In this study, we investigate the effect of post-annealing on magnetization damping in sputtering deposited NiFe thin films. The film thickness is ranged from 10 nm to 100 nm. Thin films were deposited at room temperature and a subsequent post-annealing was performed in vacuum better than 10-6 torr from room temperature to 700 0C for 30 minutes.

中文摘要本研究中，我们使用改变后退火效应来观察溅镀制程镍铁薄膜(Ni84Fe16)系列的磁性阻尼行为，溅镀薄膜厚度范围为10 nm ~ 100 nm，而镍铁薄膜后退火过程在真空度约10-7 torr中进行，达到标的温度(范围由室温至700 ℃)后定温30分钟，自然冷却取出。

The differential equations of motion and the state space model of the single inverted pendulum nonconservative damping system are deduced by using the second kind Lagrange equation.

In traditional vehicle model, spring and damper are usually parallelly arranged.

传统铁道客车模型一般是弹簧、阻尼器并联的形式。

Even though the pilot can correct easily for the phugoid mode it would become extremely fatiguing if the damping were too low.

但若阻尼太小飞行员要一直去矫正会造成飞行员的疲劳

For the properties of high nonlinear, low frequency, low stiffness and small damp of pneumatically driven systems, it is difficult to realize high precision position servo control.

由于气压驱动系统本身具有强非线性、固有频率低、刚度低和阻尼小等特点，实现高精度的位置伺服控制比较困难。
