主动约束层阻尼 Active Constrained Layer Damping
主动约束层阻尼板结构 plate with active constrained layer damping
主动环形闭合约束 active loop closure constraint
而这个主动约束力的大小，则是通过分析力学中拉格朗日方程推导出来的。
And we can get the constraint force by a new form of Lagrange equation.
利用主动控制和约束层阻尼处理优势互补，构成既有主动控制高效智能、又有约束层阻尼处理稳定可靠特点的主动约束层阻尼振动控制系统。
By using the merit of active vibration control and constrained layer damping treatment, active constrained layer damping treatment is not only efficient and intelligent but also stable and reliable.
需具备主动进取的工作态度，并具有自我约束能力和积极性，要为下属树立良好的工作榜样。
Acquire a positive working attitude. Be self-disciplined and self-motivated; set a good working example for all sub-ordinates.
