Structure Transformation of Irregular Information for Time-sequence and Elaborate Analysis of Evolution

Ouyang Shoucheng,Zhang Kui,Hao Liping,Zhou Lirong

Strategic Study of CAE 2005, Volume 7, Issue 4, Pages 36-41

Abstract:

In this paper, the automatic meteorological recorders of time —sequence are transformed into structure information on the basis that time doesn't own dimension of matter. The results show that the irregular information of automatic meteorological recorders may be used in careful forecasting of rain storm, which will provide a technique for evolutional irregular information over a wide range. So, the meteorology should be of evolutional science, or in other words, taking it as a branch of the inertia system of I. Newton is open to question.
