| 摘要: |
| 目的：利用模数转换技术进行骨骼肌肌浆网确定时间内功能形态变化的研究。方法：采用双向红外线探测器、模数转换卡、计算机和Reichert Jung KF-80快速冷冻仪组成计算机控制的电刺激超低温快速冷冻固定系统，在蟾蜍骨骼肌兴奋-收缩偶联变化的瞬间，实时测定功能变化经历的精确时间。结果：测量得到骨骼肌肌浆网功能变化的0.8，5.6，8.4 ms时间间隔，并同步获得骨骼肌肌浆网的超微结构形态图像。结论：计算机模数转换技术控制电刺激超低温快速固定技术有效地实现了生物学中功能形态瞬时变化的同步研究。 |

| Abstract: |
| Objective: To use analogtodigital conversion technique to mensurate the time interval in skeletal muscle during excitation-contraction coupling. Methods: Two way infrared detectors, analogtodigital conversion card, Rechert Jung KF-80 quick freezing fixation were employed in this test. Results: The time internal of 0.8,5.6,8.4 ms during the skeletal muscle function change was measured, and the morphological images were synchronously obtained. Conclusion: Analogtodigital conversion technique provides the methodology for the function-morphological study |
| Key words: analogtodigital conversion skeletal muscle functional morphology |
