板橋地區空氣污染預測模式之探討 / Researching Forcast Model of Air Pollution at Pacho藺超華, Lian,Chau Hwa Unknown Date (has links)
由於近年來汽機車的成長率大增，□=>許多重大營建工程陸續開工，導致
空氣污染日益嚴重，所以研究板橋地區一氧化氮濃度的預測模式。在本篇
論文中，我們首先應用集群分析將一氧化氮依濃度區分成數個集群，而後
運用區別分析診斷集群分析的結果是否合宜，最後找出集群內觀察值數目
最多的那個集群，然後將多變量時間序列中經過差分一次後的自我相關模
式應用在上面。目的是要尋求更精確的污染濃度預測值，以提供環保單位
一些訊息以作參考。
