我们分析了鱼和哺乳动物的热感受器模型的相空间结构。作为温度的函数，我们确定了在低温下周期加倍的情况，一个不稳定的固定点与吸引子碰撞并阻塞热感受器的状态，以及随着温度进一步升高从周期n+1过渡到周期n。周期减少现象是由于快慢离子通道之间的自共振，并显示出典型的模式锁定特征。
We analyze the phase-space structure of a model for thermoreceptors in fish and mammals. As a function of the temperature we identify a period doubling scenario at low temperatures, a regime where an unstable stationary fixed point collides with the attractor and blocks the thermoreceptor, and a transition from period n+1 to period n as the temperature is further increased. The period reduction phenomenon is due to an autoresonance between fast and slow ion channels and shows the features typical for mode locking.
