1780年,意大利科学家伽伐尼在做青蛙解剖时,拿着不同的金属器械,无意中同时碰到青蛙的大腿,青蛙腿部的肌肉立刻抽搐了一下。伽伐尼认为,这种现象是因为动物躯体内部有“生物电”造成的。接下来意大利科学家伏特多次重复了这个实验,发现伽伐尼的解释是错误的,伏特的新发现是青蛙肌肉中的液体让金属 In 1780, the Italian scientist Galvani was doing a frog anatomy, holding different metal instruments, inadvertently hit the thighs of the frog at the same time, the frog leg muscles immediately twitched. Galvani believes this phenomenon is caused by the “bioelectricity” inside the animal’s body. Next Italian scientist V repeated this experiment for several times and found that Galvani’s explanation was wrong. The new discovery by Volta was that the liquid in the frog’s muscle made the metal
