研究了扩散张量具有非均匀手征各向异性的反应扩散介质中自波纹的性质。导出了这种介质中圆形波阵面的曲率-速度关系。数值模拟证实了这一关系。从理论上预测了螺旋波的角速度与旋转角的强相关性，并用数值方法进行了验证。在计算机实验中对螺旋波之间的长程相互作用进行了预测和观测。(C)2004爱思唯尔B.V.保留所有权利。
We study properties of autowave patterns in reaction-diffusion media with non-uniform chiral anisotropy of the diffusion tensor. The curvature-velocity relation for circular wave fronts in such media is derived. This relation is confirmed by numerical simulations. Strong dependence of spiral waves angular velocity on the angle of chirality is predicted theoretically and confirmed numerically. Long-ranged interaction between spiral waves is predicted and observed in computer experiments. (C) 2004 Elsevier B.V. All rights reserved.
