Soon after that , other researchers adopt this idea to investigate critical phenomenon . they realized that the renormalization group method is a new scheme to research critical phenomenon 随后一些研究者也采用重整化群方法研究临界现象,发现重整化群方法是一种很好的研究临界现象的方法。
This way seems to avoid partition function conceptively , but study the transformation which makes partition function unchanged . these transformations are made up of renormalization group 这种方法从概念上看它回避直接求配分函数,而代之以研究使配分函数保持不变的变换,这些变换构成所谓重整化群。
When dealing with a low swirl number flow , the results by renormalization group ( rng ) k - ? model agree well enough with experiments , so we do not have to apply reynolds stress model ( rsm ) 在计算弱旋气相流动时, rng ?模型可以满足工程上的精度需求,因而没有必要运用计算量很大的雷诺应力模型。
These values are the critical exponents of three - dimension site - lattice . we study the two - dimension triangular - bond lattice percolation with next - nearest - neighbor interactions on the renormalization group approach as well 另外,我们采用位置空间重整化群方法,对二维次近邻三角格子键渗流模型进行了研究。
This theory is based on a model for how the structure on one length scale l is related to that on another scale m , with the implicit assumption that the structure is invariant under the renormalization group scale transformation t ( x ) 该方法假定在标度变换下系统的结构不变,讨论在长度标度l与l下系统结构的关系。
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.
