The Pansystems View of Prediction and Blow-Up of Fluid

From the pansystems view of prediction,the paper investigates the blow-up andpost blow-up of fluid in rotation and convergence.The results show that the motion includes certain characteristics of reverse transformation,the counter clockwise rotation can be developed into clockwise,and vice versa;the convergence can be changed into divergence and post blow-up,but the divergence will die out continuously.The real forecasting must look this mechanism in the face.Geneally speaking,the forecasting of evolution for fluid can't be considered only as a traditional Cauchy problem.The traditional forecast models should be rediscussed questioningly.
