  1. Computational fluid dynamics ( cfd ) techniques are used to study and understand fluid behavior in tunnels. by simulating complex specific operational cases, we can educe velocity or flux distribution in tunnel under different ventilation and resistance situation and determine the favorable operational procedures of the erlang mountain tunnel ventilation in a fire case. comparison has been made between a simulation and experiment for some cases in order to prove the cfd model is powerful, so that enables the study of cases for which experimental data is not available

    採用本文將隧道內的氣流看成是理想流體的一維恆定流動,通過對二郎山特長公路隧道半橫向通風系統建立隧道內的空氣動力學模型,利用計算機進行數值分析與計算,得出發生火災時,不同通風阻力條件下隧道中的風速分佈及流量分佈,並通過實驗室隧道模型實驗進行驗證與修正,依據研究結果給出了二郎山半橫向通風隧道的火災控制方案,從而解決了二郎山公路隧道通風對火災的控制問題,同時為半橫向通風公路隧道的火災通風提供科學的方法。
  2. " with the new digital - atis ( d - atis ) and digital - volmet ( d - volmet ) services, the dissemination of airfield and meteorological information, which are used to be available via radio broadcast only, can now be printed out inside the cockpit to reduce pilot s workload of manually copying the voice broadcast information. other major operational benefits of the new services include guaranteed data accuracy, no time constraint for pilots to get the information and no coverage limitation, " mr albert lam, director - general of civil aviation said when officiating at a ceremony which marked the commencement of the new services

    民航處處長林光宇主持新服務啟用儀式時說:有了新數據化服務后,飛行員除了能透過無線電廣播獲得香港自動航站情報和遠航氣象情報訊息之外,現時更可通過駕駛艙內數據通訊系統的印表機列印出來,令飛行員可免抄下語音廣播資料,從而減輕其工作量。
