中文拼音 [cíbàoxiāng]
磁暴相
英文
phase of magnetic storm-
Value, and the current density and intensity versus the substorm phases. moreover, the characteristics of substorm current wedge are given special attention. it is found that the density and intensity of facs reach their peak during the expansion phase, the onset of the expansion phase is triggered when imf is changed to southward from northward or the southward imf decreases, and the positions of onset are most likely to be at the edge of plasma sheet near the earth
值分佈以及場向電流強度和密度隨亞暴位相的變化，並著重分析了亞暴電流楔的特徵。結果表明，亞暴膨脹相的場向電流強度和密度都達到極大值亞暴的膨脹相是由行星際磁場轉向或南向分量變小觸發的，其起始位置很可能位於近地等離子體片內邊緣。Basic standard for the calculation and measurement of electromagnetic field strength and sar related to human exposure from radio base stations and fixed terminal stations for wireless telecommunication systems 110 mhz - 40 ghz
與人體暴露于無線通信系統110 mhz 40 ghz基地電臺和終端電臺相關的電磁場強度及sar的計算和測量基本標準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。This paper consists of four chapters. the main research is on the coronal hole, the recurrent geomagnetic strom, their relations and the prediction of the recurrent geomagnetic strom. it includes
本文對冕洞和重現型地磁暴的特性、相關關系，以及重現型地磁暴的預報等方面進行了分析和研究，全文共分四章。" geomagnetic strom " is the one of geophysical phenomena and it is important and related with the solar activities
地磁暴是一種與太陽活動相關聯的、重要的地球物理現象之一。A number of epidemiological studies have reported an association between human cancers and various surrogate measures of power frequency electromagnetic fields ( pf - emf ), but the epidemiological studies done in the past 20 years as a whole showed no persuasive evidence on the causal link of interest mainly because of methodological flaws, in particular inadequate exposure assessment and scarcity of exposure parameters, if any, truly associated with cancer
摘要累積超過二十年的時問，雖有許多流行病學研究發現，極低頻電磁場與人類癌癥發生有關，但整體流行病學研究仍未能提供充分證據說明極低頻電磁場與人類癌癥之間是否具有因果關系；其中最主要的原因是，流行病學研究所使用的電磁場暴露評估方法並不完善，並且無法確定真正與癌癥相關的暴露參數。Millimeter wave object detection makes use of the electromagnetic thermal emission of the subject and reflected thermal signals from the background, millimeter wave object detection, in comparison to visible or infrared object detection, has great potential advantage of detection through fog 、 cloud 、 smoke 、 sandstorms and other poor weather conditions
毫米波目標探測是利用目標、背景的電磁熱輻射來實現的，與可見光及紅外探測相比，毫米波目標探測在霧、雲、煙塵、沙暴等惡劣氣候條件下具有潛在的優勢。分享友人
