In the newer type coaxialsystem, the signals transmitted are much higher in frequency and amplifiers are required every four miles.
在较新式的同轴电缆系统中，传输信号的频率高得多，所要只每隔四英里装一个放大器。

Using this system, coaxial degree of the helicopter transmission can be measured fast and accurately.
现场试用证明系统可以及时、准确地测量出直升机传动系统的同轴度。
