  We investigate the CP violation in the decay process $\bar B_{s} \rightarrow
\phi(\rho,\omega) P \rightarrow K^{+}K^{-}P$ by considering the interference
effects of $\phi\rightarrow K^{+}K^{-}$, $\rho\rightarrow K^{+}K^{-}$ and
$\omega\rightarrow K^{+}K^{-}$ within the framework of perturbative QCD method
(P refers to $\pi$, K, $\eta$ and $\eta'$ pseudoscalar mesons, respectively).
We analyse the mixings of $\phi-\rho^{0}$, $\phi-\omega$ and $\omega-\rho^{0}$
and provide the amplitudes of the quasi-two-body decay processes. The CP
violation for $\bar B_{s} \rightarrow K^{+}K^{-} P$ decay process is obvious at
the ranges of the three vector mesons interferences. Meanwhile, the localised
CP violation can be found for comparing with the experiment results from
three-body decay process at the LHC in the near future.
