These compounds include an ester bond making them sensitive to deactivation by esterases.
这些化合物包括使其对由酯酶引起的失活敏感的酯键。
At least until now the bond market had full confidence in U.S. bonds interest rates still being declined making the house lending rates also declined.
至少到目前为止,债券市场对美国债券还充满信心,美国债券的利率竟然还在下降,使得房子的贷款利率也下降。
At least until now, the bond market had full confidence in U.S. bonds, interest rates still being declined, making the house lending rates also declined.
至少到目前为止,债券市场对美国债券还充满信心,美国债券的利率竟然还在下降,使得房子的贷款利率也下降。
That's the huge force that we're talking about in terms of making a bond stable, but there are also repulsive forces, so you can imagine we're going to have electron-electron repulsion between the two electrons if we're bringing them closer together.
正是这个非常强的力,使得我们所讨论的这个键能够稳定存在,但是其中还有排斥力存在,大家可以想象一下,我们会有电子与电子之间的排斥力,如果让它们离得更近。
So, we see is when we use the octet rule to look at fluorine molecule, we're combining two fluorine atoms, and what we end up with is an f f molecule where they're sharing two electrons, so making that covalent bond.
那么,我们看到把八隅体规则用到氟分子上,就是把两个氟原子组合起来,最终得到的氟分子中两个原子,共用一对电子,这就构成了共价键。
