我们数值研究细胞间的电导如何影响耦合的可兴奋细胞阵列中的螺旋破裂过程。细胞动力学由Aliev-Panlov模型描述，细胞间的连接通过欧姆元件进行。我们发现，降低细胞间电导可以防止螺旋波分解成一个复杂的时空模式。我们研究了这种效应的机制，并表明，崩溃消失，因为增加了初始螺旋波的舒张间期。
We study numerically how the intercellular conductance affects the process of spiral breakup in an array of coupled excitable cells. The cell dynamics are described by the Aliev-Panlov model, and the intercellular connection is made via Ohmic elements. We find that decreasing intercellular conductance can prevent the breaking up of a spiral wave into a complex spatiotemporal pattern. We study the mechanism of this effect and show that the breakup disappears because of increasing the diastolic interval of an initial spiral wave.
