This paper presents operation principle of gear dynamic engagement system and points out shifting conditions according to geometry, kinematics and kinetics theories. - 为了适应市场经济条件下社会治安动态管理的需要,我们必须调整警务战略的构成要素,并使之形成衔接互动、高效运转的工作机制,为此就必须推行公安警务机制改革,努力构建贴近实战的警务管理模式。
To meet the needs of dynamic administration and modern metropolitan public security in the market economy,it is essential to adjust the components of policing strategies,and establish the highly efficiently operated and interlocked functional mechanism.Therefore,we must promote reform of police services and strive to construct the policing administration model close to the field work.
