近年来，作者研究了线性和星形支化模型链的大小和形状作为功能（臂数）F和链长（珠总数）N的函数，用于几个晶格和非晶格随机行走模型以及自避免随机行走（嵌入在四面体晶格中）受到各种热力学条件。不仅平均值-在给定长度，功能和热力学条件下的大量配置的平均特征量-已被计算，而且形状参数的分布，并已探讨了大小和形状之间的相关性。本专题文章在原则上总结了这些结果，然而，部分数据是重新计算的更大的样本量和链长度在基础文件。除了F = 4、8和12臂的恒星外，还介绍和讨论了迄今为止尚未发表的关于F = 3、F = 6和F = 10臂的恒星的研究。
In recent years the author investigated the size and shape of linear and star-branched model chains as a function of functionality (number of arms) F and chain length (total number of beads) N for several lattice and off-lattice random walk models as well as for self-avoiding random walks (embedded in the tetrahedral lattice) subjected to various thermodynamic conditions. Not only mean values - characteristic quantities averaged over a large number of configurations of given length, functionality and thermodynamic conditions - have been computed, but also distributions of shape parameters, and the correlation operative between size and shape has been explored. The present feature article in principle summarizes these results, however, the data given in part are recomputed for still larger sample sizes and chain-lengths as in the underlying papers. In addition to stars with F = 4, 8 and 12 arms, so far unpublished investigations on stars with F = 3, F = 6 and F = 10 arms are presented and discussed.
