So a two-year bank CD or a Treasury inflation-protected security yielding around 2%, and short-term investment-grade bond funds at 2% plus, aren't the end of the world.
因此收益率在2%的两年期银行定存单或者通货膨胀保值型国债,以及收益率在2%以上的短期投资级债券基金都属于不错的选择。
Take a bond with a 2% real yield maturing in ten years’ time; the bond will pay an initial $20 on a face value of $1, 000.
购买一份真实收益率为2%的10年期债券,当面值为1000美元时,债券最初付息是20美元。
You may think otherwise, given the markets' fevered concern over the “monoline”[2] bond insurers.
但大家可能不这样想,大家往往高度关注债券市场中的市政债券保险商。
/2 So the bond order is going to be equal to 1/2, and then it will be 2 minus 2.
它的键序等于,然后乘以2减去2。
And if we put that in our bond here, we have 1, 2, 3 bonds, plus we have one lone pair left over.
如果我们把它们放到键里,我们有1,2,3个键,还剩下一对孤对在这里。
The way that we can figure this out is using something called bond order, and bond order is equal to 1/2 times the number of bonding electrons, minus the number of anti-bonding electrons.
我们可以用叫做,键序的概念来弄明白它,键序等于1/2乘以成键电子,数目减去反键电子数目。
