只提供摘要形式。在原子气体的电离过程中会产生高次谐波，因此电离的概率、未电离原子的数量和相位匹配效应会对谐波的产生施加一个自然的时间包络。我们做了一些模拟，显示了谐波强度的最大值、最小值和平均值作为角频率失谐乘以谐波脉冲长度的函数。从最大信号的包络中可以提取出高次谐波脉冲持续时间。
Summary form only given. High harmonics are generated during the ionization of an atomic gas and therefore the probability of ionization, the number of unionized atoms, and the phase matching effects will impose a natural temporal envelope on the harmonic generation. We made some simulations which showed the maximal, minimal, and averaged possible values of the intensity of the harmonic as a function of the angular frequency detuning multiplied by the length of the harmonic pulse. From the envelope of the maximum signal we can extract the high harmonic pulse duration.
