  摘要: In this talk, we first introduce a class  of  non-weight  modules over   the N=1 Heisenberg-Virasoro superalgebra $\mathfrak{g}$, which are reducible modules.  Then we give all submodules of such modules, and present the corresponding irreducible quotient modules. Also, we prove that those modules constitute a complete classification of     $U(\mathfrak{h})$-free modules of rank $2$ over $\mathfrak{g}$, where $\mathfrak{h}=\C L_{0}\oplus\C H_{0}$ is a degree-0 subalgebra  of  $\mathfrak{g}$. As an application,  we   obtain a class of weight $\mathfrak{g}$-modules      from those non-weight $\mathfrak{g}$-modules by the  weighting functor. Furthermore,  we study the  non-weight modules  over the four  subalgebras of $\mathfrak{g}$: (i) the Heisenberg-Virasoro  algebra; (ii) the Neveu-Schwarz algebra; (iii) the Fermion-Virasoro algebra; (iv) the Heisenberg-Clifford superalgebra.
