Core-shell nanostructiKes have found broad potentials in a large variety of applications including catalysis, biomedicine, and energy conversion/storage devices [1,2]. The unique structural configuration endows the compos让e a capability to combine advantages of both core and shell materials, and deliver optimized properties through a rational design of the components [3]. Accordingly, numerous research efforts have been directed to the synthesis control of the coating materials to build desired nanoshells. Particularly, silica-based core-shell structures have witnessed enormous success benefiting from the flexible synthesis capability ensured by the Stober process, which provides favorable growth kinetics in solution to build precise configuration of silica nanoshells su让ed for their applications, for example, silica-based nanocapsules for controlled drug delivery [4].

Aiming at region connection calculus (RCC) can only roughly represent spatial topological relations, and have difficulty in representing the distance, direction and so on. Therefore, based on RCC theory, Region Extension and Shrinking Calculus are proposed, and then a formalized metrization method using region as a basic unit is introduced. Based on RESC theory, taking the advantage such as application simplicity and easy realization of gird area method. The experiment proves the spatial relations can be easily obtained by Grid-Region method, and it is an effective way to repre- sent spatial relations.
