  • 简介:在这份报纸,我们首先在帖子上描绘分数维的插值函数(FIF)的有限批评有限自我类似的集合。然后,我们在Sierpinski垫板(SG)上与一致垂直可伸缩因素学习FIF的拉普拉斯算符。作为应用,我们证明SG上的下列Dirichlet问题的答案是有一致垂直可伸缩因素1/5的FIF:u=0在SG上{q1,q2,q3},和u(qi)=i,i=1,2,3qi,i=1,2,3,是SG的边界点。

  • 简介:平行的Liesegang模式猛抛当包含的答案一同沉淀时,乐队们被获得在一个1D胶化矩阵的离子interdiffuse。形成的节俭地可溶的盐,显示磁盘的美丽的层化猛抛对1D试管轴垂直。Liesegang结构从他们的分数维的性质的观点被分析。几何Liesegang模式与象时间,乐队间距和乐队宽度法律那样的著名实验法律在一致被构造。扩散的起始的集中上的乐队间距的依赖(外部)并且不动(内部)电解质(一0并且B0,分别地)被拿跟随Matalon-Packter法律。数学分数维的尺寸和盒子计数尺寸是计算的。分数维的尺寸被发现与增加A增加0并且减少的B0。我们也与雏晶的随机的分发分析马赛克模式,在他们的分数维的性质上比古典Liesegang胶化方法,和报告在不同条件下面成长。最后,乐队在多重谱线被组织的复杂Liesegang模式被学习,并且分数维的性质与复合增加,这被显示出。
