摘　　要：利用北京谱仪（BES）在3．55GeV附近采集的数据和国际上已发表的数据，研究了北京正负电子对撞机（BEPC）能区强子事例形态特征的分布，对LUND模型的JETSET7．4产生子作了仔细研究，并得到与低能实验数据相符的模型参数．Using hadronic events sample collected around 3.55 GeV with Beijing Spectrometer (BES) at Beijing Electron Positron Collider (BEPC) and the published data, we studied distributions characterizing the hadronic events produced from the e+ e- annihilation and the most sensitive parameters in the LUND model and found that the characterizing distributions of the hadronic events of the BEPC data agree well with that predicted by the LUND model with tuned parameters.
