The existence of bounded states and limit sets are concerned in order to explain chaos and turbulence phenomena in quantum field theory. Bifurcation and two critical speeds are discussed.
有界状态和极限集的存在性解释了量子场理论中混沌现象与湍流现象的内涵，并讨论了分歧现象与临界速度。

In this paper, based on -, the uniform convergence of the Kth order weak bounded variation functions on the sequence Spaces were investigated. Some equivalent conditions were also obtained.
Using concepts of invariable set and isolated cube, we obtained existence for bifurcate points of bounded solutions of second order ordinary differential systems including a parameter.
