I replaced Sr (and its PP file name) by Pb in the inputfile of SrTiO3 and
leave all other parameters unchanged. The odd problems (unconvergence and
large dielectric constant in plane) disappeared.

I should have made odd problem more clear here.  The dielectric constant
in plane reduced from 222.1 (using 4x4x8 k-point grid) to 6.380 
(4x4x4 k-point grid). The unconvergence problem came up in the 
phonon calculation of Representation # 24 (mode # 34). Pls see below. 
It seems that different k-point samplings can affect the results a lot. 
And so something of SrTiO3 is very sensitive to k-point sampling, though
I don't what it is.  Thank you very much for your help.
