檢波器的放電時間常數Numerical simulation results indicate that, for low temperature dust particles, dust particles mainly exist in the area near the column center and their charge - number can be considered as a constant, while in the area where there are no dust particles, ion and electrons are in ambipolar diffusion ; for high temperature dust particles, both the distribution regions of dust particle and high ion density are expanded and dust charge - number is increasing with the distance from the center
計算結果表明:當塵埃粒子的溫度較低時,塵埃粒子主要集中在圓柱形放電器的中心很小的區域,塵埃粒子攜帶的電荷幾乎是一個常數,受塵埃粒子空間電荷的影響,離子在該區域的密度最高。在遠離中心區域,離子和電子呈現雙及擴散特點;當塵埃粒子的溫度較高時,塵埃粒子分佈的區域和高離子密度區域擴大,塵埃粒子離放電器中心越遠,攜帶的負電荷越多。A control pulse transmitted to a gate or other digital device to release data at a precise instant, usually by the cpu
一種控制脈沖,通常由cpu在某個準確時間傳輸到門電路或其它數字設備以釋放數據。Cable networks typically offer a number of avails per hour, with two to three minutes of " local " avails per hour given to cable operators to sell locally while the remaining avails go to national advertisers
有線電視公司通常在每小時內提供數個三十秒的廣告時段,其中給地方有線電視播放公司兩、三分鐘做當地廣告,其他時間留給全國各地的廣告商。After the discussion of the numerical simulation method based on the fdtd method and the pml technique, the motions of the charges and the electrical field lines were first employed to describe the radiation procedures of the pulse electromagnetic waves. then the causes of how the charges are accelerated and how the motion status of the charges are maintained were further studied from the angle of interaction of charge and field. after these analyses, it was pointed out that the pulse radiation is due to the suddenly occurred time - varying electrical field ( displacement current ) in the open space. this view was further evidenced by two examples : one is the partly resistance loaded antenna, the other is the partly curved antenna. the radiation procedures of the pulse electromagnetic waves of many different situations were simulated throughout this paper with the contours and waveforms of electric field given. these figures are very helpful to the understanding of the radiation mechanism of the pulse electromagnetic waves
在討論了基於時域有限差分法和完全匹配層技術的數值模擬方法之後,首先從運動電荷和電力線的角度直觀地描述了脈沖電磁波的輻射過程,然後進一步從場與電荷相互作用的角度分析了天線上電荷是如何被加速以及如何維持其運動狀態的,指出了開放空間中突然出現的時變電場(位移電流)是脈沖電磁波輻射的根本原因.文中還對局部電阻加載的天線和局部彎曲的天線進行了研究,以進一步說明上述觀點.對多種情況下的脈沖輻射過程進行了數值模擬,並給出了電場的等高線和空間波形圖,這些圖形對理解脈沖電磁波的輻射機理非常有益Starting with the research on the characteristics of frequency spectra of the ip field as well as charging - discharging time and based on experiment results, the authors summed up frequency spectra, time spectra and decay rate characteristics of sulfide mineralized bodies ( chalcopyrite ) and graphite - bearing dolomitic marble, and detected new parameters for qualitative evaluation of ip anomalies
