Relative to the whole market, It's well known that over periods of multiple decades the market has a tendency to go up.

是和整个市场相关的对吗，我们都知道经过几十年的时间周期,市场会有上涨的倾向。

And then, just so that you will be literate in the rest of the Periodic Table, if you look at the higher ones, this is how you name them.

然后，你对周期表的,其他方面也都知道了，如果你观察高一点的元素，这是你们叫它们的方式。

So it looks like not too many more than half of you got this correct, so make sure you can look at your periodic table and figure out how to think about ionization energy in terms of z effective, not just in terms of memorizing what that trend is.

看起来只有一半多一点的人,做对了，所以请大家务必做到能够通过观察周期表,并在考虑电离能时,从有效核电量的观点出发，而不是仅仅依靠记住这个规律。

So, one that perhaps does not reproduce in such high numbers that you create an overwhelming infection, but one that still goes through its lifecycle but is limited in its effect.

因此,一方面这些病毒不会大量复制,从而不会导致暴发性的感染,另一方面,它依旧在进行生命周期循环,只不过对其效用进行了限制

So, how does average valence electron energy very across the periodic table?

那么平均价电子能,怎样才能对元素周期表产生很大影响呢？

Hopefully their immune systems will respond to it like the real virus but it won't be capable of replication because we've chemically cross linked it so it can't go through its life cycle.

人体的免疫系统,就会对该病毒产生免疫应答,但灭活的病毒不能复制,因为我们已经对它做了化学处理,使它无法进入生命周期

The period, that's right. So, it's going to take one period to move that long. And another way 1 we can say period is just 1 over nu or 1 over the frequency So, now we know both the distance traveled and the time the elapsed.

还是？周期，对的,它需要一个周期的时间,另一种说法是周期是,除以nu，也就是1除以频率,现在我们同时知道了。
