电子显微镜是利用电子束通过电子透镜几次放大达到高分辨率,可以观察到只有几个埃大小的物质(1毫米=10,000,000埃)。这样就使人们一跃而达到超微观世界了。在医学领域中,人们利用这一工具,加上不断更新的技术、方法和一些辅助设备,直接认识病原体或病原体作用于机体后出现的病变;提高了对疾病发生和发展的认识,促进了生理学、生物化学、病理学、病毒学等基础医学及临床 Electron microscopy uses electron beams to achieve high resolution through several magnifications of the electron lens. It is possible to observe only a few angstroms of material (1 millimeter = 10,000,000 angstroms). This will enable people to leap to the ultra-microscopic world. In the medical field, people have used this tool, coupled with constantly updated techniques, methods, and auxiliary equipment, to directly recognize the pathological changes that occur after pathogens or pathogens act on the body; to increase awareness of the occurrence and development of diseases, and to promote physiology. , biochemistry, pathology, virology, and other basic medicine and clinical
