line notation

基本解释

Then the flux of F across a curve C is, by definition, a line integral but I will use notation F dot n ds.
根据定义，F通过平面曲线C上的通量是一个线积分,用符号F•n，ds表示。
UML 2 has addressed this problem by removing the "in-line" guard and adding a notation element called a Combined Fragment.
UML 2 已经通过去掉“in-line”约束，增加一个叫做组合碎片的符号元件，解决了这一个问题。
You can use the $ notation for the last line to specify to the end of the file and double greater-than symbols (>>) after the w to indicate that you want to append to rather than overwrite the file.
对于最后一行，可以使用 $ 表示文件的末尾。可以在 w 后面使用两个大于号（>>）表示希望把内容附加到文件中而不是覆盖文件。

So you have what are called escape characters like backslash N that is the shorthand notation of telling the computer put a new line character here.
幸亏我们有一些类似反斜杠n的转义字符,这只是一种简化方式,用来告知电脑要在这新添一行。
