本文就落叶松木材流体渗透性及其定向控制的问题作了研究。试验包括木材气体渗透性、液体渗透性以及吸水动力学等方面,此外还进行了木材显微化学试验和显微气体渗透性试验。研究表明,落叶松木材(心材)经溶剂抽提处理后,其渗透性显著地得到改善。

Results of the experiments are given as follows:1. Variation of the fluid permeability in wood is extremly large. Even within the same tree species the fluid permeabilities in some wood samples may be 1—1000 times higher than those of the others. 2. The permeabilities in both coniferous and broadleaved species heartwoods are much lower than those in sapwoods. The fluid permeabilities in early and late wood of an annual ring vary with tree species. Such as Pinus yunnanensis, the fluid permeability in early wood...

Results of the experiments are given as follows:1. Variation of the fluid permeability in wood is extremly large. Even within the same tree species the fluid permeabilities in some wood samples may be 1—1000 times higher than those of the others. 2. The permeabilities in both coniferous and broadleaved species heartwoods are much lower than those in sapwoods. The fluid permeabilities in early and late wood of an annual ring vary with tree species. Such as Pinus yunnanensis, the fluid permeability in early wood is higher than that in late wood, but on the contrary in Pinus sylvestris var. monglica. As for Pinus massoniana it has the same permeability both in early and late wood. 3. The fluid permeabilities in wood of both coniferous and broadleaved tree species are much higher in longtudinal direction than those in cross direction. The latter varies in tangential and radial direction depending on coniferous or broadleaved tree species. The fluid permeability of coniferous wood in radial direction is a little bit higher than that in tangential direction, while in broadleaved wood it is a little bit lower in radial direction than in tangential one. 4. The fluid permeability in wood has no relation with its density. 5. The gas permeability in wood does not relate to the kind of gases. For example, the permeability of air, oxygen or nitrogen in wood is almost same, but it will be decreased as the wood moisture content increases, and will be become greater as the gas pressure increases and the pressure time puts off.

本文采用气流法和液流法,研究了17个树种的木材流体渗透性与影响它的因子,探明了木材渗透性的一些基本规律,为木材制浆、蒸煮、干燥、防腐、改性等制订合理工艺和提高处理质量提供了科学依据。

The fluid permeability of wood is studied by the method of energy spectrum analysis. Taking AgNO_3 solution as permeable medium and Ag~+ as tracing ion, the relative distribution of Ag~+ in micro-structure of wood was observed, using scanning electron microscope with the spectrometer. A number of laws of wood fluid permeability are obtained by caculating relative content of Ag~+ using spectrometer. It provides & new method for studying fluid permeability of wood.

本文采用能谱分析法研究木材的流体渗透性,即把AgNO_3水溶液作为渗透介质,Ag~+为示踪离子,利用附有能谱仪的扫描电镜,观察木材微观构造图上Ag~+的相对分布,通过能谱仪测算Ag~+的相对含量,初步研究了木材流体渗透性的一些规律。为研究木材流体渗透性提供了新的方法。
