But under the condition of large energy and long pulse the plasma arc may fill the flashlamp bore. 但在大能量长脉冲放电情况下，大口径氙灯的等离子体也可以充满内径。
But ordinary xenon lamps flame unstably, then one or several data points can be sampled during a single flash.Tens of flashes are needed to achieve a whole test. 但一般频闪氙灯的光强不恒定，单次闪光一般只能采集一到几个测试数据，故一次测试需要至少闪光几十次。
