The key factors of the Relayed frequency shift jamming to it's quality are it's frequency shift amount and the time delay between the jamming pulse and the jammed signal. 决定转发移频脉冲干扰品质的是其移频量和与信号脉冲的相对延迟时间。
The nonlinear relationship between roll crown of CVC rolls and their shift amount is first deduced. The concept of crown limit is first given in the paper. 首次推导出了CVC轧辊凸度与轧辊轴向移动量之间的非线性关系,提出了凸度极值的概念。
The obvious merit of mean shift is lesser amount of calculation, simple and easy to realize, so it can meet the need of real-time tracking. But it fails in tracking small and fast moving targets and in recovering a track after a total occlusion. 它显著的优点是算法计算量小,简单易实现,很适合于实时跟踪场合;但是跟踪小目标和快速移动目标时常常失败,而且在全部遮挡情况下不能自我恢复跟踪。
GaAs / AlGaAs quantum dots were made by Electron Beam Lithography ( EBL ) and Reactive Ion Etching ( RIE ) on GaAs / AlGaAs quantum well wafers. Their photoluminescence shows blue shift, the amount of blue shift increases with the decrease of quantum dot size. 采用电子束曝光和反应离子刻蚀的工艺,将GaAs/AlGaAs量子阱外延材料制成量子点阵,其光荧光谱显示出蓝移,并且蓝移量随着量子点直径尺寸的减少而增大。
Firstly, considering the shift and distortion frames amount images, we carry on motion estimation before gray image restoration. 首先考虑多帧图像之间会存在运动位移或形变,在进行灰度图像盲复原前先对图像进行运动估计。
