未磁化區
英文
unmagnetized region-
The thesis points out that while large investment in agriculture has not started, small towns in yuebei mountain area should have pre - consciousness. they can not completely copy the experience of " industrialization of village " in coastal developed area. they should make full use of their specific characteristics and advantages to develop anti - magnetic nucleate towns, so as to strengthen their magnetic force and influence, therefore counter against the strong appeal of factor of production and create conditions to meet the industrial expand from the developed pearl river delta
文章概述了「反磁力型」中心鎮的思想淵源和區域基礎，指出在工業發展尚未達到反哺農業的階段，粵北山區小城鎮應當具有超前意識，利用自身優勢和特色發展「反磁力型」中心鎮，提高其吸引力和輻射作用，從而抗衡沿海發達地區對生產要素的強大吸引力，同時也為下一階段接受珠江三角洲等沿海發達地區產業擴散創造條件，而不能一味地模仿沿海發達地區「農村工業化」的路子。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。
