  We study the mass spectrum of the $\rm{q}^3\bar{\rm{q}}^3$ mesons both from
the quark model with triquark correlations and from common quark model with
colormagnetic interactions and with relative S-waves between quarks. Two
cluster configurations $(\rm{q}^3)-(\bar{\rm{q}}^3)$ and
$(\rm{q}^2\bar{\rm{q}})-(\rm{q}\bar{\rm{q}}^2)$ are considered. In the spectrum
we find rather stable states which have the same quantum number with particle
resonances which are corresponding to the $p\bar{p}$ enhancement,
$p\bar{\Lambda}$ enhancement and $\Lambda\bar{\Lambda}$ enhancement with
spin-$\mathbf{0}$ or $\mathbf{1}$. This imply these enhancements are NOT
experimental artifacts. The color-spin-flavor structures of $p\bar{p}$,
$p\bar{\Lambda}$, and $\Lambda\bar{\Lambda}$ enhancements are revealed. The
existence of spin-$\mathbf{1}$ $\Lambda\bar{\Lambda}, p\bar{\Lambda}, p\bar{p}$
enhancements is predicted.
