摘要
D0L系统生长的结果一般是自我严格相似 ,是一种典型的分形 .对于现实中非严格的自我相似性现象建模时 ,一般要采用随机L系统 ,但是随机L系统难以保证生长的结果与原D0L系统的结果之间有强相似性 .本文在D0L系统的生长基础上 ,引入单符号随机变异的生长模型 ,以解决理想形态生长与现实之间的差异 ,扩展L系统的表达能力 .
The growing result of D0L system is generally rigorous self-similarity, and it is a typical fractal. For modeling the dissimilating vision of the reality, generally Stochastic L-system is used. But the Stochastic L-system is hard to promise the strong similarity between the result of growing and primary D0L system. The growing model of random variation of single symbol on the growing foundation of D0L system is infroduced to resolve the difference between ideal and the reality form growing, and to describe more graphics than old L-system.
