事情是这样的，我跑梯度，设置初始浓度那里，一开始没留意初始浓度是0.5%跟我梯度初始30%不一致，发现峰跑的很好，改回30%之后峰就变宽了，怎么解决啊[img=,690,920]https://ng1.17img.cn/bbsfiles/images/2020/09/202009221101482012_8458_4245381_3.png[/img][img=,690,920]https://ng1.17img.cn/bbsfiles/images/2020/09/202009221102096323_215_4245381_3.png[/img][img=,690,920]https://ng1.17img.cn/bbsfiles/images/2020/09/202009221102365410_471_4245381_3.png[/img][img=,690,920]https://ng1.17img.cn/bbsfiles/images/2020/09/202009221102462275_2438_4245381_3.png[/img]
