  1. Cross - boundary traffic has increased significantly over the years, with the growth in economic and social activities between hong kong and the mainland. lo wu is currently the only rail crossing to the mainland. it is operating at near to full capacity, handling some

    隨著本港和內地的經濟、社會連系日益密切，過境交通的數量大幅增長，羅湖是目前唯一通往內地的鐵路邊界通道，所處理的客量已接近飽和，在平日達
  2. With the construction of the west of our country developing at top speed and the need of construction of mountainous expressway, the tunnel engineering, especially the tunnels on the mountainous expressway, will be increased. if the design of support structures of the tunnel still adopts traditional design methods, it will be difficult to give full considerations for the reasonability in economy of the sections of the support structures and for the reliability of bearing capacity and stability of the support structures

    隨著我國西部建設的高速發展和山區高速公路建設的需要，隧道工程特別是山區高速公路隧道工程將會日益增多，隧道支護結構的設計若仍採用傳統的隧道支護結構設計方法將難以充分兼顧支護結構斷面經濟上的合理性和支護結構承載力與穩定性的可靠性，往往安全系數偏大，不能達到「最優設計」的目的。
  3. With the updating of wdm system and development of optical transition network, gain - clamped erbium - doped fiber amplifier ( gc - edfa ) fixes the problem of gain fluctuation and vibrating when input power and upload channel numbers are changing

    隨著wdm系統的升級及光傳送網路的發展，增益控制摻鉺光纖放大器（ gc - edfa ）在輸入功率和通道數目變化時維持放大器增益穩定方面，發揮著日益重要的作用。
  4. On the other hand the crosstalk of the wdm signal at fan - out of demultiplexer will increase with the power difference of the each channel. therefore, the gain of optical amplifier to wdm signal must have small ripple. one of the solutions is using two or more pumps with different wavelength and power according to the range of signal light to be amplified and raman gain coefficient of the fiber

    另外，各路信號光之間較大的功率差異會增加wdm通道解復用器輸出端的串話，所以光放大器對wdm各路信號光的增益要滿足一定的增益平坦度，解決該問題可以根據所要放大的wdm信號光的波長范圍和所用光纖的拉曼增益系數譜，採用多個不同波長和功率的泵浦光源進行泵浦。
