The original video is spitted into a series of frame groups,for each frame in the group,the points of contour shape are described by MPEG-7,and taking advantage of hash function to calculate the keys between those points in the 1D- DFT transform domain and the watermark signals.

在该算法中，原始视频数据被分割成等帧数的视频组，利用MPEG-7的轮廓编码计算每个视频帧的主要物体轮廓坐标点集合；接着通过傅立叶变换得到该帧轮廓点形状不变量，利用哈希的方法计算水印信号并将这些不变量的有效值作为密钥之一；再对整个视频组的轮廓点进行傅立叶变换，得到其时间轴上的有效不变域，将水印信号嵌入在这个不变域的中频部分以确保了水印的鲁棒性。

Because shockwaves might disturb regular airflow at fans with a high tip-speed (axial speed at the tip of a fan blade), fans are developed to keep to tip-speed as low as possible, not more than two or three times the local axial velocity.

因为冲击波可能会以高度的扇叶速扰乱来自风扇的常规气流，风扇被改进成保持扇叶速尽可能的低，至多2或3倍于开始的轴向速度。

Phase-lagged cyclic boundary condition is implemented by a novel method in conjunction with the developed sliding interface technique to accurately simulate the arbitrary pitch ratio rotor/stator interaction without any modifications of the physics of the problem. It's for the first time to compose the computational area into one structured grids including both rotor/stator of centrifugal or axial turbomachinery with arbitrary pitch ratio. This method can eliminate the iteration of boundary conditions on the sliding interface and calculate the unsteady flow within rotor and stator simultaneously.
