The pulseenvelope we obtained is a hyperbolic secant function of time.
所得脉冲包络为时间的双曲正割函数。

And a theoretical model is established to expound the variation of pulse duration and the modulation on the pulseenvelope similar to the diffraction characteristics in spatial domain.
通过与光束的空间传输特性类比解析了光栏宽度变化引起的脉宽变化以及脉冲轮廓出现时间衍射调制现象；
