In this part, the distribution of stable states of a system is worked out under the condition of unbalanced attention parameters on basis of analyzing elementary dynamic equation and synergetic potential function, which improved the discussion of relevant properties of basic synergetic equations. Then, with the analysis of effects of attention parameters in synergetic dynamics, a set of elementary properties are presented to give light how the attention parameters work on pattern recognition process. In the end, in view of geometric sense in synergetic order parameters, some elementary properties are studied, by which a new construction method of order parameters is established so as to provide a general way to constitute new relations of prototype patterns according to practical requirements.
