研究了使用 DRIFT（漫反射红外傅里叶变换）光谱结合多元分析方法（PLS（潜在结构投影）、回归）来预测樟子松 (Pinus sylvestris) 干材中主要有机成分（纤维素、葡甘聚糖、木聚糖、木质素和提取物）分布的可行性。进行 PLS 校准是为了在传统（“基于湿化学”）木材分析的数据集与相应木材样品的 DRIFT 光谱之间建立数学相关性。基于这种方法，显示了干木基质内主要有机成分含量变化的不同表面图。
The feasibility of using DRIFT (diffuse reflectance infrared Fourier transform) spectroscopy combined with a multivariate analysis method (a PLS (projection to latent structures), regression) for predicting the distribution of the main organic constituents (cellulose, glucomannan, xylan, lignin, and extractives) within the Scots pine (Pinus sylvestris) stemwood was examined. PLS calibrations were carried out to establish a mathematical correlation between the data sets of conventional (“wet-chemistry-based”) wood analysis and the DRIFT spectra of the corresponding wood samples. Based on this approach, different surface maps on variations in the content of the main organic constituents within the stemwood matrix were shown.
