Generation 9/11 refers to the generation of people who were enrolled in high school or university on September 11, 2001.

“9·11一代”是指在2001年9月11日进入高中或大学的那一代人。

除了generation 9/11，9/11 generation也可以指代这一代人。

For Example：

After the deadliest attack on American soil in the history of the republic, the generation that previously seemed directionless and without a fitting title now had one — 9/11 Generation. "After Sept. 11, there was a definite change," said Luke Punzenberger, president of Marquette University Student Government. "It's something I can't put my finger on. You walk down campus and it just feels different."

在共和国历史上最致命的袭击发生在美国这片土地上后，此前被视为没有方向，也没有合适称谓的一代人如今有了称号——“9·11一代”。马凯特大学学生会长卢克·潘振博格称：“9·11事件发生后，发生了明显的变化。那是些说不清道不明的东西，走在大学校园里，就是能感觉到不一样了。”
