We don't usually do our chemistry calculations in miles per hour, so let's switch that to 42 meters per second, so it's -- sorry, it's 94 miles per hour.

在化学计算中我们很少,用英里每小时，所以我们把它换算为42米每秒，对不起，它是94英里每小时。

Remember, all you have to do is fill in the one or two-letter abbreviation for the chemical symbol.

记住，你们只要,用一两个字母的缩写,来代表化学元素就可以了。

All right. So hopefully we're pretty comfortable naming any type of wave function using the chemist terminology.

好了，希望我们都可以,接受这种,用化学术语来命名任何类型的波函数了。

Right? In other words I've got the stoichiometric coefficients in there and the values, and I'm subtracting the reactants from products -1652kJ/mol wind up with minus 1652 kilojoules per mole.

对吧？换句话说这里我用了化学,计量系数和生成热的值，从生成物中减去反应物,最后得到。

You are required only to put the one or two-letter chemical abbreviation, the symbol.

你们只需要,用一两个字母来代表一个化学元素。

And so, he has put this chemistry to use in this robotic arm and they call it Fido, because often dogs are the creatures that have to go out and detect these things, and it's not a great job if you're a dog to be sent out to see whether there was an explosive and discover yes, there was, a little bit too late.

因为通常都是派狗去检查这些东西,这个不是个好工作，如果你是一只狗,被派去检查是否有爆炸物，然后你发现有,那就来不及了,所以用机器手检查化学物质。

And when we describe this in terms of talking about chemistry terminology, we would call the first one the 1 s, and 1 is in parentheses because we're talking about the first electron there, and we would multiply it by the wave function for the second one, which is also 1 s, but now we are talking about that second electron.

当我们用化学术语来,描述它的时候，我们称第一个为“1s“,括号中的1是因为我们,在谈论第一个电子,而且我们会用它的波函数，乘以第二个,第二个也是“1s“,但是我们现在谈论的是,第二个电子。
