摘要：
对毛竹圆竹的人工干燥特性进行了研究,研究结果表明:圆竹在干燥过程中重量变化主要发生在干燥前期,而后重量变化很小,这是圆竹脱水的主要阶段；干燥初期竹材在高含水率状态下,水分蒸发在细胞壁和细胞腔同时发生,使竹壁在干燥初期就开始发生收缩,随着竹壁厚度增加,其收缩率相应增加；在干燥前期,在高含水率状态下,薄壁圆竹比厚壁圆竹有更快的干燥速度；在后续干燥阶段,不同壁厚的圆竹脱水率相差不大,圆竹干燥终点的脱水率与竹壁厚度和长度无相关性,圆竹在干燥过程中,水分蒸发不仅发生在圆竹的横切面上,也发生在其内、外壁上.%Artificial drying properties of Moso bamboo were studied. The results showed that the weight loss of round bamboo occurred mainly at earlier stage, the main dehydration period, thereafter, the weight changed little. At earlier stage of drying, water content of round bamboo was high, water evaporated from cell wall and lumen of the bamboo at the same time so that bamboo wall started to shrink, and shrink ratio increased with the increase of bamboo wall thickness, thin-wall round bamboo dried faster than thick-wall one. In the follow-up drying stages, the dehydration ratio of round bamboo with different wall-thickness had little difference, and at the end dehydration ratio was not correlated with wall-thickness and length of round bamboo. The evaporation occurred not only at the cross section, but also on inner and outer faces of round bamboo.
