书法创作是书法审美意象迹化的过程,贯穿其中的是意象思维。动型字势系统是推动书法审美意象从“未形”向图像迹化的重要一环。在具体的书法创作过程中,动型字势系统呈现出同心、离心、向心三种变异模式。从动型字势系统变异的幅度上看,可以分成极限和合宜两类。意象思维对动型字势系统的调控就是要达到合宜的状态和效果。 Calligraphy creation is the process of aesthetic trace of calligraphy, which runs through imagery thinking. Movable system is to promote the momentum of calligraphic aesthetic image from “not ” to image trace an important part. In the process of the concrete calligraphy creation, the system of dynamic-type potential shows three modes of variation: concentric, eccentric and centripetal. From the perspective of the magnitude of the variation of the system of passive-type potential, it can be divided into two categories: limit and fit. Image thinking on the dynamic system of word control is to achieve the appropriate state and effect.
