當停電時，人們在搖曳不定的燭光下暗中摸索.因沒有紅綠燈的指示，汽車在道路上遲疑不前:冰箱也停止工作，導致食物變質。The ratio of light conductivity to dark conductivity of the nv - si / a - si : h photoconductor is 103, and the light conductivity of nc - si / a - si : h photoconductor in the normal is 2 - 4 times more than that in the lateral
這種nc - si a - si ： h光導膜具有柱狀結構，薄膜的光暗電導比達到10 ~ 3 ，其縱向電導率是橫向電導率的2 4倍。In the lclv, the most important parameter, switching ratio of the lclv, is analyzed. it is mainly influenced by the dark - conductivity, ratio of light - to dark - conductivity, thickness of the photoconductor and the thickness of the liquid crystal. it is concluded that the switching ratio can be improved by matching the thickness of the liquid crystal and the photoconductpr, and the proper change region of the light conductivity of the photoconductor
在電學匹配方面，我們對光電導材料的暗態電阻、亮暗電導比、厚度以及液晶的厚度等對光閥開關比的影響進行了分析，認為液晶光閥開關能力的提高很大程度上取決于光電導層和液晶層的厚度匹配，以及光電導層的電導變化的區域位置。It is found that the fwm field can cause the asymmetry of electromagnetically induce transparency profile. in addition, the effect of different propagating orientations of probe field on the electromagnetically induced transparency is also discussed. in the molecular multi - level system with the perturbed superposition levels, we discuss the electromagnetically induced transparency, spontaneous emission enhancement, double dark resonance and double electromagnetically induced transparency by using the density matrix equation under weisskopf - winger approximation and dressed - state density matrix equation
針對實際的實驗條件，考慮了一種影響量子干涉的新的因素-四波混頻場，研究了四波混頻場對雙光子探測的-型能級體系的eit的影響，發現四波混頻場能夠導致雙光子探測的eit線型的不對稱，在此基礎上，討論了不同探測場的傳播方式對eit的影響，針對分子中實際存在的包含有微擾能級的不同多能級系統，我們分別採用綴飾態繪景下的密度矩陣方程和weisskopf - wigner近似下的密度矩陣方程詳細地討論了電磁感應透明、自發輻射的干涉相消和相長、雙暗態共振和雙電磁感應透明現象。Then, the auxiliary fields fdtd is used to the periodic structure made of dispersive material, such as the pyramid absorbers in anechoic chamber. the permittivity vs frequency property of the absorber is approached by some dispersive equation model, such as debye model and lorentz model, so the broadband response of the absorber can be gotten through one calculation
然後將輔助場fdtd應用到色散媒質周期結構中，導出了色散媒質中的迭代式，並以暗室吸波材料陣列為例進行計算，提出用某一類型的介電常數色散函數（如debye型、 lorentz型等）來逼近材料的介電常數頻率特性的方法，從而可以對吸波材料進行一次性寬頻計算。Based on the universal theory of one - dimensional steady state photorefractive solitons, this paper describes all kinds of one - dimensional steady state spatial solitons in the photorefractive or photovoltaic - photorefractive medium with or without a resistor in the external circuit. the steady - state solutions of the evolution equation are given and then the physical properties of the photorefractive solitons are discussed
依據穩態光折變空間孤子的統一理論，推導了光波在帶有分壓電阻的光伏或光伏光折變晶體小的傳播方程，利用數值方法求解了此方程的明、暗孤子解，討論了三種穩態光折變孤子的物理特性。分享友人
