目前,光学显微镜还是医学上一种不可缺少的工具。应该怎样通过显微镜才能看清楚所需要观察物体的细节?首先要有适当的分辨本领,以保证被观察物体微小细节的象不重迭;其次要有适当的放大率,以保证被观察物体微小细节的象在眼睛中的视角大于1分,二者缺一不可。选用过大或过小的分辨本领和放大率所看到的象都是不够理想的。所谓显微镜的分辨本领,指的是它所能分辨物体两点之间最短的距离,这个距离越小,它的分辨本领就越高;反之,就越低。定量之间的关系可由下列公式描述:
At present, optical microscope is an indispensable tool in medicine. How to look through the microscope to see the details of the need to observe the object? First of all, there must be appropriate resolution skills to ensure that the observed objects are not overlapping details of small details; followed by the appropriate magnification to ensure that the observed object is small details The image of the eyes in the eyes of more than 1 point, both indispensable. The choice of too large or too small resolution and magnification can see the image is not ideal. The so-called resolution of the microscope means that it can distinguish the shortest distance between two points of an object. The smaller this distance is, the higher its resolving ability is. On the contrary, the lower it is. The relationship between quantification can be described by the following formula:
