以神经和肌细胞膜为代表的兴奋膜(excitable membran(?))的特性和由此而产生的生物电现象,是体内最基本的生理过程之一,在近代生理学的发展中占有重要位置。1902年Bernstein提出膜学说,是上世纪中、后期对两栖类神经和肌肉电活动进行长期研究的总结,它从细胞表面膜的水平说明生物电现象,为理解生物电的产生机理开创了正确的途径。但以 The excitable membran (represented by nerve and muscle cell membrane) characteristics and the resulting bioelectric phenomenon, is one of the most basic physiological processes in the body, occupies an important position in the development of modern physiology. In 1902, Bernstein put forward the film theory, which is a summary of the long-term research on amphibian nerve and muscle electrical activity in the middle and late of the last century. It explains bioelectricity from the level of cell surface membrane and opens up a correct way. But to
