查询词典 exponent

It shows that the critical exponents of conductivity, u, are in good agreement with the mean-field percolation value and in clear disagreement with the universal value in three dimension. This nonuniversal behavior can be interpreted as a result of the interaction between CB and polymer. The influences of the property and volume fraction of CB and radiation crosslinking on conductivity and critical exponent were also studied.

Then, according to phase space reconstruct technique from one-dimensional and multi-dimensional time series, the quantitative criterion and rule of system chaos which combine neural network, analyses, computations and sort are conducted on EEG signals of five kinds of human consciousness activities. The author finds that statistic results of the determinism computation in time series indicate that chaos characteristic may lie in human consciousness activities, and central tendency measure is consistent with phase graph, so it may become one division way of attractor; approximate entropy of different subjects exists discrepancy; correlation dimension and Lyapunov exponent of different consciousness activities indicate that attractors of human activities are all fractional; nonlinear quantitative criterion and rule, which unites neural network, can distinguish different styles of consciousness activity in principle, and the result of sortation takes on that consciousness activity type of arithmetic is distinguished more easily than that of abstract.
