色散衰減
英文
dispersion attenuation-
In section one, we analyze the mechanism of lwi gain, and study the effects of the rabi frequency q of the driving field, the injection rates ratio rb / r ~, the exit rate r0, the decay rates ~ and rab between atomic levels, as well as 3 incoherent pump rate r on the gain without inversion, dispersion and population difference of the system. in section two, we discuss the effects of the detuning of the driving field and the probe field on the gain
在第一節中分析了無粒子數反轉激光增益產生的機制、研究了驅動場的rabi頻率、粒子注入速率比值r _ b / r _ c 、粒子退出速率r _ o 、能級間的自發衰減速率r _ （ c - b ） 、 r _ （ a - b ）和非相干泵浦速率r對增益、色散和粒子數差的影響；第二節討論了驅動場和探測場的失諧對無粒子數反轉激光增益的影響。In this paper the injection dispersion in an oscillatory flow mixer has been studied by using the flow visualization technique with a solution of blue dye as the tracer. the process of injection dispersion was monitored with a digital camera connecting to a computer that treated the video data stream synchronously to obtain the attenuation curve of relative deviation of the flow image ' s gray scale values
實驗採用以藍色有機染料為示蹤劑的流動顯形技術，由攝像頭實時攝取注入分散過程的動態圖像，計算機同步分析視頻流數據，從而以在線監測的方式獲得流場圖像的灰度相對方差隨時間衰減的曲線。Also, any negatively refracted wave would be rapidly smeared out in only a few wavelengths by dispersion, which valanju maintains will always be a major problem in a negative index material
此外，負折射波將在幾個波長內因色散而快速衰減，瓦藍朱認為這將是負折射率材料最大的問題。Then, according to waveguide theory, planar waveguide is analyzed. the main parameters, such as spread constant, decay coefficient, cut - off wavelength and so on, are deduced from dispersion formula of planar waveguide. the distributions of electromagnetic wave in the planar waveguide are obtained also
其次根據波導理論分析了平面波導，由平面波導的色散方程推導出了導模的傳播常數、衰減系數、截止波長等特徵參數以及波導中光波電磁場的分佈。分享友人
