I don't how to use "bsse" in QM/MM? Who can tell me how to write the nw file ? (QM/MM with bsse)

I am not sure what you mean by QM/MM "bsse" simulations. There is no mechanism right now to place basis sets on classical Bq charges, which will probably make "bsse" calculations unfeasible through "standard" QM/MM route.

Re
I have put ligand and a residue's side chain into the QM region, I want to calculate the delta E between the ligand and this residue. As in QM, the calculation method is deltaEab=Eab-Ea-Eb+BSSE. So I want to use this method in QM/MM simulation.

It would not be possible to do it directly. One possible route would be use Bq charges that are generated during QM/MM (ab) calculation, load them and perform standard QM BSSE calculation.
