| 1. | The o meson enhancement in p - pb and pb - pb relative to p - p collisions is described consistently by luciae
川引人1八门门nn观过程中奇歼粒广， 。 |
| 2. | Ags / bnl and rhic / bnl . this thesis is focused on the study of strangeness production in heavy - ion collisions via luciae model and the j . / polarization at rhic
本论文的主要研究方向分为两个部分，一是sps能区奇异产生的luciae模拟研究，一是rhic能区j /极化的phenix实验研究。 |
| 3. | The collective interaction between strings and the reduced strange quark production mechanism . luciae model can describe the yield and the transverse mass spectra of produced strangeness
Luciae模型包含了弦-弦之间的集体相互作用，产生粒子的次级再散射以及奇异夸克压低的约化机制对奇异产生的影响。 |
| 4. | By widening the width of gaussian transverse momentum distribution in string fragmentation . luciae reproduced the o mesons rapidity distribution , transverse mass distribution , and also the enhancement factor of o meson in pb - pb relative to p - p collisions

| 5. | This thesis is organized in two parts : the first part of this thesis focuses on strangeness production at sps energies . the strange baryon and strange meson pro - duction at sps energies are modeled via luciae model which includes the reseat ter - ing
我们的工作目标主要集中在用建立在强子和弦机制上的高能核反应模型- luciae ，模拟wa97和na49实验中的奇异重子和奇异介子产生的数据。 |
| 6. | The model reproduced the following facts of wa97 experimental data : the yield of strange particles increases with increasing mass and increasing centrality of the colliding system , and also with increasing strangeness content of hyperons in relativis - tic nucleus - nucleus collisions . the simulation of strangeness production using luc1ae model shows that strangeness production is related not only to the rescattering . but also to the collective interaction among strings in relativistic nucleus - nucleus collisions
Luciae模型能很好地描写wa97发表的单奇异和多奇异重子的产额和横质量分布的实验数据，能较好描写wa97实验所揭示的相对论性核-核碰撞中奇异粒子产额随碰撞体系质量、中心度的增大而增加和奇异粒子增强随奇异粒子所含奇异夸克数的增加而增强的实验事实。 |
| 7. | The lund string dynamical model frifiof , luciae model and jpciae model were introduced in the third chapter . luciae model is based on frifiof model , while jpciae model is based on pyth1a . paciae model , a new model based on parton and hadron cascade is being improved and its physical ideas is introduced
论文的第三章主要介绍了建立在lund弦模型基础上的强子和d玄级联的fritiof模型、 luciae模型和jpciae模型，其中luciae模型是建立在frjtiof棋型的基础上，而jpciae模型是建立在pythia的基础之上的。 |
