Those two equal signs are saying, is this thing equal to, in value, the thing on the other side?
这两个等号意思是，左边的对象，在值上是不是和另外一边的相等？
-
Depending on how far the planet is from the Sun and where it's located, you will get the left-hand side.
取决于行星到太阳的距离以及行星的位置,你就能列出等号左边的式子
-
It turns out not, but it does evince the fact that we have some basic syntax like mathematics and equal signs and whatnot with which we can now start using for more useful purposes.
结果不是那样的，但这的确有个事实,我们有些基本的运算法则和等号和,其他一些东西，用来为我们一些,更多有用的目的而服务的。
-
I've gone from 1 equilibrium state to another equilibrium state and the equal sign means you go from this state to that state.
从一个平衡态,过渡到了另一个平衡态,等号表示,从这个态到了那个态。
-
Having already chosen to use equal as an assignment, I need something else to do comparison.
既然等号是,用来赋值的，我需要用一些东西来做比较。
-
Take these two equations, put an equal sign between them, replace this PR throughout with X, I'm going to have one equation and one unknown and that even the math phobics in the audience did in high school.
在这两个方程中间加个等号,将这里的Pr换成X,就会得到一个等式和一个未知数,剩下的问题,大家高中的时候就该回做了吧
-
And one of the things neophytes trip over early on is that we'll soon see there's not only an equal sign operator, there's equals equals.
这样我们还要引入了一个新的操作符,我们将看到这里不仅有一个等号的操作，还有双等号。
-
So, we take our two equilibrium states, and you just put an equal sign between them, and the equal sign means go from one to the other.
我们写出两个平衡态，然后你只需要在它们之间放一个等号，等号表示,从一个过渡到另一个。
-
The question was, if you didn't hear, why do I have two equal signs?
这个问题是，如果你没听到问题的话，我为什么要用两个等号呢？
-
And that's why I use double equals.
这就是我用双等号的原因。
-
So, when you divide by m, m cancels and everything falls at the same rate on the surface of the Earth.
因此,当等号两边除以 m 时,m 被消去了,在地球表面的所有物体,都以相同的加速度下落
-
why don't I just use an equal sign?
不用一个等号么？
-
What does an equal sign do?
一个等号是用来做什么的？
-
And I'm using the so-called "assignment operator," a single equals sign to store in n what?
我用了一个复制操作符“,一个等号向n中存储了什么？
-
On the right-hand side, I'm going to write as a dx/dt.
在等号右边,我要写成dx/dt
-
And the reason that we now on the second line have the equal sign is because this function GetString has what's called a return value.
我们之所以,在第二行代码GetString前面加上等号,是因为这个函数会带回一个,返回值。
-
So this is the equality operator, whereas the single equal sign is the assignment operator.
所以这是相等操作符，然而那个单等号是一个赋值运算符。
-
So, when you divide by the mass to get the acceleration, you get the same answer.
因此,当等号两边除以质量来求加速度时,结果是相同的
-
The equal sign is really called the "assignment operator."
那个等号其实是个“赋值运算符“
-
It would be equal for the reversible case.
等号成立。
-
Turns out with a Boolean expression, you don't have use the equality operator equals equals, you can just say what you mean.
结果用一个bool表达式，你不需要使用等号操作符“==“了，你只要说出你的意思。
-
if it's a reversible process then the equality holds, but if it's irreversible, which means it happens spontaneously, T then dS is greater than this.
对于可逆过程，等号成立，但是如果是不可逆过程，这些不可逆过程是自发进行的，那么dS大于dq除以。
-
Or I'm canceling the 5 everywhere and changing the sign here I get t^-2t-3=0.
或者我在等号两边除以5,并变号得到t^-2t-3=0
-
As long as we understand that, we can do this cancellation and this says on the left-hand side the change in the quantity v square over 2 is a times the change in the quantity x.
只要我们明白这一点,我们就可以这样做简化,在等号左边,v^/2的变化量,为a乘以x的变化量
