中文拼音 [cícéngdàxiǎo]
磁層大小
英文

方法對已知不同突出時間的腰椎間盤突出患者進行詢問病史、體格檢查和磁共振掃描，記錄患者臨床表現、突出時間、突出髓核及同層間盤的信號強度、突出髓核大小、突出間盤厚度、有無神經根受壓、有無黃韌帶肥厚、突出間盤變性程度、突出類型等指標。To identification when lumber intervertebral discs protrusion happen and how it happen is more and more important and urgentent. we will study clinical situation and mri of lumber intervertebral discs protrusion, recording percentage changes of mri signal intensity and other image characteristic. we will study mri signal intensity of protruded nucleus pulposus, the size of protruded nucleus pulposus, discs hight, neural root compression degree, thicken ligamenta flava, discs degeneration degree, protrusion type and their relation with incident time
本研究擬對已知不同突出時間的腰椎間盤突出患者進行詢問病史、體格檢查和磁共振掃描，記錄臨床表現、突出時間、突出髓核及同層間盤的信號強度、突出髓核大小、突出間盤厚度、有無神經根受壓、有無黃韌帶肥厚、突出間盤變性程度、突出類型等指標，觀察突出時間不同的腰椎間盤的臨床表現及磁共振表現特點，尋找與腰椎間盤突出時間相關的指標，並根據臨床表現及磁共振所見初步判斷腰椎間盤突出的時間。The conclusions from this research include : ( 1 ) the real part mainly effects the delay time between two peaks of gpr signal, the larger the real part, the longer the delay time. ( 2 ) the imaginary part mainly affects the peak amplitude of gpr waveform except that from pavement surface, the higher the imaginary part, the lower the peak amplitude. ( 3 ) the neglect of imaginary part of dielectric will increase the analyzing error obviously when it is higher
分析了路面結構層材料介電常數實部和虛部對雷達電磁波反射信號的影響，並得出以下結論： （ 1 ）介電常數的實部主要影響雷達反射波的時延，實部越大，時延越長； （ 2 ）虛部主要影響除路表反射波幅之外的其它結構層界面的反射波波幅，虛部越大，反射波幅越小； （ 3 ）當介質介電常數虛部較大時，忽略虛部將給分析結果帶來明顯的誤差； 3The potential clinical value of cell proliferation imaging could be to identify treatment " success " or " failure " much earlier than changes in tumor size or volume identified with computed tomography ( ct ) or magnetic resonance imaging ( mr ), or changes in glucose metabolism measured with positron emission tomography ( pet ). this may be particularly important in the evaluation of patients early in the course of treatment, particularly those patients being treated with cytostatic drugs
細胞增殖造影的臨床價值在於腫瘤治療效果成敗?別能早於以電腦斷層掃描（ ct ）或核磁共振造影（ mr ）發現的腫瘤大小或體積變化，或以正子放射電腦斷層掃描（ pet ）所見的葡萄糖代謝變化，這對那些療程使用細胞增殖抑制藥物治療的病人早期評估特別重要。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。In an edt, the electrical power produced is the rate of work done by the magnetic drag ? that is, the magnitude of the drag force times the velocity of the satellite ( relative to the magnetized ionosphere ), which is about 7. 5 kilometers per second in leo
在edt中，生成的電功率等於磁拖曳力做功的速率，也就是拖曳力的大小乘上衛星相對于磁化電離層的速度，在leo上約為每秒7 . 5公里。分享友人
