构造了自仿射Ｓｉｅｒｐｉｎｓｋｉ地毯．在自仿射Ｓｉｅｒｐｉｎｓｋｉ地毯中，认为喉管半径服从截断瑞利分布，采用逐次超松弛技术，模拟了自仿射Ｓｉｅｒｐｉｎｓｋｉ地毯中的粘滞指进．计算了粘滞指进分维，结果表明，当粘滞比Ｍ→∞时，指进图样与在自仿射Ｓｉｅｒｐｉｎｓｋｉ地毯中ＤＬＡ模拟的结果类似：当Ｍ＝１时，驱替流体在长标度范围内具有紧凑的结构，且具有稳定的位移．
Constructed from self-afflicted Sierpinski rugs. In self-affine Sierpinski carpets, the throat radius is considered to be truncated Rayleigh distribution and the successive over relaxation technique is used to simulate the viscous fingering in self-affine Sierpinski rugs. The results show that the fingering pattern is similar to the DLA simulation in the self-affine Sierpinski carpet when the viscous ratio M → ∞: when M = 1, Degree of compact structure, and has a stable displacement.
