single point a chroma amplitude 单点色度幅度
half-amplitude point 半幅度点
The computation simulation results show that in confocal optic system this mask can change the point amplitude response. It can improve the resolution, while increase the image contrast.
模拟计算结果表明，在共焦系统中利用该掩模可以改变系统的点振幅响应，从而提高分辨率，并增强图像的反衬度。
If you take a spring, it is true that the period of oscillation is independent of the amplitude but only up to a point.
如果用弹簧，周期的确和，振幅无关，但也只是点到为止。
From this point, M-ary Quadrature Amplitude modulation (MQAM), MultiCarrier modulation (MCM) and adaptive modulation techniques are good candidates in next generation mobile radio system.
从这一点出发，多元正交幅度调制(MQAM)、多载波调制(MCM)及自适应调制技术成为下一代移动无线系统中最有竞争力的几种候选技术。
