Facing on the complex electromagnetic environment of electrical equipment, based on the bio-anti-interference characteristics of neuron system, the bio-inspired electromagnetic protection is proposed in order to improve and assist the traditional electromagnetic protection method. In order to analyze the dynamical characteristics of electrical signal transfer process of neuron system, Hodgkin-Huxley (HH) model is adopted to calculate the action potential of single neuron. The initial value problem used in the parameters of Hodgkin-Huxley model is studied in order to satisfy the physiological phenomenon. The stability of HH model is analyzed to assess the dynamic stable performance of neuron. Based on the investigation of single neuron, a simple neuron system consisted of two neurons and one synapse is studied. The compassion between the action potential of posterior neuron and different synapse is performed, which explores how the mathematic models of different synapses influence the action potential. The relationship between action potential of posterior neuron and coupling strength of simplified synapse is calculated to explain the diversity of electrical signal output of neuron system. These numerical results enable to provide some datum for deeply developing the bio-inspired electromagnetic protection and well designing the bio-inspired circuit.

单脉冲刺激下神经元系统动作行为的研究。

针对电气设备复杂的电磁环境，基于神经元系统的生物抗干扰特性，提出了生物启发式的电磁防护技术，以改进和辅助传统的电磁防护方法。为了分析神经元系统电信号传递过程的动力学特性，采用霍奇金-赫克斯利（HH）模型计算单个神经元的动作电位。为了满足生理现象，研究了Hodgkin-Huxley模型参数中使用的初值问题。分析HH模型的稳定性，以评估神经元的动态稳定性能。在研究单神经元的基础上，研究了由两个神经元和一个突触组成的简单神经元系统。在后神经元的动作电位和不同突触之间进行同情，这探索了不同突触的数学模型如何影响动作电位。计算后神经元的动作电位与简化突触的耦合强度之间的关系，以解释神经元系统电信号输出的多样性。这些数值结果可为深入开发生物启发性电磁保护和精心设计生物启发性电路提供一些数据。计算后神经元的动作电位与简化突触的耦合强度之间的关系，以解释神经元系统电信号输出的多样性。这些数值结果可为深入开发生物启发性电磁保护和精心设计生物启发性电路提供一些数据。计算后神经元的动作电位与简化突触的耦合强度之间的关系，以解释神经元系统电信号输出的多样性。这些数值结果可为深入开发生物启发性电磁保护和精心设计生物启发性电路提供一些数据。
