    今晚約十時，警方接獲地鐵公司報告指一名車長發現在天後地鐵站的隧道天花有人匿藏，警方遂派員調查，到場的警員發現有一名男子匿藏於隧道內通風槽與天花之間的位置，於是勸喻他返回地面，警方最終于約晚上十時二十五分將該名二十五歲男子制服，男子其後昏倒，被送往鄧肇堅醫院接受治療，事件發生期間，介乎北角至天後地鐵站的地鐵服務曾一度暫停，警方現正調查該名男子是否與今日凌晨在北角和富中心發生的搶劫案有關。
  4. Secondly, ground on the duct noise control, the delayed - lms algorithm, which is actulized easily, is brought forward, then the simulation on pc is achieved. it is shown from the computer simulation that for the single frequency noise, there will be a good effect when choosing the suitable parameters ; but for the narrowband noise, the effect will become worse with increasement of the bandwidth. this result is helpful to analyze the parameters influencing anc

    結果表明： （ 1 ）隨著濾波器長度的增大，系統收斂速度變快； （ 2 ）隨著值的增大，系統的收斂速度增大，但是當值超過某一范圍時會引起系統的發散； （ 3 ）次級通路的延遲數與初級噪聲頻率有關； （ 4 ）對于窄帶信號， dlms演算法可以取得一定的降噪量，但是隨著窄帶信號帶寬的增大，降噪效果明顯變差。
