摘要
林木定向培育和木材资源的优化利用,都需要对大量木材样本的性质进行快速测试。然而,传统的测试方法成本高、效率低,不能满足生产和科研的需要。近红外光谱技术是一种新的无损评价方法,能够迅速、准确地对木材试样的性质进行预测。文中主要介绍了近红外分析技术的基本原理、特点以及在预测木材化学组成、物理力学性质、解剖性质等方面的研究进展。
For forest definite cultivating and optimal utilization of wood resources, many samples need testing. The cost of traditional test method is high and the efficiency is low, so new method would be needed to find. Near infrared （NIR） spectroscopy is an advanced analysis tool for nondestructive evaluation, which can be quickly, accurately to estimate wood properties. This paper introduces the basic theories and main characteristic of NIR analysis, and then reviews the advances in the research of the wood chemistry, physics and mechanics, anatomical properties using NIR.
