In the thesis, the design method of the diagonal flow fan impeller has detailedly researched different from the previous means borrowing and extending design methods for axial flow or centrifugal type, a complete design method has presented on the basis of quasi - three dimensional design idea. the course is mainly composed of such steps as meridional surface design, inverse problem computation in meridional surface, blade shaping on stream surface, and verifying through three dimensional computation, until the design requirement is met at last
不同於以往的軸流式或離心式延長設計方法或經驗方法，本文按照準三元設計的思路給出了一套完整的設計方法，即子午面設計?子午面反問題計算?斜流流面上葉片造型?三維計算驗證優化，直至符合設計目標。 -
Thirdly we introduce the superlattice model with alternating site energies which is more complicated than the simple tight - binding model, and moreover we explore the influence of the alternating diagonal term in hamiltonian on the quasi - energy bands and dynamics
接著引入更為復雜的格點能交替變化的超晶格模型，並在此基礎上考察了hamiltonian中交替變化的對角項對準能譜與動力學的影響。
