Having the antenna at the bottom means less radio frequency waves are flooding the sensors.
将天线安置在底部意味着传感器会探测到最少的电磁波。
That night, the researchers measured one particular sleep phenomenon: the brief bursts of high-frequency waves known as “sleep spindles.”
那天晚上,研究人员研究了一种特殊的睡眠现象:出现的短暂高频率脑电波,即众所周知的“睡眠纺锤波”。
Scientists are mostly stumped as to how the radio frequency waves emitted by cellphones, which lack the punch to break chemical bonds or disrupt DNA, might cause cancer.
科学家们主要搞不懂的是,手机所释放的无线电波,连打断化学键或扰乱dna的冲击力都没有,又怎么可能导致癌症呢?
The catch is that because low-frequency waves can travel great distances, when they do bounce off cavities or objects underground, they often end up far from the detection equipment at the surface.
捕捉过程是这样的,因为低频波可以传输到更远的距离,当它们遇到地下的空穴或其他物体反射回来的时候,已经距地面的接收装置很远了。
The detection of Pre-P wave was affected by the heart rate, respiratory, artefact and low frequency waves.
前波的表达受心率、呼吸、伪差及低频波等因素干扰。
Cellphones send signals to nearby towers via radio frequency waves, a form of energy similar to FM radio waves and microwaves.
手机经过射频电波(一种与调频电波和微波类似的能量方式),将信号发送至左近的信号塔。
An optical fiber is actually a tiny wave guide which supports optical frequency waves using the principles of total internal reflection at the boundaries of the fiber.
光纤维实际上就是一根纤细的波导管它应用全内反射原理在自身范围内承载光波。
