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。 -
In chapter 3, the non - linear equation was linearized with the jacobi matrix, and then the linearized equation was transformed into fixed frame to analyze the stability problem with eigenvalue method ( on - ground or hovering ) or floquet theory ( forward flight ). meanwhile, the equation was perturbed by sweep frequency excitation from steady state to get transit decay of lag response which was then transformed into fixed frame with a numerical fourier coordination transformation ( fct ). the fixed frame response along with the body response was analyzed via an fft to determine modal frequencies
然後，在穩態響應的基礎上利用雅各比矩陣對非線性方程進行了線化，線化后的方程利用多槳葉坐標變換轉換到固定系下后，利用直接特徵值分析（地面、懸停）或floquet理論（前飛）對系統進行了穩定性分析;同時，對系統進行了瞬態響應分析;在系統達到穩態的基礎上進行掃頻激勵，用fft變換求得系統頻率，進而用移動矩形窗方法分析得到系統的阻尼。 -
In order to simplify the perturbation equation, we assume that the system is homogeneous in equilibrium state and poisson ' s equation describes only the relation between the perturbed density and potential function
為了簡化方程，假定平衡時的系統是均勻的， poisson方程只建立擾動后的密度和勢函數之間的聯系。 -
On the basis of the perturbed karush - kuhn - tucker ( kkt ) conditions of the primal problem, this paper presents a new interior point algorithm to solve power system weighted nonlinear l ( norm ( ipwnl1 ) state and parameter estimation problem
基於原問題的擾動karush - kuhn - tucker （ kkt ）條件，本文提出了一種新的電力系統加權非線性l1范數狀態及參數估計內點演算法。 -
In this perturbed state of mind, with thoughts that could rest on nothing, she walked on ; but it would not do ; in half a minute the letter was unfolded again, and collecting herself as well as she could, she again began the mortifying perusal of all that related to wickham, and commanded herself so far as to examine the meaning of every sentence
她就這樣心煩意亂地往前走，真是千頭萬緒，不知從哪裡想起才好。可是不到半分鐘工夫，她又按捺不住，從信封里抽出信來聚精會神地忍痛讀著寫述韋翰的那幾段，逼著自己去玩味每一句話的意思。
