很有用的Html 显示特殊符号
1. 显示立方米
m<sup>3</sup>/s
同理显示平方米即是
m<sup>2</sup>/s
2.其他的特殊符号 说明一下这是我从网上找的，搜了很长时间才找到，希望与大家分享一下
一个字符实体(Character Entity)分成三部分：第一部分是一个&符号，英文叫ampersand；第二部分是实体(Entity)名字或者是#加上实体(Entity)编号；第三部分是一个分号。
用实体(Entity)名字的好处是比较好理解，一看lt，大概就猜出是less than的意思，但是其劣势在于并不是所有的浏览器都支持最新的Entity名字。而实体(Entity)编号，各种浏览器都能处理。
