Hello, Shuaiwei:
Please do not send e-mails to individuals on the board—particularly someone who wasn’t involved with the development of the feature in question!
I’m not familiar enough with the COMB potential, or the Wolf summation method used by COMB, to comment—particularly since this appears to be an issue with the files providing the potentials, not the way the command is implemented in LAMMPS. Either Steve or Tzu-Ray Shan (UF), the primary author of the command, should discuss this.

I want to use “Wolf summation method”for the long−range Coulombic term，what shold I do？
I don't know what this means. If you want to use the COMB potential,
then just use it and it will do these calculations. Or are you asking
something different?

I think the OP wants to know if Zn potentials are actually included in the COMB force field file, or if it’s a typo in the documentation. . . .

If you asking about Zn in COMB, then check the potential file and dcc page.
If you have a question about that, then post it, or better yet, contact
the COMB author who is listed in the pair_comb.cpp file.
