Abstract:
      Stage features of sandstone specimens are studied by a nonlinear dynamics method of Kolmogorov entropy.Comparing research results from power spectra and Kolmogorov entropy to three stages of forepart,rear part and whole process of strain-stress curves,the paper finds that Kolmogorov entropy method is satisfied even more.The method produces a new approach to value system state quantitatively and is a good supplement to power spectra method.Conclusions of the paper have theoretical sense to nonlinear dynamics.
