I am going to say if that electron is to stay in its orbit, that is to say it doesn't flee the atom, it doesn't collapse under the nucleus then the sum of the forces on the electron must be zero No net force. And so that will be the sum of a dynamic force plus an electrostatic.
如果电子会保持在它的轨道上运行,既不脱离原子的话，它就不会由于原子核对它的吸引力而被瓦解掉,电子所受的合力一定为零,由于没有合力,所以电子所受力为动态力和静电力的总和。

You can start from one nucleus and go to the next nucleus, and there are no zero planes, no nodes, nothing.
你可以从一个核出发,看向另一个核，中间没有零平面，没有节点，什么也没有。

Yes or no. That can give you a true or false, a one or a zero answer. What about this?
是或者否，它告诉你真假，1，或，0，这个怎么样？

Secretary of Defense Robert Gates said that while no one expects the world will achieve the goal of "zero nuclear weapons" anytime soon, the new treaty is a major step toward greater security with fewer nuclear weapons: "It is clear that we can accomplish goals with fewer nuclear weapons."

And what that corresponds to, if you recall, is the idea that in a perfect crystal at zero degrees Kelvin then you have no disorder at all.
如果你们能回忆起来的的话，这就意味着,绝对零度下的完美晶体,一点无序状态也没有。
-
And the bond order you get out will either be, for example, zero, which would mean that you have no bond, 5 or you could have 1, a single bond, 1 . 5, a 1 and 1/2 bond, 2, a double bond, and so on.
你得到的键序要么是比如说是零，这意味着没有键，或者你会得到1，单键1。,1又二分之一键，2，一个双键，等等等等。

Well, we already saw no, 0 if my initial guess is zero, I don't get anywhere.
我们已经说了不是了，如果我的初始猜想点是。

Then it lands on your foot, because assuming the cannon is at zero height, the cannonball certainly comes out towards the enemy, but has no time of flight.
然后它就会落在你的脚边,因为假设大炮的高度为 0,炮弹笔直地出膛打向敌人,却没有时间飞行

No positive number, no negative number. That's a zero.
没有正数，没有负数，只是个零。
-
And this puzzle piece here colored in blue because it's a Boolean expression is just something that--whose answer is either a yes or no, 0 true or false, one or zero.
这个拼图染成蓝色,因为它是布尔表达式,它的结果只可能是肯定或否定，对或错，1或者。
-
There's no decimal point; there's no point zero; there's no floating point value, it's just a hardcoded integer.
这里没有小数点，这里没有;,这里没有浮点数值，它只是一个整型数字。
-
Right, 'cause that means either I've been handed zero elements which mean there's really no work to be done or I've been handed one element which is a vacuous truth that it's sorted, right?
因为如果给出0个元素,那意味着不需要做任何事,如果给出1个元素，那显然,它是有序的，对吗？
-
And so the energy is zero because the electron is no longer bound. It is free.
所以这个系统能量为0，因为,电子不再受束缚了，它自由了。
-
And, so you propose that there is no, that this derivative is zero, and that the internal energy is given simply by this quantity.
你认为这是零，这个微分是零，内能仅仅由,这个简单的量决定。
-
And there is no work done on the surroundings because pressure is zero.
这里系统没有对环境做功,因为压强是零。
-
Maybe not. It has no protons, so therefore, it has no electrons Because proton number equals electron number, which means if it has no protons 0 its atomic number is zero.
也可能不会，这个元素没有质子，因此，也没有电子,因为质子数等于电子数，意味着它没有质子,它的原子序数为。
-
If there's no work to be done, 0 the running time is gonna be zero.
如果并不需要做什么，那么其运行时间肯定为。

Zero, there's no lab.

So it does that for us so that you can get away with just knowing the address of the first byte and it will make sure that you know when to stop by including the special value so, in fact, get the string if you type in a three-letter word, we allocate four bytes no matter what because we need an additional byte 0 for this special sentinel value back slash zero at the very end.
它为我们做了这些事情，这样我们就可以,通过第一个字节的地址,它还可以通过包含一个特殊的值,来保证在哪里停止，如果你输入了一个三个字母的单词,就可以获得那个字符串，不管怎样，我们分配四个字节,因为我们在末端需要一个额外的字节,来保存这个特殊的标志值--反斜杠。
-
Did no work. Does that mean du is zero?
没有对外做功，这是否意味着du=0？
-
And it's p external and p external is zero, so there's no work.
外部的p是零，所以结果是零，没有做功。
