Dear ajlu@ustc.edu,

Please let me reiterate,
Kindly look into your log file, and let us know what ABINIT
complained there (as "WARNINGS"). Especially, regarding "nstep 10"
(SCF cycle reached 10 or not ? If nstep is increased to, say, 50, what will happen ?)

Could you please peruse the Netiquette ?
(You could attach some extracted results ... in gzip form)

Regards,
Masayoshi

Thanks a lot. But I need furhter help yet.

1. I used TM psp download from website. It works well for silicon band structure calculation with 2 atoms (primitive cell). So I think it's okey to be used here.

2. I did not pay attention to the special point label in the reciprocal lattice. Thanks for your suggestion. In fact, I care for the Gamma point mainly, but the problem just occurs at this point.

3. 32 k points are calculated, and there are no warnings in the log file. So, I can not find other useful clues to revise my input file.

Thanks again.
