对于任意净电荷的情况，我们都可以这样做，比如假设我们有一个带两个正电荷的分子，那么所有的形式电荷加起来应该等于正二，等等。

So we can do this for any final charge we have, if we have a molecule that has a charge of plus 2, then all of the formal charges should add up to plus 2 and so on.

此外，还发现TPM染料所带的正电荷数以及取代基的体积是影响染料和G-四链体结合稳定性的两个重要因素。

Positive charges and substituent size in TPM dyes may be two important factors in influencing the binding stability of the dyes and G-quadruplexes.
