  People extend the MSSM with the local gauge group $U(1)_X$ to obtain the
$U(1)_X$SSM. In the framework of the $U(1)_X$SSM, we study the flavor
transition process $b\rightarrow{s\gamma}$ with the mass insertion
approximation (MIA). By the MIA method and some reasonable parameter
assumptions, we can intuitively find the parameters that have obvious effect on
the analytic results of the flavor transition process $b\rightarrow{s\gamma}$.
By means of the influences of different sensitive parameters, we can obtain
reasonable results to better fit the experimental data.
