我们对超低倍观察切片的制作技术进行了探索,并获得了初步成效,现介绍如下。用常规处理的电镜组织包埋块,以瑞典LKB—Ⅲ型超薄切片机,常规玻璃刀制作大切片。用日立H-300型透射电镜进行广视超低倍观察。此法既能充分发挥电镜的分辨作用,又能观察多量细胞,可以弥补光镜与电镜之间过分悬殊的倍率差别。从而在形态学分析时能够进行由低到高、由简至繁等一系列过渡观 We explored the production technology of ultra-low magnification sections and achieved initial results, which are presented below. Electron microscopy with conventional embedding blocks, with the Swedish LKB-Ⅲ ultra-thin slicer, conventional glass knife making large slices. With Hitachi H-300 transmission electron microscopy ultra-low magnification observation. This method can give full play to the role of electron microscopy, but also observe a large number of cells, you can make up for light microscope and electron microscope over disparity magnification differences. Thus morphological analysis can be carried out from low to high, from simple to complex and a series of transitional view
