查询词典 hull

Bamboo variation ofmicrodensity of all age-degree and all height bamboo from bamboo green tobamboo yellow as follows:The downtrend ladder of microdensity the firststage from bamboo green to bamboo yellow is relatively large,normally at theplace 0.35 from bamboo hull(the thickness of from bamboo hull to bambooyellow is 1)micro-density downtrend ladder begin to get smaller,variancerange of microdensity is smaller.When reaching near bamboo yellow area,microdensity reaches its minimum value,and when reaching bamboo yellowsection density increase rapidly,the minimum density of bamboo is only 50% orless of maximum density.Bamboo yellow is comprised of stone cells whichhave thick cell wall,so its density is high,normally 50% to 100% more thanminimum density.Bamboo yellow′s lay thickness is thin,normally the samethickness for all age-degree and all height bamboo,about 0.8mm.From 1 age-degree bamboo to 2 age-degree bamboo during growth,the increase of averagedensity is mainly in bamboo pulp section,from 3 age-degree bamboo to 4 age-degree bamboo,the decrease of average density is mainly decrease in the pulpsection.Same age,same height,the less the density ladder of bamboo radialthickness,the higher the mechanical strength.

所有年龄所有高度的竹材微密度从竹青到竹黄对材性变异规律如下：从竹青到竹黄开始下降梯度较大，一般到相对竹皮距离0.35左右处(整个竹壁厚度为1)，竹材微密度下降梯度减小，微密度的变化范围变小，到近竹黄处，微密度达最小值，而后到竹黄部位密度大幅上升，竹材最小密度一般只有最大密度的50％或更低，竹黄由厚壁的石细胞组成，所以密度较大，一般比最小密度增大约50％-100％，厚度较薄，不同年龄不同高度竹材的竹黄厚度相差无几，约在0.8mm左右；竹材从1度竹到2度竹生长过程中，平均密度的增长主要发生在竹肉部分，从3度竹到4度竹生长过程中，平均密度的下降主要发生在竹肉部分，同一年龄同一高度，竹壁厚径向的密度梯度越小，力学强度越高，随着年龄的增大，密度梯度越来越小(1度竹除外)，随着高度增加，密度梯度越来越大。

以去除盐湖卤水中COD和浊度为目的，选用煤质活性炭、果壳活性炭、木质活性炭3种不同活性炭进行净化除杂的工艺研究，结果表明：果壳活性炭对COD和浊度的去除率最低，加入量最大，不宜选用；木质活性炭在低温下(≤20℃)脱除COD效果较好，在常温下(28~45℃)去除COD和浊度的效率明显低于煤质活性炭；在震荡速度、吸附时间及吸附剂加入量均相同的情况下，煤质活性炭脱色除杂效果明显优于其余两种活性炭，在盐湖卤水的脱色净化工程中应优先选用。
