  1. 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,解析的研究了電子在相對論速調管放大器的調制腔和漂移管中的預群;用粒子波互作用的場方法導出了在輻射腔中預群電子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、多注多間、單注多間和多注多間速調管輸出迴路的諧振頻率、間阻抗實部和外觀品質因數等特性參數。
  2. In the theoretical simulation on the behavior of single helium atom in aluminum, the varieties of energy data including the formation, migration, binding, and dissociation energies for single helium atom at the interstitial, vacancy, grain boundary, and dislocation sites in aluminum lattice were calculated, based on the density functional theories, general gradient approximation and pseudopotential plane wave method. results showed that the most fittable sites for containing helium atoms inside the cell are vacancies. but in the view of the whole lattice, grain boundaries are the best

    計算結果表明,晶內he原子擇優佔位區是空位,而在整個晶體范圍,最有利於容納he原子的區域是晶界,位錯容納he原子的能力次於晶界和空位;在fcc -鋁的間位中, he原子優先充填四面體間位;晶內間he原子是可動的,通過間he原子的運動,可在晶內集,或被空位、晶界、位錯等缺陷縛。
