| 摘 要： | 用MonteCarlo方法模拟了三维简立方格点和面心立方格点上的线性高分子模型自踪迹规避(Self AvoidingTrail,SAT ) .求解了SAT的各种临界指数 .所得的结果显示 ,SAT的各种临界指数介于无规行走 (RW )和自避行走 (SAW )之间 .这完全是因为体排斥作用对SAT模型的限制比对SAW的限制要少一些 ,但又比对RW的限制要大一些 .SAT的各种性质介于SAW和RW之间 .因此 ,有可能SAT与SAW不属于同一个普适类

| Abstract: | In this article,the critical exponents of the polymer model Self Avoiding Trail (SAT) in three dimensional simple cubic lattice and face centered cubic lattice have been studied using Monte Carlo simulation method.The results obtained show that the critical exponents of SAT or its behaviors are intermediate between those of SAW and RW,so it is impossible for SAT to belong to the same universal class with SAW. |
