Usually there are two basic forms of dynamical systems: continuous dynamical systems described by differential equations and discrete dynamical systems described by iteration of mappings.
根据系统变化的规律可分为由微分方程描述的连续动力系统和由映射迭代揭示的离散动力系统。

According to weight coefficient of binary variable, discrete variables can be gradually determined in optimization process, and their discretization can be realized during iteration successively.
In this paper, the discrete samples of the spectre-radiometer were processed by iteration method, and the restoration of spectral distribution was completed.
