In this paper, it is pointed out that the accuracy of measurement must be considered for the discussion about the restitution time of damped vibration, and it is in the "critical state of weakly damped vibration" defined by this paper, not the critical damping state, that the restitution time is the shortest.

1 问题的提出和回复时间的定义众所周知，阻尼振动按阻尼的大小可分为弱阻尼、临界阻尼和过阻尼三种情形。几乎所有的教材均指出，临界阻尼运动是物体刚能不做周期性运动而又最快地回到平衡位置的运动，也即其回复时间最短。

In the video segmentation method based on DEMD, the intrinsic mode function with the lowest frequency is discarded and a simple and effective motion compensation method is adopted. As a result, the video segmentation method is no longer sensitive to abrupt change of luminance, object motion in shots, motion and zoom in/out of cameras, so that the precision of detecting shot boundaries is improved.

基于DEMD的视频分割方法除去视频帧中反映图像内光照分布与能量的最低频率固有模态函数(intrinsic mode function，IMF)分量，并选择一种简单有效的运动补偿方法，解决了传统基于直方图方法对光照突变、镜头内物体运动和镜头运动及拉伸的敏感问题，减少了镜头边界识别的误检率，在保证召回率不受影响的前提下提高了视频分割的精确度。

Second order incident boundary condition on fixed incident boundary is derived for numerical simulations, based on the cnoidal or sinusoidal motions of wave maker paddle, which shows that the prediction with second order incident boundary condition is more accurate than the prediction with first order incident boundary condition. 2 The analytical solution for higher-order Boussinesq equations is derived and its applicable range is discussed. 3 A 2-D fully non-linear numerical model using boundary element method is developed to obtain wave forces acting on rectangular obstacle. 4 The three-dimensional fully non-linear waves are studied in a numerical wave tank using finite element method.The studies on the coupled numerical model combined Boussinesq equations with Laplace equation are following.

Well, the law of inertia says that something in motion will tend to stay in motion, and what's more, to move in a straight line.

惯性定律说，任何处于运动的物体会继续保持运动，而且，会在一条直线上运动。

D: Well the law of inertia says that something in motion will tend to stay in motion, and what's more, to move in a straight line.

惯性原则就是：运动中的物体要保持运动的状态，同时保持直线运动（惯性守则好像不是这么说的吧，请参看楼上的）。
