Let me add, let me make it 17 people so we have an odd number, so go and sit in that row.
我再加一个人这样就是奇数17个人,请到那行中
And what I am going to do is say start with this ion, add up the energy associated with the interactions between that ion and everybody else in the row and then multiply it by Avogadro's number, because that is the number of atoms there are in a row.
接下来我要从这一离子开始,加上相互作用的能量,也就是这一离子,和其它所有在这一行的离子之间的能量,再乘以阿伏加德罗常数,因为这是在一行的原子的数量。
In the final hours of debate on the Senate bill, Republicans asserted it would be ineffective and add sharply to the U.S.budget deficit.

Let me also add that I have a reading list that has clickable things on it and also things that are on reserve in the library.
还有一点,我还有个阅读材料列表,其中有可点击的网络连接,也有可以在图书馆读到的内容
To get any location in memory, to get to any value of the list, I simply have to say which element do I want to get, I know that these things are stored in a particular size multiply that index by 4, add it to start, and then it's in a constant amount of time I can go to that location and get out the cell.
取得列表中的任何一个值,简单说来,想要取得列表中的任何元素,我知道这些元素存在特定的大小中,把下标乘以4,加到start上,然后定位到内存单元,并取出值就是固定的时间了,好的,如果元素以固定大小存储。
You can add something else to the answer without invalidating it, and that is anything with one power of t in it, because if you take one derivative it'll survive, but if you take two derivatives, it'll get wiped out.
你可以往答案后面加上其它东西,而且不影响结果,也就是任何t的一次项,因为你求一次导数之后它还在,但如果你求两次导数,这一项就不存在了
