国内的木材超微构造研究在80年代初开始,但由于电镜用样品的制备技术比较复杂,往往得不到理想的研究结果。为此,把我们的电镜制样技术经验介绍如下。用透射电镜研究木材超微构造时,通常用金属投影复型法和超薄切片法以制备观察用木材样品。前者可用来研究木材表面的超微构造,后者用来研究木材的细胞壁及其雕纹的剖面。两种方法结合起来才能得到对木材超微构造的完美了解。 Domestic research on the ultrastructure of wood started in the early 1980s, but due to the complexity of the preparation technology of samples for electron microscopy, the ideal research results are often not obtained. To this end, the technical experience of our electron microscopy sample described below. TEM study of the ultrastructure of wood, usually by metal projection complex method and ultra-thin section method for the preparation of observation timber samples. The former can be used to study the ultrastructure of wood surface, which is used to study the wood cell wall and its glyph profile. The two methods combine to get a perfect understanding of the ultrastructure of wood.
