And the constant, if we redo it in modern SI units, 1 would take on the value of 1.1 1*10^7m-1 times 10 to the 7th reciprocal meters.
如果我们用现代国际单位制来改写它，这个值是1,1。

But in terms of SI units, which become much more useful if you're actually trying to use intensity in a problem and cancel out your units, we're just talking about joules per second is what intensity is.
但是用国际单位制，这个变得越来越有用了,如果你实际上在使用强度,来解决问题和约化单位，我们仅仅讨论每秒钟的焦耳,这就是强度。

It is not an SI unit because it is not a multiple of 10 to the 3rd, but I like the angstrom.
它不是国际制单位，因为它不是,10的3次方进制，但我还是喜欢这个单位。

So, in particular, if you're person 1 and then "s-i" would be "s2, s3, s4" up to "sn" but it wouldn't include "s1."
具体来说如果你是参与人1那么,si-可能表示s2,s3,s4,直到sn,但是不包括s1

Notation: so I'm going to use little "si" to be a particular strategy of Player i.
表述法,我们用小写si来表示参与人i的某个策略
-
Now I need to distinguish this from the set of possible strategies of Player I, so I'm going to use capital "Si" to be what?

How do we think of that term B S1 S2?

So to say it in words, Player i's strategy "s'i" is strictly dominated by her strategy "si," if "si" always does strictly better -- always yields a higher payoff for Player i -- no matter what the other people do.
用文字来描述就是,参与人i的策略s'i严格劣于si,如果si总是更好的选择,即总能给参与人i带来更高的收益,而无论其他参与人怎么选
-
I'll say it again, Player i's strategy "s'i" is weakly dominated by her strategy "si" if she always does at least as well by choosing "si" than choosing "s'i" regardless of what everyone else does, and sometimes she does strictly better.
重申一下,参与者i的策略s'i,弱劣于策略si,当且仅当无论对手怎么做,她选择si的收益至少与选s'i的相等,有些情况下甚至是严格占优的
-
So strategy ?i is a best response to the strategy S-i of the other players if my payoff from choosing ?i against S-i, is weakly bigger than that from choosing Si' against S- i, and this better hold for all possible other strategies I could choose.
策略?i是其他参与人策略S-i的,最佳对策,如果此时我选?i的收益,弱优于此情况下选Si'的收益,这对于所有我可以选择的策略都成立
