Neural cell adhesion molecule L1, discovered in the 80s, is one of the matters that can promote nerve regeneration. It can mediate the interaction of cell-to-cell and cell-to-matrix, take great efforts on neurite outgrowth and fasciculation, migration of neural cells, formation of the myelin, structure of neural trace, transmembrane signal transduction, inhibiting apoptosis of neural cells, even on immune system and formation of the tumor. Li is discovered on the mouse's Cerebellar membrane primarily. Thereafter, it also is found in post- mitotic neurons, pre- and non-myelinating Schwann cells and so on.

In this paper, we first analyze the mechanism of action potential propagated alongan unmyelinated fiber, and present a hypothesis that the velocity of transmembranecurrent is the equivalent of the propagation velocity of action potential. Then usingthe H-H model and the cable equation we obtain the formula of the velocity. Insuccession, we apply a similar method to analyze the mechanism of action potentialpropagated along a myelinated fiber. Using the McNeal model and the CRRSS model,we obtain the formula of the velocity.
