3-d hydrogen-bond 三维氢键
The bank said Thursday that the fast-food giant was raising 200 million yuan ($29.5 million) with a three-year bond that will pay 3% annual interest.
该行周四透露,这家快餐巨头将以3%的年息销售这一笔三年期的债券、以此募资2亿元人民币。
The yield on the 3 percent bond maturing in December 2013 gained four basis points to 3.39 percent, the highest level for a benchmark three - year note since Nov. 23.
2013年12月到期债券收益率由3%上涨4个基点至3.39%,是为基准3年期国债11月23日以来的最高水平。
Risk aversion has sent the 10-year Treasury bond yield below 3%.
风险规避已经使10年期长期国债收益率低于3%。
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。
So we know that it's 1, because we have 1, 2, 3, 4 bonding, minus 2 anti-bonding, and 1/2 of that is a bond order of 1.
我们知道它是,因为我们有1,2,3,4个成键,减去2个反键,它的一半就是键序为1。
We see three bonding pairs so this is a triple bond, indeed a multiple bond.
我们看到3对成键电子所以这是一个三重键,它确实是多重键。
