我将要证明，一个只有z分量的向量场的通量,等于一个三重积分，其中被积表达式为。
I'm going to prove that the flux of a vector field that has only a z component is actually equal to the triple integral of, RzdV well, the divergence of this is just R sub z dV.
使用单引号或三重引号的字符串前面可以加一个字母“r ”以表示Python不应该解释规则表达式特殊字符。
Both single-quoted or triple-quoted strings may be preceded by the letter "r" to indicate that regular expression special characters should not be interpreted by Python. For example.
因为在scala里if语句是一个表达式，所以就不需要c类型子语言的三重条件表达式了。
Because if statements are expressions in Scala, there is no need for the special-case ternary conditional expressions that exist in C-derived languages.
在一个字符串上调用。r会把它变成一个正则表达式；我们是用了原始(三重引号)字符串来避免诸多双重转义的反斜杠。
Calling.r on a string turns it into a regular expression; we use raw (triple-quoted) strings here to avoid having to double-escape backslashes.
