  3. At the other hand, we can perform the rrpa calculation with the continuum replaced by a set of outgoing single particle resonances, it indicates that the resonances in the continuum play an important role in the description of nuclear dynamical processes, such as collective giant resonances. energies, widths and wave functions of the single particle resonant continuum are determined by solving scattering states of the dirac equation with proper asymptotic conditions for the continuous spectrum in the r ' elativistic mean field theory. the relativistic regular and irregular coulomb wave functions are calculated numerically

    在進行相對論無規位相近似計算時將連續譜中所有的正能態用單粒子共振態來代替,並且在計算中採用單粒子共振態的真實寬度,利用這種方法我們計算了核的同位旋標量巨八極共振響應函數,並且和考慮了連續譜中所有正能態貢獻的結果進行比較,計算結果表明,連續譜中只考慮單粒子共振態對核的集體激發的貢獻時,給出的響應函數基本上能夠重現考慮了所有正能態貢獻時的計算結果,這說明了在核的集體激發中,連續譜中主要是單粒子共振態的貢獻。
  4.

  5. For the expansion theorems of self - adjoint dirac operator, it is difficult to prove it by using the method of integral equation

    對于自伴dirac運算元的特徵展開定理的證明,用積分方程方法有一定的困難。
  6. The condition under which the dirac operator is self - adjoint is discussed under the general linear boundary condition between the interval of two points. for the expansion theorem of non - self - adjoint dirac operator, it is unable to use the method of integral equation. but under the linear boundary condition and unlocal boundary condition, the eigenvalue expansion problems of non - self - adjoint operator can still be discussed by using the residue method

    對于非自伴dirac運算元的特徵展開定理已無法應用積分方程的方法,本文仍用留數方法對一個兩點非自伴邊界條件和一個非局部邊界條件下產生的非自伴運算元的特徵展開問題進行了討論,分別得到了它們的特徵展開定理。
  7. The asymptotic estimations of solution of initial value problem are obtained for dirac equation by use of the transformation matrix operator in this thesis

  9. Lbie, based on the local boundary equation, adopts the traditional moving least squares ( mls ) approximation which depends on only the values of the nodes in the domain of the problem or along its boundary. the whole process of integration is carried on over a local domain or its local boundary centered at the node in question. the local boundary equation can be rewritten to represent the values of the unknown function at the point of interest, and the essential boundary conditions can be directly and easily enforced by using the green formula and the characters of the dirac function

    它以局部邊界積分方程為基礎,採用移動最小二乘近似函數,從而只需要分佈在問題域內及其邊界上的節點的信息值,無需劃分單元;整個積分是在以節點為中心的局部域及其邊界上實現,所以不需要背景積分網格;藉助于格林公式及dirac函數的性質,將局部邊界積分方程轉化為所考慮點的未知函數的邊界積分表達式,便於直接施加本質邊界條件。
