截断函数 meaning in English
truncated function
Examples
- Numerical examples illustrated the spatiotemporal properties such as spectrum redshifting , narrowing and pulse distortion , etc . it is stressed that the " antibeam " behavior of ultrashort pulsed beams can be avoided , if a suitable truncation function is introduced to the initial pulse spectrum
数值计算例说明了在色散介质中会出现谱红移、变窄、及脉冲形变等传输效应，而且对初始光谱引入截断函数可以避免“非光束”行为。
