First you cannot normally expect two in the same AU have the same
structure, so an over-weighted averaging may cause bias.
It is likely that a rigid-body refinement down to two molecules or
even domains may help improve in your case.

ni hao,
I have a question about how to improve the electron density. I have two

For the first molecule, the density is very good, but for the second one,
