本文研究了间歇性淹水对池杉木材物理力学性质的影响。结果表明：间歇性淹水使池杉木材的年轮宽度、晚材率、干缩率、基本密度、顺纹抗压强度、抗弯强度、抗弯弹性模量、冲击韧性下降；使差异干缩增加。经Ｔ－检验，在００５水平下，除年轮宽度、差异干缩外，皆显著。 This paper studies the effects of intermittent flooding on the physical and mechanical properties of Ipomoea Japanese fir wood. The results showed that intermittent flooding decreased the annual ring width, latewood rate, dry shrinkage rate, basic density, compressive strength, flexural strength, flexural modulus and impact toughness of Ipomoea Pine, Shrink increase. T-test, at 005 level, except for the ring width, differences in shrinkage, are significant.
