| 1. | ( 3 ) the study of multiparticle dynamics , in 用mc模拟和实验研究发现:能量为91 |
| 2. | Another important phenomenon in high energy multiparticle production is the hadronic jets . the jets are selected using the durham algorithm 喷注事件各向异性动力学起伏的这一特性,为圆锥形喷注的产生提供了一个标度。 |
| 3. | The cut of phase space , particle type , average multiparticle , etc . no dynamical fluctuation has been observed through event factorial moments analysis 可见,通过对事件阶乘矩erraticity的分析,根本就观测不到任何动力学起伏。 |
| 4. | All the simulative results underestimate that of experimental data . this seems that the erraticity analysis of rapidity gaps can be used to check models in multiparticle production 发现模拟结果都与实验结果有较大的偏离;并且两个产生器所得结果也有较大区别 |
| 5. | , the fractal in space - time evolution in high energy h - h collisions is self - affine , which may trace back to the high anisotropy of phase space of multiparticle final states in these collisions 高能强子-强子碰撞多粒子末态的高度各向异性使得时空演化中的分形结构表现为自仿射。 |
| 6. | Making analogy with the " " spin - glass " phase in polymers , peschanski put forward the idea that there exists non - thermal phase transition in multiparticle systems . a parameter xq has been introduced to characterize the non - thermal phase transition 通过类比聚合体中的“自旋玻璃相” , peschanski提出随机级联的多粒子产生过程中存在非热相变,并提出表征相变的特征参数_ q的公式。 |
| 7. | In the second part of the thesis , the non - thermal phase transition in high energy collisions is studied in detail in the framework of random cascade model . the relation between the characteristic parameter xq of phase transition and the rank q of moment is obtained using monte carlo simulation , and the existence of two phases in self - similar cascading multiparticle systems is shown . the relation between the critical point qc of phase transition on the fluctuation parameter q is obtained and compared with the experimental results from na22 文章第二部分中,我们用随机级联模型对高能碰撞中的非热相变作了仔细研究,用montecarlo模拟得到了表征相变的特征参数_ q与矩阶数q之间的关系,证实了自相似多粒子系统中存在两相,求出了相变点q = q _ c对起伏参数的依赖关系,并和na22实验结果进行了比较。 |
