>  thank you very much. one more question: there is about 100 atoms/unitcell in my system, after input one k-points in the BZ, it generates 2 k-mesh in the IBZ. Is this possible? I post the klist file here: 1    0    0    0    2  1.0 -7.0  1.5         1 k, div: (  2  1  1)
>  2    1    0    0    2  1.0

Yes it is possible (although it sounds unlogical). The program uses internally
some "normalizer" and then finds out that you have one short and two long
directions, which leads to these 2 k-points.

If you don't like it, use just one k-point and some broadening method for EF.
