Adopting the assummation that the quark interaction is the sum of the usual one - gluon direct exchange and the mixture of linear scalar and vector potentials, we structure the relativistic corrections of order v2 / c2to the cornell potential, including the annihilation potential for the quark and antiquark of the same favors which plays the same role with the one - gluon direct exchange at short distances. the effects of the relativistic corrections on the hyperfine splittings of quarkonium states are discussed, and a good fit to the available experimental data is obtained on heavy quarkonium mass spectra
采納庫侖勢源於單膠子直接交換，而線性禁閉源於標量和矢量的混合，同時考慮在短程區域與單膠子直接交換起同樣作用的同味正反夸克的湮滅，構造了靜態夸克-反夸克勢到v ~ 2 c ~ 2級次的完全相對論修正，並擬合計算了重介子偶素的能譜，討論了相對論修正對重介子偶素能級分裂的作用。In this article, introduce the important meanings of a - b effect, first is a have physics factors, second is wave function phase factor is connected with geometrical factor in ( b = 0, a 0 ), through a - b effect, we know : electromagnetic field vector e, b is local quantity, electromagnetic potential a, is global quantity, adding a, description and by the way of loop integral, electromagnetic field " effect is completely descripted
本文介紹了有重要歷史意義的a - b效應， a - b效應揭示了兩點物理觀念的變革：一是電磁矢勢有物理效應。二是在無場強但有磁矢勢（ b = 0 ， a 0 ）的區域，波函數的相位因子與其運動空間結構有關。 a - b效應顯示； e 、 b是局域量， a 、是總體量，只有加入a 、之後的描述，並通過a的環路積分，才能對電磁場的作用做出完全準確的描述。Especially it stresses the method of modeling 3d terrain landscape using dem & digital remote sensing image based on opengl and the implementation of vector image subsystem for planning and editing railway line
主要介紹了基於opengl利用數字高程模型、數字遙感影像重建三維地形景觀的方法、用於鐵路設計的矢量圖形子系統，並在此基礎上開發了數字鐵路選線系統。However, the dirac structure of the nucleon self - energy in the dbhf can not be explicitly obtained in a numerical calculation. therefore a reliable decomposition of the dbhf g matrix is desirable, which is significant for the extraction of effective interactions, especially for the isospin dependence of the effective interactions
然而，在該理論方法中，如何合理地給出dbhf自能的dirac結構對于有效相互作用的提取，特別是同位旋矢量介子有效相互作用耦合常數的提取是十分重要的。This paper presents the overall structure, design idea and systematic function and application condition of information analysis and management system on hydrology and sediment of the yangtze river and mainly introduces function realization of 8 sub - systems of editing sub - system of vector data, management discipline of object relation database, computation sub - system of hydrology and sediment sub - system, visualized analysis sub - system of water and sediment information, analysis sub - system of the yangtze river channel evolution, inquiry sub - system of fundamental information, 3 dimensional visualized sub - system of the yangtze river, network publication sub - system of hydrology, sediment and river channel information
