It was found that, if the interval between the electron and the donor ion was different, the variation of polarization potential with the donor ion position z_0 in the PQW would be different also.

结果表明，电子与施主离子间的距离不同，则极化势随施主离子位置的变化关系也不同。

Thus could be resulted from the complexation by which increases the electron density of the metal ion through partial sharing of its positive charge with donor groups.

主要原因可能是形成配合物后电子由配体流向配位的中心阳离子，增加了电子的转移能力。

So, I've got ion pair formation, and I've got a huge decrease in energy because a donor is able to express that urge, an acceptor is able to express that urge.

所以我能得到形成的电子对，同时能量也大幅下降,因为失电子方要表达它的迫切，得电子方也要表达它的迫切。
