Through comprehensive comparison,during the growth from 1 age-degree bamboo to 2 age-degree bamboo,density, mechanical strength(except maximum tensile strength etc.),fraction of bundle sheath,cell wall ratio,crystallinity,cellulose content and lignin content increase rate are the greatest.3age-degree bamboo has higher strength,strength and gravity ratio andcrystallinity are the biggest,fraction of parenchyma is small and insect-resistant.2 degree bamboo has the greatest mechanical strength,but its strength andgravity ratio is not the highest and its crystallinity is lower than 3 age-degreebamboo due to its greatest fraction of parenchyma,loss tangent value is thebiggest.Its creep character is not good and is easily eaten by moth.

通过综合比较，竹材从1度竹到2度竹生长过程中，密度、力学强度、纤维束比量、胞壁率、结晶度、纤维素含量、木质素含量等指标增加幅度是最大的。3度竹强度较高，强重比、结晶度最高，薄壁组织含量较小，相对抗虫蛀，材质最好，适合材用。4度竹结晶度下降引起强度的下降，但薄壁组织组织比量最小，相对最抗虫蛀。2度竹力学强度最大，但是强重比并不是最大，结晶度比3度竹低，由于薄壁组织组织比量最大，内耗值最大，蠕变性能较差，同时相对易遭虫蛀。

The physicochemical properties of cx - 2 correspond to cytodex - 3 mc produced by pharmacia , including of color , loss of drying , area , density , size , soakage , dilation , stability , size distribution , mechanical strength , surface structure , etc ., but its cost of manufacture is lower than cytodex - 3 s
