| 摘 要： | 分析了膜电位的测量原理,设计了用电位差计测量膜电位的实验,生物膜采用自制的蛋膜.实验表明:当蛋膜两侧氯化钾溶液浓度的比值增大时,膜电位随之增大,膜电位的大小与膜两侧氯化钾溶液浓度比值的对数线性相关,但两者并不满足能斯特方程.

| Abstract: | It was analysed the principle of measuring membrane potential and designed an experiment to measure membrane potential by potential difference meter.The membrane was made of eggshell membrane.The experiment showed that the membrane potential increased when the ratio of the concentration of the potassium chloride solution on both sides increased,and there was a linear relation between the membrane potential and the logarithm of this ratio,but they did not follow the Nernst equation. |

| Keywords: | potential difference meter measure membrane potential Nernst equation |
