A But I tend to use P Q R for sentences and A for A, now that I have explained it, that should be smaller case.
但是我喜欢用P，Q，R来代表句子，A就代表，我已经解释了，应该是小写的。
Q comes between P and R in the English alphabet.
英语字母表中，Q在P和R之间。
And for that to possibly happen, well, we need certainly some relations between p, Q and r.
要使得这个成立，当然需要一些p,Q,R之间的关系。
Let's say that my vector field has components p, Q and r.
假定我的向量场。
We want to know whether a given vector field with components P, Q and R can be written as f sub x, f sub y and f sub z for a same function f.
要看向量场,能否写成，其中f是同一个函数。
