臺灣博碩士論文加值系統

許多科學家利用各種不同之儀器，觀測電離層赤道異常區的不規則體。然解有利用兩種以上的儀器做觀測與比對。本論文是用電離層探測儀和全球定位系統地面接收站研究在台灣地區（位於赤道異常區）太陽活動極大期與極小期的散狀F層和相位擾亂。除了介紹探測儀器－電離層探測儀和全球定位系統與散狀F層和相位擾亂的計算方式之外，將分別依照不同年份比對散狀F層和相位擾亂的資料，以及更進一步交叉比對兩者之間的關係。研究結果顯示在太陽活動極小期與極大期期間，不同特徵的散狀F層，其月變化分佈不同。另外，全球定位系統相位擾亂的程度在不同太陽活動性的月變化分佈也不同。而依電離層散狀F層和全球定位系統相位擾亂的比較結果顯示，頻率散狀F層與相位擾亂的關連較虛高散狀F層低。

There are many scientists have use many instruments to research the equatorial anomaly crest zone and analyze these data where they get. Because of the differentiation of instruments, the data get from them also have many differentiation. Therefore, using two kind of instruments to observe can provide detailed and overall views of this zone. It will introduce the calculation of phase fluctuation in this paper and compare different years' result.
