【摘要】 本文介绍了应用霍耳效应原理、借助特殊的胃探头固定装置,记录家兔胃运动的方法。 在胃探头固定装置上安装引导电极,可同时记录胃电变化。本记录方法根据磁块移动距离与电压变化的函数关系,可由测得的电压变化数值,计算出胃平滑肌收缩时移动的距离,并能较好的消除呼吸波,具有较强的抗干扰能力。更多还原

【Abstract】 A method based on Heuer Answer Principle for recording the stomach move-ment in rabbits in chronic experiment was described. If a pair of electrodes areattached to the stomach probe fixed to the wall of stomach, electric activity of whichcan be registered simultaneously. According to the relation between the distance of the magnet displacementand the output of the voltage from the stomach probe, the amplitude of the contrac-tion of the stomach smooth muscle can be estimated. With this method of record-ing the stomach movement, the interference of respiration and antifacts due tobody movement can be eliminated.更多还原
