So, when the value of the average valence electron energy lies between 11 eV and 13 eV, we have these elements that are neither fish nor fowl, and you'll see in a little bit their unique electrical properties.
所以,当平均价电子能,在11eV到13eV之间时,这些元素介于金属和非金属之间,你们将进一步,看到它们独特的电性质。
Right, because when we think of an energy diagram, that lowest spot there is going to have the lowest value of the binding energy or the most negative value of binding.
对因为当我们考虑,一个能量图时那里最低的点,是具有最低的结合能,或者最不活跃的结合能。
If it's there, I'm done, if not, I keep walking down, and I only stop when I get to a place where the element I'm looking for is smaller than the value in the list., in which case I know the rest of this is too big and I can stop.
并且保持遍历,我只在当当前位置的数组元素,大于目标数时停止,这意味着剩下的元素都比目标元素大,但是其他的情况,我还是要遍历完整个数组。
And we can go through and calculate the value of this quantity in parenthesis. And, when we do so, we get the value 2.18 times 10 to the minus 18 joules.
我们能进行计算这些值,如果我们这样做,我们能算出是,2。18,乘以10,的负18焦耳。
When they created margin rules that the seller had to be borrowing against securities. Just made more money when securities went up more value.
当我们发明保证金制度,卖空证券时需要交担保金,证券升值时能赚到更多钱。
It's the old gray but dark philosophy that you should just look at value But, one of the things is when people have given up on a company--that's the perfect time.
就是那个陈旧黑暗的哲理,你应该只注重价值,但是,还有一种情况当人们都抛售了,某个公司的股票--那就是个极佳的时机。
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。
Object versus value equality. Particularly when you use double equals, are you asking whether you've got the same object or the same value?
对象与值相等,特别是当你用==时,你得问问自己对象与值是否匹配?
So when I'm done, I'm going to give the value back out. All right?
当它完成计算后,需要返回个值对不对?
Incidentally, did I ever--equity equals shares or stock, so when I talk about debt-equity ratio, I'm talking about the ratio of the value of the company's debt to the value of all of its stock.
顺便说下,普通股就是股票,负债权益比就是,就是公司负债价值,除以股票总价值
We knew from Friday, when we talked about energy, that ground state was that n equals 1 value, that was the lowest energy, that was the most stable place for the electron.
我们上周五知道了,在讨论能量的时候,基态指,n等于1的态,它能量最低,是,最稳定的态。
I'll compute its value. Then I'll empty the backpack out, put another combination of stuff compute its value, try all possible ways of filling up the backpack, and then when I'm done, I'll know which was the best.
直至把它填满,然后计算价值,然后我把包里的东西都导出来,再换一堆东西计算它们的价值,尝试过所有填满包的方案后,我就知道哪一种方案是最好的了。
