  1. 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。
  2. From maxwell equations the refractive index equation and hamilton - jacobi equation, which describe the evolution of the electric field, are derived including the effects of the diffraction, the third - order intensity - dependent nonlinearity, plasma defocusing, the focusing and defocusing of the plasma channel, and the relativistic self - focusing

  3. The basic principle, main properties, typical parameters, technical characteristics and general situation of klystron are introduced. the electron beam prebunching in the modulated cavity and shift tube of relativistic klystron amplifer ( rka ) is studied analytically, a self - consistent equation of radiation generated by the prebunched electron beam in the radiation cavity is derived using the field method of particle ? wave interaction instead of the electrical circuit method, and in terms of it, the gain in the linear regime calculated, a field analysis method is proposed. the theory analysis shows that the characteristic parameters, such as resonance frequency, real part of gap - impedance, external quality fadtor in all kinds of klystron output circuits including single - beam, multi - beam, single - gap, multi - gap, single - beammulti - gap, multi - beam multi - gap klystron output circuit, can be calculated by the field analysis method

    本文系統的介紹了速調管的工作原理、主要特點、發展概況、主要性能指標和技術特點，解析的研究了電子束在相對論速調管放大器的調制腔和漂移管中的預群聚;用粒子波互作用的場方法導出了在輻射腔中預群聚電子束產生輻射的自洽方程，同時對線性區的增益進行了計算。理論分析表明，場分析法可用於計算單注單間隙、多注多間隙、單注多間隙和多注多間隙速調管輸出迴路的諧振頻率、間隙阻抗實部和外觀品質因數等特性參數。
  4. In the theoretical framework of the relativistic mean field, the influences of ( superscript - ) meson condensate on the equation of state and the particle fractions of neutron star matter including delta isobars are studied

    摘要在相對論平均場理論框架下研究了（上標- ）介子凝聚對包括共振態的中子星物質狀態方程及其粒子分佈的影響。
  5. The method can describe the relativistic dynamic behavior of particles accurately and is especially adaptive to simulate the dynamic behavior of particles in ultra - intense laser field. 2. a charge conserving current weighting algorithm, which is based on the current conservation equation, is used in the code

    該程序的主要特點是對粒子模擬中的一些演算法進行了優化，主要工作包括： 1 、將等離子體粒子模擬中得到廣泛應用的borris旋轉推動粒子方法進行了改進。
  6. Thus ， for instance ， it may come as a shock to mathematicians to learn that the schrodinger equation for the hydrogen atom is not a literally correct description of this atom ， but only an approximation to a somewhat more correct equation taking account of spin ， magnetic dipole ， and relativistic effects ； and that this corrected equation is itself only an imperfect approximation to an infinite set of quantum field - theoretical equations

    因此，舉例來說，對數學家而言，了解到下述情形可能會令其驚愕不已，即薛定諤（ schrodinger ）的氫原子方程式並非是對該原子作出的一種絕然正確的描述，而僅僅是個近似值，趨近於一個在某種程度上更為正確的將自旋、磁性偶極子、以及相對論效應考慮在內的方程式；而這個得以糾正的方程式就其本身而言也只是一個不完美的近似值，趨近於無窮無盡的一整套量子場論方程式。
