摘　　要：本文研究了ｅ￣＋ｅ￣－→强子反应中的粒子关联。首先研究多重数关联，然后研究由全同玻色子的Ｂｏｓｅ一Ｅｉｎｓｔｅｉｎ对称性引起的关联。最后，作者提出一种新的源分布一Ｑ￣－ｖＫ＿ｖ（Ｑ）分布，据此研究ｅ￣＋ｅ￣－湮没的Ｂ一Ｅ关联，并与实验数据比较，得出正负电子湮没中粒子关联的相关结论。The particle correlation in e￣+e￣- annihilations are studied in this paper。The multiplicity correlatlons are studied first.Then Bose-Einstein correlation of sym-metrisation of identical bosons are studied. finally.Finally,authors have proposed a distribution of source-the distribution.Q￣(-ν)k_ν(Q).According to the distribution,the Bose-E-instein correlation in e￣+e￣- annihilations are studied,and the experimental data are com-pared with.The conclusions on particle correlation in e￣+e￣- annihilations have been ob-tained.
