In this paper, the author investigates the order of a fine focus of a uniform isochronous quartic system. By constructing a Lyapunov function and applying several transformations of the variables, he simplifies the focal values of the origin and gives conditions that the origin is not only a center, but also a composition center. The approach can also be applied to other systems.
