查询词典 red fir

The infra red spectra of specimens show that there are evident changes of waves at the wavelength of 1743, 1660 and 1605cm-1 which are attributed to the change of C=O in wood. So it is clear that at least hemicellulose, even lignin in wood cell chemically changes during heat treatment of compressed wood of China fir.

红外吸收光谱表明，在热处理过程中波数在1743，1660和1605cm-1附近的羰基峰的变化趋势最为明显，说明在热处理固定杉木压缩木材的过程中，至少半纤维素，甚至木素发生了化学变化

He finally settled on a post-and-beam design (the structural weight of the building is up and down so it doesn't need internal walls) in honey-coloured Douglas Fir with red cedar cladding.

最终，他定下一种梁柱式设计（这种房屋结构是上下承重，所以不需要内墙），并采用蜜黄色花旗松，外墙板为铅笔柏覆层。

Production of the European pine, Finland wood, southern pine, Canadian red cedar, fir, pine, Russian pine and various sub-Catalpol wood line anti-corrosion products, carbonized wood, fire-retardant material had been used for residential quarters, villas, parks, squares, etc..

The main species of timber we are dealing with are Red pine, Spruce, Fir, Larch, Birch, Cedar, etc.

It is shown that it is difficulty to differentiate each vegetation type among sub-tropical evergreen forest, sub-tropical coniferous forest and sub-tropical deciduous forest because of the mixture of their tree spectra. According to the reflection index in the wavelengths of 750 nm to 1 100 nm, the tree species can be divided into 4 groups with descend in reflectivity. Each tree specie can be differentiated from each other according to its slope of the spectrum curve and its reflection index in the wavelengths of 770 nm to 1 010 nm for each forest vegetation type. The unique first order derivative feature can be used to identify litsea, alder, fir, red birch, southwest birch, large schima confertiflora, taiwania flousian and small leaf schima confertiflora.

研究表明：亚热带常绿阔叶林、亚热带针叶林和亚热带落叶阔叶林等植被类型，因其树种间光谱特征混淆严重，而难以彼此区分；根据其反射率在750~1 100 nm范围上的差异，可将其归为4类；就各植被类型而言，其树种间在光谱曲线坡度，以及在770~1 010 nm范围上具有显著差异，可据此将其区分；木姜子、桤木、杉木、红桦、大叶木荷、秃杉和小叶木荷等因具有独特的光谱一阶导数特征，据此可以识别提取。
