The paper first summarizes some basic performances of the neuron

gives the new explanation for the Hebb ’s law modifying the strength of the synapse control

obtains the conclusion that the timespace summation of neuron is only intermittant working. An artificial neural net is derived by directly simplifying the Hodgkin-Huxley equations governing the neuro. Lastly

an example is given that the multi-layer neural networks can realize the exclusive or assortment. This model has the primary performances of neuron

for example

the summafion

the latency and the refractory period.In addition

the model can be easily implemented by hardware and software in engineering.
