When parameters satisfy some assumptions, Rossler system is a chaotic dynamical system. In order to discuss the dynamical character of Rossler system and use delayed feedback control chaos, in the first, we discuss the stability of the steady states of Rossler system with delayed feedback. When the engenvalues of the linear part are pure imaginary numbers, we obtain the corresponding delay value. The stability of the steady state is lost when the delay passes through the critical value, and simultaneity chaos may vanish, as well as there will be a family periodic solutions bifurcate from the steady states.

在几个参数满足一定的假设条件下，Rossler系统是一个具有混沌特性的动力系统，为了研究该系统的动力学性质并利用时滞实现混沌控制，本文首先对具有时滞的Rossler系统的平衡点进行稳定性分析，当系统的线性部分对应的特征值为纯虚根时，算出相应的时滞τ，得到了平衡点的稳定性会在时滞τ取某些值时发生翻转，同时系统的混沌特性也会出现变化，并且在平衡点处系统经历Hopf分支。

这是一个由内而外、由本质到现象不断循环的立体社会发展动力系统，其中每个环节都是社会发展的一个层面的动力，但都不是单独的最终动力。

Robertson, the former CEO of Rolls-Royce, told journos that the two vehicles would use diffent hybrid systems. The luxury sedan 7-series would make use of a mild hybrid, allowing the engine to be shut down when coasting or braking. Accessories would still run with the engine shut down, making use of an electric motor.

Robertson对记者表示这两款新车将使用不同的混合动力系统。7系车将采用弱混合动力系统，当车辆在低速巡航或制动时可以关闭引擎，由于配备了电动机，可以在引擎关闭时车内的其他设备可以继续运转。

General Dynamics will now work closely with the Department of National Defence in defining the scope of the LAV III upgrades. At the heart of the upgrade program is a high-capacity driveline and suspension that significantly increases the vehicle's payload. Increased payload will allow the vehicle the ability to deliver even better protection for Canadian soldiers.

通用动力现在与国防部在定义LAV III轻型装甲车升级范围上将进行紧密合作，升级项目的核心是可以大幅提高有效载荷的高容量动力系统和悬挂系统，增加的载荷可以更好的为士兵提供保护。

In the future, some issues need to be investigated further, which include: establish and study the low-dimensional dynamical system of turbulent jet, with the POD bases, the control of turbulent jet based on the low-dimensional dynamical system of turbulent jet, investigate the physics mechanism of intermittence shed-off of the vortex ring in turbulent jets in crossflow.
