Let $\{X_n,n\geq1\}$ be a $\wt{\rho}$-mixing
random variable sequence. By using the truncation method of random
variables and three series theorem of $\wt{\rho}$-mixing sequence,
the convergence properties of $\wt{\rho}$-mixing sequence are
discussed, and a class of strong limit theorems for
$\wt{\rho}$-mixing sequence are obtained, which generalize the
corresponding results of independent sequence. At last, the strong
stability for weighted sums of $\wt{\rho}$-mixing sequence is
studied
