华北农大裘维蕃教授一九七五年四月三日在河北省满城县小麦病毒病报告会上的讲话(根据记录摘要整理,未经本人审阅。)一、病毒病的基本知识病毒是可以看见的,但用眼睛看不到,因为它太小了。一般显微镜只能放大三千倍,它可以看到微生物,看到细菌、真菌,而病毒比这些东西小得多,显微镜也不能看到它。另外一种显微镜,叫电子显微镜,它可以放大二十万倍,所以用电子显微镜可以看到病毒。

First, the basic knowledge of the virus disease virus is visible But I can not see with my eyes because it is too small. The general microscope can only magnify three thousand times, it can see the microorganisms, see bacteria, fungi, and the virus is much smaller than these things, the microscope can not see it. Another microscope, called an electron microscope, can magnify two hundred thousand times so the virus can be seen with an electron microscope.
