From the perspective of visual design， to explore the diachronic form of two-dimensional space，as well as the influence to modern design field. Based on the theory of diachronic， it studied the relationship between time and space of static or movement of the visual design. It put forward multidimensional schema and schema of the static design continuously diachronic form; the diachronic form of displacement movement and the interactive process of motion design， and from the contradictions of the three-dimensional space and two-dimensional space form of space design duration. Now diachronic permeated gradually along with the development of research in the field of visual design， and became more and more important factor in the design field.
