脱硫剂煅烧后的多孔结构是具有自相似性的分形结构。
The structure of calcined sorbents is a porous system with self-similarity characteristic.
然而，岩石断裂表面粗糙度一般不具有自相似分形性质。
Since natural fracture surfaces in rocks rarely display self-similar property, the estimated fractal dimension of surface roughness surffers from the scale effect.
特别研究了具有自相似结构的幻曲面，从而揭示了一类新的分形。
Especially, the magic surfaces with properties of self-similarity are investigated and a new class of fractal is announced.
