ionospheric drift 中文意思是什麼
-
In this thesis, three ionospheric scintillation monitors ( ism ) are installed in haikou, hainan province of the p. r. of china, which locations are separated about one hundred meters apart, the drift velocity of ionospheric irregularitie can be deduced by analyze the cross - correlation of scintillation signals at three monitors to determine the drift time between monitors
本文通過實驗的方法，在地面上相距百米左右的距離設置三臺電離層閃爍監測儀（ ism ） ，通過分析三站衛星閃爍信號之間的相關性，分別得出不規則體在三站連線方向上的速度，然後再求出電離層不規則體的漂移速度。 -
Several influence factors to result plasma drift in hainan were analyzed. in this paper the characteristics of ionospheric parameters variation were analyzed systematically and some new results in storm - time such as seasonal behaviors were obtained ; it is the first time to investigate the ionospheric drift behavior in hainan and some new results was obtained, the relationships between each two plasma drift velocity components in storm time in hainan were found and the electric filed variation in hainan ionosphere also was obtained ; the results also show that there are big differences of the ionosphere parameters bo and bl obtained from the data with that obtained from the iri - 2001 applied for hainan ; a new phenomena was found during a strong magnetic storm, that a layer with very strong electron density and density grad was found during the recovery phase of the storm, its horizontal scale is beyond 100km and temporal scale is about 2 hours, this phenomena repeated 3 times continuously. a type of negative disturbance in high and low latitude but positive disturbance in east - asia also has been found
本文較為系統地給出了海南地區電離層的參數變化特徵，特別是得到了一些暴時與以往不同的季節特性；第一次給出了海南地區的電離層等離子體漂移特徵，發現等離子體漂移暴時擾動在三個方向上有內在的聯系，得到了電場變化曲線；研究結果還表明海南電離層的半厚指數和形狀參數等與國際參考電離層iri - 2001存在很大差別；通過對強磁擾動事件期間的參數變化特性分析發現，在磁暴恢復相期間海南地區電離層底部存在一個電子密度非常大的高密度區，高密度區底部電子密度梯度隨高度急劇增加，該區域的水平尺度可達100公里以上時間尺度約為2小時，連續出現過三次，這是一個在海南從來未發現的新現象；研究還發現了暴時東亞地區電離層擾動會出現高低緯負相而中緯正相的現象。 -
The measured result is consistent with that of dps - 4, which is obviously that ionospheric transmeridional drift is east in nighttime, and ionospheric meridional drift is south
結果與用dps - 4數字化測高儀得出的結論具有一致性，即海南地區電離層緯向（東西方向）漂移在夜間有顯著的東向，經向（南北方向）通常向南。 -
Especially, the ionospheric electric field in hainan was studied according to the ionospheric plasma drift velocity by removing the neutral wind effect
特別是採用扣除中性風的方法，研究了海南地區電場的變化特性，並對海南地區的漂移變化因素進行了分析。 -
Characteristics of variation and disturbances in low - latitude ionosphere were investigated based on the data observed in hainan under different magnetic activities and solar activities including variations and disturbances of parameters in different ionospheric layers, behaviors of plasma drift and a comparison with other low - latitude ionospheric station. the disturbance propagations from high to low latitude region during magnetic storm time are also investigated with analyzing the data obtained from the east - asian high - middle latitude stations
本文在觀測數據分析的基礎上研究了不同地磁活動和太陽活動條件下低緯電離層的變化和擾動特性，包括海南電離層各分層的參數變化和擾動特性，電離層漂移的變化特性，並與低緯度地區其他臺站進行了對比分析，還對暴時東亞地區高中緯度地區臺站的觀測資料進行了分析，研究了電離層擾動從高緯到低緯的響應過程。
