摘要
在物理试验中包括许多物理过程,为了掌握这些物理过程,需要对这些过程进行诊断。安排了各种各样的测试项目,实施物理测量都是通过物理试验产生的各种脉冲辐射场信号进行测量。这些信号是瞬变的非周期的单次脉冲信号,有的频率很高。这些单瞬变的脉冲波形多采用高频同轴电缆传输,传输到终端记录测量,因此做好传输信号在电缆中的传输,对每次物理试验过程中都十分重要。
Physical experiments include many physics processes. In order to mastering these processes, we need to diagnose and measure them. Many signals such as signals of impulse radiation and magnetic field from physical experiments can be measured through various physical measure methods. These signals are instantaneous and nonperiodic, some of them have very high frequency. The instantaneous impulse wave which is transmitted by high frequency coaxial-cable to terminal can be noted and measured. It's important for every physical experiment to transmit the signals through coaxial-cable.
