摘要
本文报道了干、湿两种牛密质骨在动力加载情况下SGP和应变、应变串间相互关系的实验研究。实验中采用了传统的SHPB技术,发现湿骨中SGP有明显的滞后现象,实验支持在湿骨中把流动势看作SGP的主要根源的观点。
<ABSTRACT>
This paper presents results of experimental studies on relationship be-
tween SGP, strain and strain rate in both wet and dry bovine femora at
high strain rate. A classical dynamic material testing device, split Hop-
kinson pressure bar, was used to observe transient electromechanical be-
haviour in bone and a time delay of the SGP vs the strain history is
clearly observed. It seems that the experimental data support that the
mechanism of streaming potential is the main source of SGP gencration
in wet bone.
