Utilization studies of low quality woods produced by China

本研究项目的目的是开展中国木材利用的基础研究，通过引进日本木材工程和木材加工技术，制定利用中国生产的低质量木材并将其推广到新的应用领域的基本计划。为此，岛根大学的6名成员和东北林业大学的3名成员分别前往中国和日本，就该项目进行了讨论，并考察了中日两国互校的研究所和一些民营企业的工厂。此外，我们还研究了利用中国生产的低质量木材的以下研究主题：(1)利用二维快速傅里叶变换对木材细胞进行图像处理分析；(2)木材的物理性质；(3)开发天然和合成纤维增强的高强度胶合板；(4)木材和木材材料的宜居性调查；(5)用木材食料进行水处理；(6)用电冠排放处理改善木材的胶合性。本研究项目的部分成果已在两本书和两篇摘要中发表，其余成果将在期刊上发表。

The purpose of this research project is to develop a fundamental research on wood utilization in China, and to direct a basic plan of using low quality woods produced by China and spread them to new applicable fields, by introducing techniques of wood engineering and wood machining in Japan into China. For these purposes, six members in Shimane University had been to China, and three members in Northeast Forestry University had been to Japan, to discuss on this project and to inspect research institutes of mutual university and some factories of private enterprises in Japan and China. Furthermore, we investigated on following research themes for utilization of low quality woods produced by China : (1) analysis of wood cells by image processing using two-dimensional fast fourier transforms, (2) physical properties of woods, (3) development of high strength plywoods reinforced by natural and synthetic fibers, (4) survey of livability with woods and wood materials, (5) water treatment with wood vinegars, (6) improvement of gluability of woods by corona dischrge treatment. Some of the results of this research project have been published in two books and two abstracts, and the others will be published in journals.
