We have recently reported the insensitivity of tensile failure properties of human cerebral bridging veins to strain rate. Due to data scattering, however, concerns remain regarding this finding. To pursue the issue further, the common carotid arteries and external and internal jugular veins from seven ferrets were stretched longitudinally in vitro at either a low strain rate of 0.2-2.0 s-1 or a high rate of approximately 200 s-1. The ultimate stretch ratios and loads were found to be independent of strain rate in all the vessels tested. Therefore, the present results appear to support our previous finding on human bridging veins.
我们最近报告了人脑桥静脉拉伸破坏特性对应变率不敏感。然而，由于数据分散，这一发现仍存在疑问。为进一步探讨该问题，对7只雪貂的颈总动脉、颈外静脉和颈内静脉进行体外纵向拉伸，拉伸应变率分别为低应变率0.2 - 2.0 s⁻¹或高应变率约200 s⁻¹。结果发现，在所有测试血管中，极限拉伸比和负荷均与应变率无关。因此，目前的结果似乎支持我们之前关于人桥静脉的发现。
