利用肉眼和放大镜来鉴别木材,即根据木材相视构造或宏(巨)观构造的特征来鉴别木材,对生产、使用和研究木材者都具有重要的意义。木材的粗视构造有那些特征,如何正确解释和应用这些特征,这是本文的目的。为使人们容易理解,除文字叙述外,并附以低倍显微照片(直径放大10倍)。本文所用照片,除大部分为10倍或11倍的显微照片外,另有两类不同来源:一系利用反射投影描绘器(反光镜)将显微镜上的切片直接反射到放大纸上,结果得到负相照片;
The use of the naked eye and a magnifying glass to identify wood, that is, the identification of wood according to the features of wood facies or macroscopic structures, is of great importance to those who produce, use and study wood. It is the purpose of this article to describe the features of the rough structure of wood and how to correctly interpret and apply these features. In order to make it easy to understand, in addition to the text description, accompanied by low magnification micrographs (diameter 10 times larger). In addition to most of the 10x or 11x photomicrographs, there are two different sources of photographs used in this article: a series of reflectance projection imagers (reflectors) that mirror the sections of the microscope directly onto the magnified paper, and the result Get negative photos;
