1、卷边是什么意思

1、为增加工件边缘的刚性和强度将工件的边缘卷曲叫卷边。

2、边缘加工是指在钢结构制造中，经过剪切或气割过的钢板边缘，其内部结构会发生硬化和变态。为了保证桥梁或重型吊车梁等重型构件的质量，需要对边缘进行加工，其刨切量不应小于2.0mm。

3、此外，为了保证焊缝质量，考虑到装配的准确性，要将钢板边缘刨成或铲成坡口，往往还要将边缘刨直或铣平。

2、Off the cuff 难道是让你卷起袖口？你到底要干嘛？

周末和公司同事一起聚餐，开吃前总得先听邻居嘚啵嘚啵才行[小鼓掌]~于是大家就起哄让老外副总讲两句，猛得被点名儿，一看他就是没准备好，于是就红着脸说道:" I'm not very good at making off-the-cuff speeches..." 会计小刘又不明白了，问我说:"你说让他两句，他说什么挽袖口儿啊~"[抠鼻]

其实这里老外是用了一句地道的口语表达，他说的意思是"我不太擅长即兴演讲"。得嘞，那今天就来跟大家说说这个"off the cuff"的用法吧！"cuff"大家都知道是"袖口、裤脚外卷边"的意思，连在一起就是"即席、即兴、没准备、很随意"的意思啦。而这句短语的起源据说来自一些演讲者没有事先准备好演讲稿，于是他们就只能临阵磨枪，把演讲的要点写在衬衣袖口上应付一下了。

off the cuff

na. 即席的；即兴的；未经准备的；随意

【En】If you speak off the cuff, you say something without having prepared or thought about your words first. 如果你即兴发言，指的是你会在没有事先准备或考虑的情况下说一些话。An off-the-cuff remark is made without being prepared or thought about in advance.即兴评论是在事先没有准备或思考的情况下说的。An off-the-cuff remark, reply etc is one that you make without thinking about it first.即兴评论、回答等是你没有事先考虑就做出来的。

得嘞，还是老规矩，先来听几句跟这个短语有关的例句吧，把耳朵磨灵光喽，学起英语来就快多啦！[听歌]
