干扰检测 disturbance detection
interference detection
- 回到实验室,研究人员从酒中脱去酒精。这么做是为了防止酒精干扰检测。
Back at their lab, the researchers stripped the alcohol out of the wine. They did that to preent ethanol from interfering with their lab tests. - 方法:强调在心电信号检测过程中,很容易受到噪声(干扰)的影响,如随机噪声、工频干扰、检测系统的内部噪声等。
Methods Influential factors in ECG signal detection were analyzed including random noise, power frequency interference, inner noise from detection system, etc. - 结果表明,2M多功能全息平台比JQS-B型全息平台的稳定性好;对于外来的干扰,检测时产生的条纹漂移量不超过1/8条,说明工作台隔震效果较好;对于人为引入的干扰,条纹急速晃动后能在几秒钟稳定下来,则表明平台消震性能良好。
The results showed: The stability of 2M holographic platform that of JQS-B holographic platform; The property of tremble isolation was satisfied because the excursion was under 1/8 stripe for the outside disturb, The property of tremble elimination was also satisfied because the stripe couls be rapidly stabilified after the artificial stripe tremble.
