一、前言: 随着工农业生产和科学技术的发展,脉冲技术已广泛应用于雷达、电视、遥控、电子计算机等各种电子设备。近几十年来,在原子能工业,诸如等离子物理、加速器技术等方面也得到广泛应用。现代脉冲系统的发展是与利用电缆传输脉冲相联系的。例如用同轴电缆传输高压瞬时大电流脉冲能量进行受控热核聚变反应的研究,在核武器试验中很多瞬态现象都是依靠同轴电缆把信号传输到示波器中进行观察的。又如在高能质子加速器中有用同轴电缆作脉冲形成网络的或将脉冲形成网络发出的能量(矩形脉冲)传输到能使质子束很快引出和加速的磁铁上去。即作从闸流管→冲击磁铁→负载用的脉冲传输电缆。为满足脉冲讯号的传输,对作为传输线的同轴电缆要求
I. Preface: With the development of industrial and agricultural production and science and technology, pulse technology has been widely used in various electronic equipment such as radar, television, remote control and electronic computer. In recent decades, it has also been widely used in the atomic energy industry, such as plasma physics and accelerator technology. The development of modern pulse systems is linked to the use of cables to transmit pulses. For example, coaxial cable transmission of high-voltage instantaneous high-current pulse energy for controlled thermonuclear fusion reaction research, in the nuclear test many transient phenomena are relying on coaxial cable to transmit the signal to the oscilloscope for observation. Another example is the use of high-energy proton accelerators coaxial cable to form a network of pulses or pulsed network formation of the energy (rectangular pulse) is transmitted to the proton beam can quickly lead and accelerate the magnet up. That is used for the thyratron → impact magnet → pulse load transmission cable. To meet the pulse signal transmission, coaxial cable as a transmission line requirements
