中文摘要：
研究了薄板热扩散中分形生长的控制,给出了生长概率与干扰项之间的数量关系,预测了热扩散分形生长表面在干扰作用区域内的凝聚情况,并随着干扰项的制约而达到控制的目的.其中以三角函数形式的非线性项与定义域为圆域的源项构成的环境干扰项为例,验证了该控制方法的有效性.另外,生长表面的标度维数变化显示了环境干扰项对实际生长复杂度的影响.
英文摘要：
The control of thermal diffusion fractal growth of thin plate in reality under the environmental disturbance is introduced.The quantitative relationship between growth probability and environmental disturbance is obtained.According to the relationship,we predict that the growth surface will aggregate in the region of the environmental disturbance and be controlled by restricting the disturbance.The simulations show that the environmental disturbance,which is composed of a trigonometric function as a nonlinear term and a source term having a round region,controls the growth variation effectively.In addition,the change in fractal dimension of surface growth illustrates that the complexity of the growth increases as the environmental disturbance increases.
