随着现代科学技术的发展,对于一些变化速度极高而延续时间极短的过程的研究日趋重要。例如爆炸过程的研究、高速旋转机件的震动、短暂电磁过渡过程的分析等均需要有能将这些过程记录下来的高度完善的仪器与测量技术。显然,最完善的记录应包括现象随时间而 With the development of modern science and technology, the research on some processes with extremely high changes and short durations has become increasingly important. For example, the study of the explosion process, the vibration of high-speed rotating parts, the analysis of transient electromagnetic transitions and the like require highly sophisticated instrumentation and measurement techniques that can document these processes. Obviously, the most complete record should include the phenomenon over time
