我们考虑两个离散弦理论模型，其作用取决于外在曲率，并证明当外在曲率的耦合强度趋于无穷大时，弦张力消失。我们讨论了模型的物理属性，并认为它们具有不平凡的缩放限制。
We consider two models of discretized string theories with an action which depends on the extrinsic curvature and prove that the string tension vanishes as the coupling strength of the extrinsic curvature tends to infinity. We discuss the physical properties of the models and argue that they possess a nontrivial scaling limit.
