of the nanosized zirconia powders co - doped with yb3 + - 0. 2 ( 0. 4, 1 ) mol % tm3 + ions under 980nm ld excitation, the blue up - conversion emission at 474nm comes from the 1g4 - 3h6 transition

    詳細研究了鉺離子摻雜二氧化鋯納米材料的上轉換發光性質，得到：在低摻雜濃度（不大於1mol ）下，鉺離子主要發綠光。
  6. The 0. 28xl0 ~ _ ( 9 ) t carbon derived from atmospheric co _ ( 2 ) is transferred from atmosphere and biosphere to the ocean by surface rock weathering processes. in order to monitor the quality of the river, it is also important to understand the natural flux of dissolved ions

    珠江流域3條主要支流的化學風化過程存在明顯差異，西江和北江流基本以碳酸鹽類溶解為主，而東江河水扣除大氣降水的來源外，溶解質基本出自硅酸鹽類的風化。
  7. By means of the afm made in shanghai aijian co., ltd. and digital instruments co., ltd ( u. s. ), the dna strand and their fragments were observed successfully. 2. by comparison with afm experiments of three categories of ion beams, the result has been observed in qualitatively : in the uniform dose, the higher let heavy ions have caused more double strand breaks than the lower let radiation

    通過afm對實驗結果的觀測，可以定性地得知：在同等劑量條件下，高let值的重粒子與低let的射線相比， dna雙鏈斷裂的數目要多一些；在相同let條件下，隨劑量增加dsb的片段變短、數量增加。
  8. The diffraction peak angle does n ' t change obviously as co / fe ratio, it is attributed to the radius of co fe ions are fairly similar, so the influence of substitutions on unit cell is small

    而隨著co fe比的變化，衍射峰角度值變化不明顯，這是由於co 、 fe離子半徑相差不大，它們之間的位置取代對晶胞的整體影響相對較小。
