I m : information content of a message
信息量
（1）
The information content of a message is therefore a measure of its scarcity. Hence, with a message that is a certainty, it carries no information and has an information content of zero. A most important aspect of the theory is that it does not measure the meaning or semantics of the message. scarcity ：缺乏，不足；稀少，罕见，难得 semantics ：语义学 因而消息的信息量是其缺失性的一种度量。由此，一个确 知消息，是不含任何信息的，它的信息量为0。信息量的一 个重要方面是它不检测消息的意义或语义。
