heartbeat rate meaning in English
心搏率
Examples
- The new technology of non - contact life - parameter detection is relative to that of the normal contact one , which uses microwave beams to illuminate the human subject , whose reflected wave will be modulated by the surface movement resulting from the physical activity . by this way , some parameters of the reflected wave , such as frequency and phase will be changed . if these changes can be detected , the life parameters such as respiration rate and heartbeat rate will be extracted from those changes
非接触生命参数检测是相对于常规的接触式检测而言的一种新技术，它利用微波束照射人体，其回波信号被人体生命活动引起的体表微动所调制，使得回波信号的某些参数(如频率、相位)发生改变，检测到这些变化就能从中提取出人体的生命参数(如呼吸或心跳) 。
