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 采納庫侖勢源于單膠子直接交換，而線性禁閉源于標量和矢量的混合，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，并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。 |

By comparing theoretical predictions with experimental data , one can obtain a valuable information on the form of the qq interaction potential . such information is of great practical interest , since at present it is not possible to obtain the quark - antiquark ( qq ) potential in the whole range of distances from the first principles of qcd 夸克勢模型是其中重要的模型之一，它不僅能研究強子的基態，而且能研究激發態，但是，源于在中和大距離與qcd真空的復雜結構有關的非微擾特征，還不可能獲得整個距離范圍內的夸克?反夸克相互作用勢。 |

This thesis studied the dynamical fluctuations inside the single jets in 2 - jet events and the quark and gluon jets in 3 - jet events carefully to explore the dynamics of strong interaction . the dynamical fluctuations inside the single - jets , the quark jets aad antiquark jets are studied using monte carlo method respectively 本文對e ~ + e ~ -碰撞產生的2 -噴注事件中的單噴注子樣本和3 -噴注事件中的夸克噴注及膠子噴注子樣本內部的動力學起伏進行仔細地研究 |

But about 50 trillionths of a trillionth ( 5 10 - 23 ) of a second later , all the quarks , antiquarks and gluons recombine into hadrons that explode outward into the surrounding detectors 但在兆兆分之50 （ 5 10 - 23 ）秒后，所有的正反夸克與膠子就又重新結合為強子而向外爆發，進入周圍的偵測器中。 |

A quark ( or an antiquark ) from the projectile hadron radiates a virtual photon on impact on the target , the photon subsequently decays into a lepton pair 入射強子中的一個夸克(或反夸克)在靶的作用下輻射出一個虛光子，虛光子再衰變成正反輕子對。 |
