His I. Q is 75. Well, we're all different, Mr. Hancock.

Let me give you, I'm going to create, q a polar point, I'm going to call it q, and we'll give it some random values.
让我给大家讲解下，我要去创建，一个极坐标点，然后我会去命名它为，然后我给它赋一些随机的值，好，现在我想知道。
-
q1 The heat input is just q1, Q and we'll define that as capital Q.
输入的热是，我们把它定义为大写的。
-
All right, so that's just solving out the algebra, so we're saying what q solves, a - c over 2b - q2 over 2 = 0.
没错,只需要解出当,/2b-q2/2=0,时q2的值即可
-
u=q+w We have a relationship between them.
它们之间有关系Δ
-
w Now, we have u, q and w.
现在我们有u，q和。
-
All right, q has to be just the opposite of this because we've already figured out that there's no change in u.
好，q一定与它,相差一个符号，因为我们已经,指出U是不变的。
-
du We can talk about du for the system well, w that's q plus w.
我们可以讨论它的，等于q加。
-
U And then if we can also determine delta u, then we know this, we know delta u is q plus w w, then we can determine work as well, right?
然后，如果我们也能定出△,然后我们知道这个,我们知道△U等于q加？
-
All right, what we've already got that q is zero.
好，现在我们已经知道了q是零。
-
So we've already seen that q is zero.
我们已经知道q等于零。
