While, the theory of spatial relationships of hyper graph model is improved. It can solve the problems on the spatial relations in space-time object and the relations among spatiotemporal objects.
而对超图模型空间关系理论的改进更好地解决了时空对象的空间关系和时空对象之间关系的问题。

In this paper, a new data structure of graph, double list, is presented. It is more flexible than other data structures of graph and shows better time and space complexity in graph algorithms.
