Abstract: Chaos viscosity which was considered in the previous paper is extended so that the decomposed components of the nonlinear term have a periodic motion. The results are given so that the friction due to chaos is decreased by the share of the periodic motion. This is very reasonable because the component of the periodic motion does not contribute to the friction. The chaos viscosity is expressed explicitly by the use of the function of the nonlinear term in the equation of motion. Furthermore, the power spectrum for the chaotic system is given. The periodic motion component affects this spectrum.
