关于一些名词的翻译问题

3

比如Vector，Tuple等表示数据结构的名词，翻译成向量、元组的话不如直接使用英文直观。比如“向量”容易和数学上向量的概念混淆。 翻了一下《C++ Primer》和《Thinking in Java》这两本比较经典的入门书籍，里面关于Vector、Map、Set等数据结构，大都不进行翻译。 Slice 是否翻译为“切片”更好？ 我之前接触的编程语言里只有Python有类似的功能，而这功能在Python的翻译一般翻译为“切片”。不知道其他语言怎样翻译。 Trait 这个好像是Rust特有的关键字？翻译成“特性”的话，如果我之前没了解过Rust的Trait，光看“特性”的话有点难对上这个关键字。 参考： [1] [C++ Primer 4th edition](http://vdisk.weibo.com/s/Ab9vgtTedDkQ) [2] [Thinking in Java 3rd edition](http://vdisk.weibo.com/s/Ab9vgtTedDkK) [3] [Python教程 - 廖雪峰的翻译](http://www.liaoxuefeng.com/wiki/001374738125095c955c1e6d8bb493182103fac9270762a000)
