摘要
The method of calculating numerically the Lyapunov exponent of partial differential equations is stated. The mean Lyapunov exponent and the local Lyapunov exponent are introduced in order to characterize the systems described by the partial differential equations. it is shown that the mean Lyapunov exponent expresses clearly how disordered the spatial patterns are.
