1. Within their compact bodies these minute satellites are able to house sensors and communications receivers/transmitters that enable operators to study Earth from space, as well as space around Earth. 这些微型卫星体积小巧，能够容纳传感器和通信接收器、发射机，使操作人员能够从太空中研究地球以及地球周围的空间。
2. The transmitters will send a signal automatically to a local base station. 发射台会自动将信号发送到地方基站。
3. The above photographs are of brain transmitters. 上面是大脑信号传输器的照片。
4. Transmitters emit waves of a certain frequency in the direction of the target. 发射器朝目标方向发射一定频率的无线电波。
5. But some too-powerful radio transmitters encroached on the ESA's frequency. 不过有些过于强大的无线电发射台侵犯了欧洲航天局的频率。
