So if we have total +2 and complete shielding -1 where that can actually negate a full positive charge, because remember our nucleus is plus 2, +1 one of the electrons is minus 1, so if it totally blocks it, all we would have left from the nucleus is an effective charge of plus 1.
抵消一个完全的正电荷,因为记住我们的原子核是,其中一个电子是,所以如果它完全挡住了它，我们从原子核中留下的，全部有效电荷就是，所以，在我们的第一个例子中,我们的第一种极端情况。

We're not interested in talking for talking's sake." "We're looking to see through an early meeting, should Iran be willing, we'd be looking to see if they are willing to engage seriously on these issues but within the context of the P5+1 the full range of issues that we have among these countries and Iran."

I can't give it what it wants," know that when you're writing code and the problems that will remind of this, if you absolutely have to kill your program, you don't have to close the window, CTRL+C reboot crazy stuff like that, generally you can hit CTRL+C and it will just abort the program right where it is, in case you ever get trapped in some awkward situation.
我不能给它所要的“,当你在写代码时，程序将,提醒这个问题，如果你不得不,关闭这个程序，你不需要关闭这个窗口，重启像那样的疯狂举动，通常你可以敲,它将会在这个地方终止那个程序，假使你陷入了尴尬的处境。

As reported contemporaneously in 2000,the number was -3.1% but if you look at the number reported for 2005, because bad records had disappeared and good records had been added, all of a sudden the average experience for that year went up to +1.2%.
000年期的公告中这个数字为负3.1%,但是如果你去查2005年公告的数字,坏记录已经调整而消失,有利的投资记录被加入,转瞬之间,年平均收益升至1.2%

See, I've defined f of x to be a function x=x+1 that takes a value of x in, changes x to x+1, x and then just returns the value.
我定义了f是一个函数,输入x，让，然后输出。

If you want to call something as A + B, it means that I did A and then I did B.
如果你想某个量称为 A + B,它表示我先沿着 A 走,然后是 B

We put the magnesium 2 plus here, and then we put the oxygen here, O 2 minus, and we know that this gives us our R zero, right?
我们把Mg2+放这，然后O2-放这，我们都知道这给我们的是R0，对么？
-
I personally don't like swings that much and it's the B-/B+ range, so I'd much rather prefer that to a swing from A to C, and that's my reason.
我不喜欢成绩波动很大的,比如B-/B+这个范围,所以我还是喜欢像A到C这样小点的,这就是我的原因

And then on the right hand side I++, we saw that in pseudocode with our socks example last week that just says increment I.
然后是最右边的i++，我们上周在socks例子的伪代码中,曾经见到过，不是么？只是代表i加1而已。

If you are describing a particle with location R, the vector we use typically to locate a particle, R then R is just i times x + j times y, because you all know that's x and that's y.
如果你要描述一个位移为 R 的质点,这个矢量一般用表示质点 R 的位移,R 可表示为 i ? x + j ? y,显然你们都知道这段是 x,那段是 y
-
Then, to find the meaning of b, we take one derivative of this, dx/dt, that's velocity as a function of time, and if you took the derivative of this guy, you will find as at+b. That's the velocity of the object.
接下来,为了弄清b的含义,我们取它的一阶导数,dx/dt,得到速度作为时间的函数,如果你对它求导的话,你会得到at+b,这就是物体的速度
