三张图不同地点取样。图一是废气源样品，出现双头峰，属于正常现象么？积分一起积分么？图二车间取样，峰也不规则。图三厂区取样还算正常，出现图一图二不规则拖尾峰怎么处理？求大神指教！！[img=,690,357]https://ng1.17img.cn/bbsfiles/images/2019/07/201907081529267645_6677_3953496_3.jpg!w690x357.jpg[/img][img=,690,357]https://ng1.17img.cn/bbsfiles/images/2019/07/201907081529267645_6677_3953496_3.jpg!w690x357.jpg[/img][img=,690,517]https://ng1.17img.cn/bbsfiles/images/2019/07/201907081529354672_4972_3953496_3.jpg!w690x517.jpg[/img]
