The asymptotic of curvature of direct image bundle associated with higher powers of a relatively ample line bundle

Let $\pi :\mathcal{X}\to M$ be a holomorphic fibration with compact fibers and $L$ a relatively ample line bundle over $\mathcal{X}$. We obtain the asymptotic of the curvature of $L^2$-metric and Qullien metric on the direct image bundle ${\pi }_{\ast }(L^k\otimes K_{\mathcal{X}\mathrm{/}M})$ up to the lower order terms than $k^{n-1}$ for large $k$. As an application we prove that the analytic torsion ${\tau }_k(\bar{\mathrm{\partial }})$ satisfies $\mathrm{\partial }\bar{\mathrm{\partial }}\log ({\tau }_k(\bar{\mathrm{\partial }}){)}^2=o(k^{n-1})$, where $n$ is the dimension of fibers.
