### Abstract

Let $\mathbb{Z}/(p^e)$ be the integer residue ring modulo $p^e$ with $p$ an odd prime and $e\ge 2$.We consider the $s$-uniform property of compressing sequences derived from primitivesequences over $\mathbb{Z}/(p^e)$. We give necessary and sufficient conditions fortwo compressing sequences to be $s$-uniform with $\underline{\alpha}$ provided that the compressing map is of the form$\phi(x_0, x_1, \ldots, x_{e-1})=g(x_{e-1})+\eta(x_0, x_1,\ldots, x_{e-2})$,where $g(x_{e-1})$ is a permutation polynomial over $\mathbb{Z}/(p)$ and $\eta$ is an $(e-1)$-variablepolynomial over $\mathbb{Z}/(p)$.
