With the use of the average excitation energy approximation and the closure approximation, the solution is reduced to a time - dependent operator acting on the " bare " atomic state
利用平均激發能近似和完備關系，可將此波函數簡化為一個含時的相乘算符作用於無場時的「裸原子」態上。 -
Based on the theory of molecular set nests and prime elements set nested in [ 67, 68 ], with the cuted set f and jm, we have obtain the equivalent theorem, the decomposition theorems, the representation theorems about l - smooth co - topology, the equivalent conditions of constructing a - smooth co - topology by a family co - topologies and the equivalent theorem of closure operator. we have proved that - smooth closure operator is reasonable, discussed the relations between - smooth closure operator and closure operator, - smooth continuous goh and continuous goh, and given a kind of product of - smooth topological molecular lattices
藉助文[ 67 ， 68 ]中提出的分子集合套和素元集合套理論，結合文[ 83 ]並以截集蘆f _ [ a ]和f ~ [ a ]為工具刻畫l上smooth余拓撲f ，從而給出了l - smooth余拓撲的刻畫定理、分解定理、表現定理和由余拓撲族構造l - smooth余拓撲的充要條件 -
And beginning with a perturbed nls equation, using a multi - scales perturbation expansion, we get the zero order and the first order equations, discuss the eigenstates of the operator in the equations, induct relevant " derivative states ", form the completeness of the bounded eigenstates of the associated operator in li space, and expand the corresponding parameters in the closure, get a series evolution equations of the coefficients in the expanded formulas, find the first order approximate solution by researching the evolution equations. this paper also gives the basis of this method - the completeness we have formed and the singular perturbation technique
） dinser方程的求解問題，討論了自伴運算元的本徵函數的正交性和完備性，介紹了尋求微分方程的近似解常用的攝動方法，並從帶有某種擾動項的nls方程出發，利用多重尺度的攝動方法得到了方程的零級近似方程和一級近似方程，通過對近似方程中運算元的特徵態的討論，引入適當的「導出態」 ，建立了運算元在l _ 2空間的特徵態的完備性。 -
