sigma2sp It's going to be a sigma bond. So, we have sigma 2 s p, carbon 2 s p. So they're two s p bonds combining.
是sigma键，我们有，碳2sp。，所以它们是两个sp键结合。
Separately, S&P yesterday lifted its outlook on the U.S. life insurers to “stable” from “negative, ” saying the industry may sidestep downgrades next year after raising funds in stock and bond sales.
标准普尔昨天把美国保险企业的预期从“负面”上调为“稳定”，表示美国保险企业经过发售股票筹集资金和债券出售后，可能在明年避免评级遭到下调。

标准普尔昨天把美国保险企业的预期从“负面”上调为“稳定”，表示美国保险企业经过发售股票筹集资金和债券出售后，可能在明年避免评级遭到下调。
That's because S&P is expected to follow its U.S. downgrade with cuts in ratings of some muni bond issuers, particularly states that get significant amounts of federal funding.
因为继美国国债评级下调之后，预计标普会降低这些市政债券的评级，尤其是那些拥有庞大联邦基金的州。
So it's along the bond axis and it's between a carbon s p 2 hybrid, and then the hydrogen is just a 1 s orbital that we're combining here.
所以它是沿着键轴方向的,而且这里是一个碳sp2杂化轨道，和一个氢的1s轨道的结合,在这里我们可以合并他们。
So it already should make sense why we have that p orbital there, in order to form a pi bond, we're going to need a p orbital.
这里有p轨道是很合理的,为什么我们在这里有P轨道，为了形成一个π键，我们需要一个p轨道。
So we can kind of flip it this way this will be one pi bond, this will be another interacting between these p orbitals.
我们可以把它这样翻一下,这是一个π键，这是另外一个p轨道之间,相互作用的π键。
The original strategy involved investing half of an investor's assets in an S&P 500 Index fund and half in a fund mirroring the Shearson/Lehman Intermediate Bond Index.
原始的策略包括投资者将一半的资产投到标准普尔500指数基金(S&P 500 Index Fund)，另一半投到希尔森-雷曼中期债券指数(Shearson/Lehman INtermediate Bond Index)。
P the spacing of bars shall be such that the concrete can be placed and compacted satisfactorily for the development of adequate bond.
钢筋间距应考虑钢筋的放置和混凝土的压实，并且混凝土和钢筋能形成足够的粘结性。
At the above condition, relative P-Bond shall be forfeited.
在上述条件下，相应的履约保证金无效。
The electronic structure of the series are calculated by INDO and the nature of high energy P—O bond in biological chemistry is discussed.
采用量子化学INDO方法计算了系列物的电子结构，依据计算结果讨论了生物化学中高能磷酸键的本质。
The reactive species, which may be a free-radical, adds to a monomer molecule by opening the p-bond to form a new radical.
这个带有自由基的反应种通过打开双键加入到单体分子上，从而形成新的自由基。
P The surface characteristics of ribbed bars shall be such to ensure adequate bond with the concrete.
带肋钢筋的表面必须保证其与混凝土的充分粘性。
P the calculation of the required anchorage length shall take into consideration the type of steel and bond properties of the bars.
所需的锚固长度的计算应考虑到钢的类型和钢筋粘结性能。
Markets are bound to remain highly jittery, although it seems unlikely that American bond yields will rocket as a result of the S&P downgrade.
尽管由于标普对美国主权债务下调了评级不太可能引发美国国债率利率的飙升，但目前市场还是保持着高度的恐慌心理。
