摘要翻译：
给出了非负Kodaira维数光滑射影曲面S$上所有具有常几何亏格G\geq2$和超椭圆正规化的曲线族的存在性限制。特别地，我们证明了一个Reider-like结果，它的证明是“无向量丛”，并依赖于形变理论和有理曲线的弯曲与断裂。我们也给出了这类曲线族的例子。

英文摘要：
We give restrictions on the existence of families of curves on smooth projective surfaces $S$ of nonnegative Kodaira dimension all having constant geometric genus $g \geq 2$ and hyperelliptic normalizations. In particular, we prove a Reider-like result whose proof is ``vector bundle-free'' and relies on deformation theory and bending-and-breaking of rational curves in $\Sym^2(S)$. We also give examples of families of such curves.
