Carbohydrates, formed of about 100 cellulose chains, are embedded in a matrix of hemicelluloses and lignin. Pores in the matrix are small and enable transfer of water, salts, and small organic molecules only. Although the hemicelluloses are at least partly water soluble, they cannot diffuse out of the cell wall d作者: 流利圓滑 時(shí)間: 2025-3-22 01:25 作者: babble 時(shí)間: 2025-3-22 05:11 作者: 亞麻制品 時(shí)間: 2025-3-22 12:13

Analysis of Inorganic Constituents, constituents of the wood material and their total concentrations (measured as ash) rarely exceed the 1% level. The inorganic ions are normally taken up by the living tree through the roots from the soil. The mineral elements play an important role in the growing process of the tree.

Analysis of Inorganic Constituents,have been reported in the literature (Young and Guinn 1966; Koch 1972, 1985, 1996; Wardell and Hart 1973). Table 10.1 shows the distribution of the elements in different concentration ranges in the trunk wood of a pine tree from southwestern Finland. The concentrations were determined by inductively coupled plasma mass spectrometry (ICP-MS).作者: 同謀 時(shí)間: 2025-3-23 19:06
