We offer what is an increasingly rare commodity, which is a triple A rated government bond with the icing on top the highest yield on those top-rated bonds, he said. 他表示:我们提供的是一种越来越稀有的商品,那就是AAA评级的政府债券,锦上添花的是,它们在最高评级债券中拥有最高的收益率。
An unsaturated fatty acid whose carbon chain has more than one double or triple valence bond per molecule; found chiefly in fish and corn and soybean oil and safflower oil. 碳链的分子均有多个二价或三价键的不饱和脂肪酸,主要存在于鱼、谷物、大豆油和红花油中。
Unbranched hydrocarbons having one triple bond are named by replacing the ending-ane of the alkane name with-yne. 直链的、有一个叁键的烃可通过将其相应烷烃名字的词尾–ane改换为-yne而得。
So, if we talked about a nitrogen-nitrogen single versus double versus triple bond, the triple bond will be the shortest and it will be the strongest. 因此,如果我们讨论的是氮与氮之间的单键,双键与三键,那么三键应该是其中最短的一个,同时也是最强的一个。
It is a truism that triple A rated bonds are risk free in the sense that the actual return on the bond is the same as the expected return. 就债券的实际回报率等于预期回报率这个意义而言,AAA级债券是无风险债券,这一点不言自明。

And something that we'll see later on is that triple bonds, for example, are going to be stronger than a corresponding double bond or a corresponding single bond. 而我们以后还会看到三键,举例来说,应该更强,相较于相应的双键,或者相应的单键来说。
The triple bond does not usually react so vigorously at a carbon-carbon double bond. 三键在反应时一般不象烯烃中的碳-碳双键那样剧烈。
A triple bond, again is going to have one sigma bond on the internuclear axis. 一个三键,同样的也有沿着核间轴sigma键。
The EFSF last week obtained a triple A rating, which will help it raise cash in the bond markets at good rates. 上周,EFSF获得了AAA信用评级,这有助于其在债券市场以优惠利率筹集资金。
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。
