我们用递归传递矩阵算法计算了三维伊辛模型的高温展开，并将自由能展开扩展到24阶。用非齐次微分Pade法和比值法求出比热的临界指数为[α]=0.104(4)。
We compute high-temperature expansions of the three-dimensional Ising model using a recursive transfer-matrix algorithm and extend the expansion of the free energy to 24th order. Using inhomogeneous-differential Pade and ratio methods, we extract the critical exponent of the specific heat to be [alpha]=0.104(4).
