在宇宙弦理论中，一小部分弦环可能会坍塌形成黑洞。本文考虑了涉及黑洞的这类模型的各种约束。重新分析了来自黑洞的霍金辐射、伽马和宇宙射线通量限制以及可能形成稳定黑洞残骸的约束。从这些考虑中出现的约束与宇宙弦模型到宇宙微波背景各向异性的归一化得到的约束非常接近。{版权所有}{ital1998}{italthe American Physitive Society}
In theories with cosmic strings, a small fraction of string loops may collapse to form black holes. In this paper, various constraints on such models involving black holes are considered. Hawking radiation from black holes, gamma and cosmic ray flux limits and constraints from the possible formation of stable black hole remnants are reanalyzed. The constraints which emerge from these considerations are remarkably close to those derived from the normalization of the cosmic string model to the cosmic microwave background anisotropies. {copyright} {ital 1998} {ital The American Physical Society}
