摘 要: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005水平下,除年轮宽度、差异干缩外,皆显著。The paper inverstigated the effect of intermittent flood upon the wood physical and mechanical properties of Taxodium ascendens. The results are as follows: Annual rings width、 latewood percentage、 shrinkang、 basic specific gravity and main mechanical properties of Taxodium ascendens wood under intermittent flood are smaller than those of wood without intermittent flood, but shrinkage differences of wood is bigger than that. The T test valves indicated that there no significant differences between wood under intermittent flood and without intermittent flood in annual rings width and shrinkage differences, there are significant variances in other physical and mechanical properties.
