| 摘 要： | 采用“先离体法”和“后离体法”两种方法制备蛙坐骨神经-腓肠肌标本，通过实验记录，对标本的收缩机能进行了比较．结果表明后离体法制备的标本单收缩幅度高，潜伏期和舒张期时程缩短，并对其原因进行了分析与讨论．

| Abstract: | Nerve-muscle specimens of frogs were prepared by two distinctmethods: First detachment of specimen from the body, and last detachemnt. According to the record of experiments, contracting functions of specimens prepared by the two ways were compared. It was found that single muscle twitch of “Last detachment” specimens showed a higher average of contraction range but a shorter average of time in latent and relaxation periods than that of “First detachment” ones. Some relative reasons were analysed and discussed. |
