2.Then we can preserve the closure of spatial operations and RSDD spatial data types. For the closure of spatial operations about ROs, we have studied the intersection between RPOs and gained the restructure algorithms, i.e., redraw a RPO-line, reconstruct a RPO-plane, and reconstruct a RPO-solid. We have researched the operations on ROs and obtained the operation algorithms about inserting a RPO-point, a RPO-line, aRPO-plane, and a RPO-solid into a RO.

10.A new method to reconstruct the reciprocal primitive cell has been developed based on crystallographic geometry. Different from the conventional geometric figure|forming method, there is no need for the angles between the reciprocal planes and usually only three diffraction patterns with a row of same reflections are required, which could simplify the electron diffraction operation. The Bravais lattice type and parameters of β-Si-3N-4 has been determined by using this method.
