1·After being treated, the wastewater looks transparent. Both BOD and COD values are lowered for 60%. The suspension removed rate to 91%, and chrominance for 77%.
经该法处理的酿酒废水外观清晰透明，BOD, COD值均降低6 0 %以上，悬浮质去除率达91%，色度去除率为77%。
2·Applying the theory of multi dimensional digital signal processing, this paper analyses the 2-dimensional interleaving structure of luminance and chrominance spectrum for the PAL signal.
运用多维数字信号处理理论，分析了PAL信号亮度和色度频谱的二维交错结构。
3·This paper presents a "waveform display method" for checking the colour TV Chrominance Delay Line in the factory, and introduces a simple, practical and self-made test-signal generator.
本文提出一种适用于工厂检测彩色电视色度延迟线的“波形方法”，并介绍了一种自制的简易实用的测试信号源。
