目前为止科学家接收到约60个快速电波爆发,仅有两次重复电波。
So far, scientists have detected about 60 single fast radio bursts and two that repeat.
所有这些都与传输的无线电波有关,而我们无法直接控制它们在发射器和接收器之间的传输路径。
All of this relates to radio waves being transmitted and we cannot have direct control over the paths they take between transmitter and receiver.
航天器遇到电波时,传感器会记录电场和磁场频率的变化。
As the spacecraft encounter a wave, sensors record the changes in the frequency of the electric and magnetic fields.
