random turbulence

This paper deals with the problems of the optimal control of the airplane landing in presence of atmospheric turbulence with application of the theory and me-thods of random optimal control.

论述了应用随机最优控制理论的基本原理和方法，解决飞机在大气紊流中着陆的控制问题。

When the chaotic quasi attractor just appears, the chaotic time sequence shows a random intersperse between laminar and turbulence phases.

在混沌类吸引子刚刚出现时，混沌时间序列呈现层流相与湍流相的无规交替。

Consequently, the turbulence is composed of the deterministic chaos and the random noise, where the motion of large eddies in the turbulence follows the rule of chaotic motion and the random noise arises from the random motion of small eddies in the turbulence.

由此可见，湍流可分解为确定性的混沌和随机噪声两部分，其中湍流中大涡的运动遵循混沌运动规律，而湍流中小涡的随机运动构成了湍流的随机噪声。
