Using the parameter-transformation method proposed by Stinchcombe R B, the phase transitions and critical properties of the Ising model on a family of diamond fractal lattices are investigated. It is found that the results are the same as that by using renormalization-group method.

采用英国著名学者Stinchcombe提出的理论方法&参数变换，研究了一族钻石分形晶格上Ising模型的相变和临界性质，结果表明：与实空间部分格点消约（decimation）RG变换的结果完全一致。
