Abstract:

The dynamic characteristics of P-sets are discussed on the basis of P-sets’ definition. The conception and the theorems of the P-sets’ family are obtained. GivenP-expansion degree, a dynamic recognition measurement, and the changing extent of P-sets couldbe expressed with numbers. The theorems of P-sets’ recognition and screening are obtained. These theorems could be used to recognize and detect the state of a system.

Key words: P-sets;　P-expansion degree;　P-sets’ family;P-sets’ recognition
