Well, we would have to H+ have one of these hydrogen atoms go to an H plus, * plus an electron, right? **H --> H+ + e-** So, now we have a hydrogen ion here.
我们先要让,一个氢原子变成氢离子，加上一个电子，对么*,我们现在有一个氢离子了。

Based on the lessons we've been telling if I say *, you know what I have a computer.
基于我们讲过的课程，如果我指明，我有一台计算机。
-
I have *.
我得到*
-
I have 3 q1* is equal to a - c over b; and finally divide by 3 q1* is equal to a - c over 3b.
q1*= /b,最后两边同除以3得,q1*=/3b
-
*10^-18 1.6 times 10 to the minus 18, excuse me, 6*10^-19 we have 1.6 times 10 to the minus 19, 2.18 times 10 to the minus 18, etc.
。,1。,2。18*10^-18，等等。

Now, we're not quite there because now we have two copies *b=temp of 2 so the last line of code says *b gets temp.
现在，我们还没有达到目的，因为现在我们有两个2的拷贝,最后一行指明。
-
* So at top left we have a slash and a star - and that says everything that follows that-- those symbols is just a comment.
在左上角，大家可以看到,这是用来告诉大家，所有跟在它后面的-,标记都只是注释而已。
-
*2=6 So I have three times two is six.
由于。

> Student: >> David: And the * will have other powers that we'll soon see.
>，学生：【听听不清的】,>>，大卫：我们将看到,那个*还有其他的功能。
-
int *x So I have int *x.
所以我用。
-
Because we just have to reason through now what the * notation actually means.
我们刚捋顺了,号是什么意思。
-
If you go and work that out, log2 log of two and you have two log two, by math you can show that for the line r series m 2*log2 is equal to two natural log of two, which is 1 1.386 which is greater than one.
如果你把它计算出来，这二者的对数，你会得到2个，通过数学，你会得到第r列，第m个值,等于,也就是1。386，这大于。

And conceptually, the idea of cubing a value feels like you could package that up into a little box, a little tool that takes input, a value, and returns output the answer A* so you don't have to constantly do A star, A*A So this program ,at the end of today, is pretty much the same thing.
概念上，算一个值的立方就像是,你可以把一个值打包放在一个小盒子里,一个用来接收输入的工具,一个值，然后返回一个答案,所以你并不需要一直使用，等等。，A，star，，A，，and，so，forth。,这个程序，最后，是一个差不多的东西。

It may mean something different and this is sort of just stupid re-use of syntax although frankly it wouldn't really be much fun to have yet a symbol so they went with the same symbol which is pretty reasonable in the context *a of a function prototype this just means *a expect A to be the address of an int and expect B to be the address of an int.
这里的意思有点不同,这是为了重使用的目的,虽然这个符号没有什么意义,所以在函数原型中，他们就使用了相同的符号,这只是表示，期望,是一个int型的地址,期望b是一个int型的地址。
