摘要
本文试用泛系观探讨流体在旋转与辐合运动中的暴转(blow-uP)与暴转后的特征。发现运动流体具有逆向转化性,逆时针旋转可暴转为顺时针旋转,反之亦然;辐合可暴转为辐散,但辐散会连续地消亡。预测应正视这种机理,天气预测不能只作为传统的Cauchy问题,传统的预报模式有待置疑。
From the pansystems view of prodiction, the paper investigates the blow-up and post-blow-up of fluid in rotation and convergence. The results show that the motion includes certain characteristics of reverse transformation, the counter clockwise rotatino can be developed into clockwise, vice versa , and 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 con-sidered only as a traditional Canchy problem. The traditional forecast models should be rediscussed questioningly.
