Results and conclusion: the mathematics mechanism theory of Nervous system about their basic data and interconnection may be expressed by the neural information encoding formulation: x1=m1a/b and y1=n1c/d、x2=m2b/a and y2=n2d/c The neural information encoding formulation have novenary and undecimal and many other scales. All Periphery Nervous- Cerebral Cortex- Sympathetic Nervous have obvious and invisible encoding data in 2 kinds: yin and yang ,2kinds:ambulatory and static state, 3 grades: Max Med and Min. they all exist in obvious or invisible type. Just like a cogwheel system and there is a inter-meory function among the data.
