Aimed at the problems of the timevarying information processing and the dynamic system modeling, two kinds of process neural network models, including the rational formula process neural networks and the process neural ne tworks with time-varying inputs and outputs function,were built in this paper. In the process neural networks with timevarying inputs and outputs function, the time accumulation operator of process neuron was adopted as the integral to time or other algebra operations, its spacetime aggregation mechanism and incitation could synchronously reflect the space aggregation and stage time accumulation effect of exterior timevarying input signals to the output results, so as to com plete the complex mapping relationship between the inputs and outputs of non-linear system. In the rational formula process neural networks, its basic information processing unit was made up of two process neurons which appear dually,and logi cally divided into numerator and denominator, then output after rational formula combining, it can effectively advance the flexile approximation of process neural networks to the process functions which have singular values and the facility of reaction nearby the singular value point. The characteristics of these two kinds of process neural networks models were analyzed in this paper, the concrete learning algorithms were given, the effectiveness of these two kinds of network modes in time-varying information processing was proved by the cases of the process simulation and fault diagnosis of rotating machinery in the oil filed exploitation.
