A FitzHugh Nagumo(FHN) neural model,which is double singular stochastic system, is studied.The effects of parameter β,which marks the singular degree of stochastic force at singular point, on the phase transition of the FHN model are discussed when β is non integer.It is shown that the parameter β plays an important role in phase transition of the system, and the...

研究了一个具有双奇异随机性的 Fitz Hugh-Nagumo（ FHN）神经模型 .用参数β表示随机力在奇异点的奇异程度 ,当 β为非整数时 ,研究了奇异参数对 FHN模型相变的效应 .结果表明奇异参数β在 FHN系统的相变过程中起着十分重要作用 ,同时存在锁定现象
