根据程度不同，信息所显示的符号也不同(一个蓝色圆圈，一个黄色三角形，或者中间带一横杠的红色圆圈)。
Depending on the severity, a different symbol is shown for the message (a blue circle, a yellow triangle, or a red circle with a cross inside).
比如说，我有个朋友的母亲不管什么人什么事她都要横插一杠。
For instance, a friend of mine has a mother who always interjects her opinions about everything to everyone.
请注意这里的小横杠，说明这不是一个准确的微分。
And this little slash here means an in inexact differential.
