Planck Galactic Cold Clumps in Two Regions: the First Quadrant and the
  Anti-Center Direction Region
  Sixty five Planck Galactic cold clumps (PGCCs) from the first quadrant
(IQuad) and thirty nine of PGCCs from the Anti-Center direction region (ACent)
were observed in $^{12}$CO, $^{13}$CO and C$^{18}$O J=1-0 lines using the PMO
13.7-m telescope. All the targets were detected with all the three lines,
except for 12 IQuad and 8 ACent PGCCs without C$^{18}$O detection. Seventy six
and 49 velocity components were obtained in IQuad and ACent respectively.
One-hundred and forty-six cores were extracted from 76 IQuad clumps and 100
cores from 49 ACent clumps. The average T$_{\mathrm{ex}}$ of IQuad cores and
ACent cores are 12.4 K and 12.1 K, respectively. The average line width of
$^{13}$CO of IQuad cores and ACent cores are 1.55 km s$^{-1}$ and 1.77 km
s$^{-1}$, respectively. Among the detected cores, 24 in IQuad and 13 in ACent
have asymmetric line profiles. The small blue excesses, $\sim$0.03 in IQuad and
0.01 in ACent, indicate that the star formation is not active in these PGCC
cores. Power-law fittings of core mass function to the high mass end give
indexes of -0.57 in IQuad and -1.02 in ACent which are flatter than the slope
of initial mass function given by \citeauthor{1955ApJ...121..161S}. The large
turnover masses with value of 28 M$_{\odot}$ for IQuad cores and 77 M$_{\odot}$
for ACent cores suggest low star formation efficiencies in PGCCs. The
correlation between virial mass and gas mass indicates that most of PGCC cores
in both regions are not likely pressure-confined.
