以东北色木为试材 ,对其径向、弦向、非标准向压缩木的干缩性测试结果表明 :不论那个方向压缩 ,压缩木压缩方向的干缩率明显高于非压缩方向 ;压缩木压缩方向上的干缩率 ,径向压缩木的干缩率最小 ,且径向压缩木 ,径向、弦向干缩系数之比最小 ;压缩木压缩方向的垂直方向上的干缩率 ,弦向压缩最小 ,径向压缩最大 ,非标准向居中。
The results of tests on shrinkage of radial wood, chord wood and non-standard wood show that no matter in that direction, the shrinkage rate of compression wood is obviously higher than that of non-compression wood. Compression The shrinkage rate in wood compression direction and the shrinkage rate of radial compressed wood are the smallest, and the ratio of radial compressive wood, radial and chord shrinkage coefficient is the smallest; the shrinkage in the vertical direction of compressed wood compressive direction, The smallest chord to the compression, the largest radial compression, non-standard to the center.
