第一张植物病毒的电子显微镜照片 人类对病毒的了解晚于其他微生物,其主要原因之一是受科学技术发展水平的限制。早在前一世纪末期,就已证实了病毒的病原性,但很久无法看到它的形状。因此许多人利用各种物理学方法推测病毒的形状及其大小,例如利用各种不同孔径的滤器进行测定,也有将含有病毒的液体在偏振光下表现双折射的现象,如1933年曾使用这一方法证明了
The first picture of a plant virus electron microscopy human understanding of the virus later than other microorganisms, one of the main reasons is limited by the level of development of science and technology. As early as the end of the previous century, the virus’s pathogenicity has been confirmed, but it has not been able to see its shape for a long time. Many people therefore use a variety of physical methods to infer the shape and size of a virus, for example, using filters of various pore sizes, as well as birefringence of liquids that contain viruses under polarized light, as used in 1933 A method proved
