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.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
