In Kontexten kann "presentation" verschiedenen Bedeutungen haben. Hier bedeut der Satz "在演讲（介绍/致辞）的末尾 oder 在演讲（介绍/致辞）结束时"

should be "谢谢您的关注"

at the end od presentation, we speak"Thank you for your attention!" for the end. but in chinese we say" Thanks for your time""感謝諸位的時間".Chinese is a polite people.(It means that that we did NOT pointn out that you are pay attend to my speach,so we only say tks for your time.FYR)

I would just say: 谢谢. Because in Chinese there is no expression like " thanks for your attention". It's a very English. Normally at the end of a presentation we would just say something like" thanks for coming or something like" this is it. thanks a lot"

感谢您的关注
