使用激光轮廓仪研究了由脊而碎片纸片形成的网络。将纸的方形纸弄碎成球，展开，并测量其高度轮廓。从这些概况中，提取了施加的脊作为网络。节点被定义为脊之间的相交，而连接节点连接节点。已经研究了许多网络和空间特性。发现山脊长度分布的尾部遵循功率定律，而较短的脊则遵循对数正态分布。发现该度分布具有指数衰减的尾巴，并且发现该度相关性是分离的。还研究了由山脊和节点形成的沃罗诺伊图创建的方面。
The network formed by ridges in a straightened sheet of crumpled paper is studied using a laser profilometer. Square sheets of paper were crumpled into balls, unfolded, and their height profile measured. From these profiles the imposed ridges were extracted as networks. Nodes were defined as intersections between ridges, and links as the various ridges connecting the nodes. Many network and spatial properties have been investigated. The tail of the ridge length distribution was found to follow a power law, whereas the shorter ridges followed a log-normal distribution. The degree distribution was found to have an exponentially decaying tail, and the degree correlation was found to be disassortative. The facets created by the ridges and the Voronoi diagram formed by the nodes have also been investigated.
