Influence of quantum interference on profile of atomic sodium emission spectrum
量子干涉效應對鈉原子光譜線型的影響 -
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。 -
Depth profile acquired with aes has shown that excellent emission character owns to the yielding of the surplus la. analysis the active element concentration on the mo - la2o3 - sc2o3 cathode during it heated. results show la and o diffuse rapidly above 1000 ?, but diffusion rate of o gets slow above 1250 ?, so surplus la maybe produce at this temperature
而在高於1250時，鑭含量依然上升，而氧含量變化已經不大，故可以認為這是超額鑭生成的溫度，元素鈧在從800加熱到1290 ，其含量基本沒有變化，說明在這種材料中，鈧元素向表面的擴散不明顯。 -
The factors that have effect on the car ' s emission such as cleaning inside engine, size of three - way catalytic converter and leakage of exhaust system etc have been tested and analyzed, and some related parameters are determined. in order to ensure that the emission meets the requirements of the euro ii standard at one time, to pass the examination of 80000km durability, and to achieve excellent performance indicator while assuring the emission requirements, the design of intake manifold and camshaft profile is optimized, the test of engine performance and car ' s emission and environment performance have been conducted. through comparison by test, it is shown that the carburetor engine after retrofitting to electronic fuel injection engine has achieved good level in terms of emission and performance, and has been upgraded to the same level as the engine of japan mitsubishi and suzuki
