(一)新电子显微镜普通的显微镜只能将实物放大到2,000—2,500倍,而用电子注来代替光线的电子显微镜,就能放大到十万倍之多。这种显微镜的设备很是庞大,其重量约有两吨。但是其中光学部分装置仅不过数千克,同时也很容易缩小放大为了使实验室更方便的掌握这种研究工具,苏联现在创造了一种和小型写字台一般大小的轻电子显微镜,只用一个人就能很容易地推动它。轻电子显微镜能将实物放大五万倍。有24×36毫米大小的镜头可以用来摄影,利用这种摄影机可以连续摄影二十五次。
(A) The new electron microscope The ordinary microscope can only enlarge the physical object to 2,000-2,500 times, and the electron microscope that uses electron injection instead of light can be enlarged to 100,000 times. The equipment of this microscope is very large, and its weight is about two tons. However, the optical part of the device is only a few kilograms, but it is also very easy to reduce the magnification. In order to make the laboratory more convenient to grasp this research tool, the Soviet Union has now created a light electron microscope with the size of a small desk, using only one person. It can be easily promoted. The light electron microscope can magnify the object 50,000 times. A 24 x 36 mm lens can be used for photography. With this camera, it can be shot 25 times in succession.
