A new absolute degree of grey incidence and its application

Based on the definition of degree of grey incidence introduced in [1] and inner product, a new absolute degree of grey incidence is given in this paper. Compared with the original method, the new absolute degree of grey incidence nearly has all of properties mentioned in [1], furthermore, the new method is more reasonable on some properties, and is also comprehended easily in geometry. One can obtain a satisfied incidence order by this new method.
