By　taking　neuraxon　Ranvier　node　circuit　model,　magnetoencephalography　(MEG),　and　consistency　principle　of　fields　and　electronic　circuits　theory　into　account,　the　rationality　and　necessity　of　extending　famous　Hodgkin-Huxley　first-order　static　equivalent　circuit　to　two-order　dynamical　circuit　are　discussed.　Furthermore,　the　frequency　property　of　membranous　capacitance　C　and　inductance　L　of　electrophysiology　material　parameters　are　also　studied　with　a　detail　calculating　case.　The　experimental　results　show　that　the　quicker　the　myelinated　nerve　fiber　transmits　the　signal,　the　smaller　the　membranous　capacitance　and　inductance　values　are.
