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。
Two of the three main credit-rating agencies, Fitch and Standard & Poor’s (S&P), cut their rating on Greek bonds and gave warning that a further downgrade was likely.
