Then using the matrix, the accumulated generated grey exponential law about the sequence is proved.

On the basis of it, the criteria of the grey exponential law of a discrete function are obtained, i.

Determination of the power law exponent of polymer solution in condition of oil reservoir;

The influence of Weissenberg number and power law exponent on the flow field is analyzed .

The influence of Weissenberg number and power law exponent (n) on the flow field is analyzed.

The white exponential law coincidence property is adopted into the load forecasting method to solve the problem that the model cannot be used when the developing coefficient is large.

In the paper, the criterion of the white exponential law of a discrete function is given after discussing the necessary and sufficient conditions of a continuous function being an exponential function.

The new method overcomes the defect that the old method has not possessed the white exponential law coincidence property.

This paper is taking 1/e as standard model,discussing physical meaning and importance of 1/e in electromagnetism, putting an any space-time coordinate of the even change physical problem that according to exponential law attenuation is taken consideration instead of the uneven change physical problem, and by 1/e, it have revealed some essential characteristic in physical process.

Based on the basic idea of adaptive variable structure control (AVSC), this paper deduces the reaching condition of adaptive sliding-mode, and proposes three laws according to which the slope of a switching line change: linear law, power law and exponential law.

According to the particularity and complexity of middlerange airtoground missile s descending process,this paper provided a descending ballistic trajectory scheme based on the method which let the missile first descend quickly according to fixed obliquity,then turn to exponential law for smooth transition to cruise process.
