摘　　要：为了准确仿效生物神经脉冲信号的波形特征,提出并论述1/2阶网格型模拟分抗电路模型,1/2阶网格型主值分抗电路与T型、Π型、桥T型主值分抗电路之间的等效转换,用晶体谐振体和差接变量器实现它的方法,1/2阶网格型模拟分抗电路模型的频率特性以及用模拟分抗电路构造任意分数阶仿生神经型脉冲振荡器。实验中,以1/2阶网格型模拟分抗电路为例构造了1/2阶仿生神经型脉冲振荡器,其输出的仿生神经脉冲信号比较正确地模仿了实际生物神经脉冲振荡信号的波形特征。The net-grid type analog fractsnee circuit for 1/2 order fractional calculus was put forward and analyzed. The equivalent conversion between T type,Ⅱ type,T type primary fractanee circuit and 1/2 order net-grid type analog primary fractance circuit, the equivalent conversion between syntony crystalloid, cross-linked variable transformer and 1/2 order net-grid type analog primary fractance circuit,and the frequency characteristic of 1/2 order net-grid type analog fractance circuit were disserted. Any fractional order bionic neural-type pulse oscillator was generated with analog fractanee circuit. The results of computer simulation showed that the fractional order bionic neural-type pulse wave accurately simulates actual biology neural-type pulse wave＇s shape characteristic by and large.
