您要查找的是不是：
- Otherwise, wide pulse and slow falling edge can cause the errors of surface recombination velocities and bulk lifetime extracted from the photoconductive decay curve. 否则脉冲光过长的脉宽和下降沿将对光电导衰减曲线中进一步分离出的表面复合速度和少子体寿命结果造成误差。
- For the samples less influenced by the surface conditions (for example, shorter bulk lifetime or lower surface recombination velocities), the requirement of pulse width can be not strict. 若样品受表面状况影响较小时（如体寿命较低或表面复合速度低时），则可对两种理想脉冲光源的要求适当放宽。
