摘　　要：对经过水热软化处理和顺纹压缩后榆木试件的单向和"S"形弯曲性能进行研究,结果表明:成熟材的单向和"S"形弯曲性能好于幼龄材;弦向的单向和"S"形弯曲性能好于径向;顺纹压缩后"S"形弯曲性能好于相应的单向;幼龄材、径向和"S"形弯曲的变异性相对较小。Single direction and ＂S＂ type bending performance of hydrothermal-treated elm after longitudinal compression is analyzed. The result shows that the single direction and ＂S＂ type bending performance of mature wood is superior to that of juvenile wood; the single direction and ＂S＂ type bending performance in the tangential direction is superior to that in the radial direction; the＂S＂ type bending performance after longitudinal compression is superior to corresponding single direction bending performance; the variability of juvenile wood in radial direction, and ＂S＂ type bending performance s relatively small.
