  1. The recent divergence in the spot exchange rates of the hong kong dollar and the renminbi and the calm reaction in the hong kong dollar exchange rate when the renminbi had breached psychological levels, suggested that the efforts to manage market expectation and decouple the psychological relationship between the exchange rates of the two currencies had been quite successful

    近期港元與人民幣的現貨匯率走勢各異，以及港元匯率在人民幣升穿心理關口時反應平靜，顯示金管局在管理市場預期及消除人民幣升值對港元造成的心理影響方面所作的努力頗為成功。
  2. In this review, we summarized the studies of the molecular mechanisms of gene duplication, the preservation of duplicated gene, the selections acting on duplicated gene, the alternative ways of divergence and the evolution rate

    文章綜述了重復基因的產生機制、保留機制、選擇作用、分化途徑以及重復基因進化速率等方面的相關研究，揭示了基因重復對生物進化的重要性，以引起大家對該領域的關注。
  3. This method is better than the traditional method that relates the divergence of sediment transport rate to the deposition rate. the output of the tidal modelling reaches the required precision according to a comparison between the calculated tidal amplitudes / phases and the observed ones at 42 coastal tide gauge stations

    潮汐潮流的模擬計算結果與沿岸42個潮汐測站的實測值結果對比達到了精度的要求，同時，計算得到的各分潮同潮圖與實測結果相符。
  4. Based on the rate - equation theory of four - level system, the expressions of threshold pump power, output power and slope efficiency are given. the influence of space distribution of pump light ( the position of focusing point, dimension of pumping light and divergence angle ) to the output characteristics are also discussed. then, by investigating the effects of thermal effect of laser crystal on the size of laser cavity mode, we obtain the mode - matching principle of high power laser diode end - pumped solid - state lasers

    其中，在泵浦光的空間分佈變量中我們分別考慮了泵浦光聚焦后的腰斑大小、聚焦腰斑在增益介質中的位置以及泵浦光在介質中發散角的影響；然後我們研究了在高泵浦功率下激光晶體因吸收泵浦光而產生的熱效應所導致的熱透鏡效應以及熱致衍射損耗，通過分析它們對振蕩激光腔模尺寸的影響，得到了高功率半導體激光二極體端面泵浦固體激光器模式匹配的要求，為高功率連續單頻nd ： yvo _ 4激光器的優化設計提供了理論依據。
