| 摘 要： | 为得到肌张力特性与其电生理特性间的实验关系,本文在0.1 ms的波宽下,用不同频率的三种强度的重复脉冲电流,对家兔的胫神经进行电刺激,用生物材料试验机和肌电仪记录其腓肠肌的肌张力和复合动作电位.结果表明,肌张力与脉冲电流频率呈较好的正相关关系,而肌张力随刺激电流强度的增加似乎并不明显.

| Abstract: | This experimental study was designed to unravel the relationship between muscle tension and its electrophysiological property. The experiments on repetitive pulse stimulus in different current intensity to rabbit's motor nerve were performed in different pulse frequency by electromyography which applied electrical pulses and excited the tibial nerve, and by Instron 5544 machine which measured muscle tensions. The experimental data revealed that the tension force varied with the stimulus frequency in a quasi-parabolic relation, while it seemingly increased little with the stimulus intensity. |
