考虑分形生长基元形状的暂缓模型生长

The Growth under Postponed-Growth Modelwith the Shape of a Growing Unit

本文基于数值解Ｌａｐｌａｃｅ场方程，提出了分形的暂缓生长模型，在此基础上比较了考虑分形生长基元形状后各种模型的计算机模拟结果，认为分形生长与生长基元形状有关；暂缓生长模型是在一定的物理背景下提出来的，该模型不同于“η模型”和噪声减小模型。

Based on solving the toplace field equation nunierically and proposins the petponed-growth medel in fractal, the computer simulatu is results under several niedels with the shapo of a grow-ing unit are compared. It can be shown that fractal srowth is related to the shape of a growing unit,and that the postponed-srowth model propoins under a certain physical background is different fromthe ″ηmodel″and the noise reduction medel.
