Email中的CC和BCC的含义

Email中经常用会用到抄送（CC）和密送（BCC），具体的英文含义是什么一直不清楚，今天在听ESLPod时里面对CC和BCC的含义进行了介绍，顺便用Google翻译查了一下具体的含义：

• CC:Carbon Copy,根据Google翻译的解释：used as an indication that a duplicate has been or should be sent to another person
• BCC:Blind Carbon Copy,根据Google翻译的解释：a copy of an e-mail sent to someone whose name and address isn’t visible to other recipients.
