摘要
提出了一种构造Ｓｉｅｒｐｉｎｓｋｉ地毯的新方法——映射膨胀法。在Ｓｉｅｒｐｉｎｓｋｉ地毯中，视格点为孔隙，键为喉咙，并认为喉咙半径是随机分布的，采用超松驰技术，模拟了Ｓｉｅｒｐｉｎｓｋｉ地毯中的粘滞指进。结果表明，其指进图像与正方网格中的指进图像有一些不同的性质，例如类十字结构消失、对称性破坏等。另外，还得到了表面分维与粘滞比和无序参数间的关系。
A new mapping dilation method (MDM) is proposed to construct Sierpinski carpet Based on the assumption that bond radius are non uniform distribution,viscous fingering (VF) in Sierpinski carpet have been investigated by means of successive overrelaxation technique The investigation results show that finger pattern in Sierpinski carpet is different from that using square lattice A universal surface fractal dimension formulation on VF in Sieroinski carpet is introduced
