Abstract: We study the Fourier-Mukai numbers of rational elliptic surfaces. As its application, we give an example of a pair of minimal $ 3$-folds with Kodaira dimensions $ 1$, $ h^1(\mathcal O)=h^2(\mathcal O)=0$ such that they are mutually derived equivalent, deformation equivalent, but not birationally equivalent. It also supplies a counterexample of the birational Torelli problem.
