Utilizing the three - dimension self - similar percolation model , the paper probed into the renormalization group method of grid of non - uniform granular mixtures , and the relationship between stabilization and non - uniform degree was discussed 借用三维自相似渗流模型重正化群方法,讨论了散粒体稳定性与颗粒非均匀程度的关系。
3 . a new tsaw model are proposed , we use the real space renormalization group approach to treat the model on square lattice . the threshold kc and the fractal dimension d are obtained respectively 我们提出了一种新的自回避行走模型(飞蚁模型) ,用重整化群方法计算了该模型的临界值和分形维数分别为kc = 0 . 545069 、 d = 0 . 814909 。
The real - space renormalization group approach is close to fractal and is widely used in geometric phase transition systems without hamilton , for example , percolation model , rock fracture model , flit ant model 实空间重整化群方法与分形有密切的关系,在不具有哈密顿的几何相变系统,如渗流,岩裂,自回避无规行走等模型广泛地被应用。
In the second chapter , combined with the two - dimension triangle lattice ising model , we show the procedures of the renormalization group methods and illustrate how to apply these methods to solve critical exponent in detail 在第二章中结合二维三角形晶格伊辛模型详细地介绍了重整化群方法的步骤以及如何应用重整化群方法来求解临界指数。
The real - space ( or position - space ) renormalization group method is close to fractal and is widely used in geometric phase transition systems without hamilton , for example , seepage , lattice animal and random walk 实空间(位置空间)重整化群方法与分形有密切的关系,在不具有哈密顿的几何相变系统,如渗流,晶格动物,无规行走等广泛地被应用。
In quantum field theory, the statistical mechanics of fields, and the theory of self-similar geometric structures, renormalization is any of a collection of techniques used to treat infinities arising in calculated quantities.
