  1. The preparation of gold electrode of double layers and the spectroscopic and electrochemical studies when it was incubated with bacteria : cv measurement demonstrated that the defect content within the double layer gradually decreased during the incubation, sers showed that the film structure became order during the incubation and the bands of double and triple bonds shifted toward high wavenumber, too

    循環伏安測試表明在雙分子層與細菌培養的過程中,雙分子中層中的的缺陷數量逐漸減少。表面增強拉曼光譜證實在雙分子層與細菌培養的過程中,雙分子中層的膜結構變得更加有序,且其雙鍵與三鍵的共振峰也同時向高波數的方向移動。
  2. A reliability experiment of thermal aging was carried out for the two types of joints, scanning electron microscopy, energy dispersive x - ray spectrometer and micro x - ray diffractomer were adopted to investigate the interfacial evolution behavior of joints, and kinetics model of imc formation was established. the results show that imc growth follows the parabolic law as a function of aging time at certain aging temperature, imc growth is more sensitive to the aging temperature than the aging time, the activation energy of cu - al imc growth is 97. 1kj / mol and the major forming cu - al imc are cual2 and cu9al4, the activation energy of au - al imc growth is 40. 1kj / mol and the main au - al imc are au4al and au5al2, with au2al and aual at the interfacial periphery of joints, the rate of cu - al imc growth is about 1000 times slower than that of au - al imc, and kirkendall voids and cracks are easily appeared during thermal aging in gold ball bonds while voids and cracks are absent in copper ball bonds even after aging at 200 for 2900 hours and 250 for 169 hours

    研究結果表明:金屬間化合物厚度與老化時間的關系符合拋物線法則,金屬間化合物的生長對老化溫度比老化時間更加敏感; cu - al金屬間化合物生長的激活能為97 . 1kj / mol ,老化后金屬間化合物呈層狀分佈,主要相為cual2和cu9al4 ; au - al金屬間化合物生長的激活能為40 . 1kj / mol ,主要相為au4al和au5al2 ,同時在界面周邊區域生成了au2al和aual ;老化過程中cu - al金屬間化合物生長速率比au - al金屬間化合物生長速率小103數量級;金絲球鍵合點200老化96小時出現了明顯的kirkendall空洞和裂紋,但銅絲球鍵合點200老化2900小時和250老化169小時都沒有形成空洞和裂紋。

  7. Several measures of inflationary jitters wobbled : the price of gold futures hit a 27 - year high of $ 735. 50 an ounce and yields on 30 - year treasury bonds rose

    各種擔憂通脹的數據一個個浮現:黃金期貨價格達到每盎司735 . 3美金,這是27年來的高點, 30年聯邦債券回報也在上升。
