The experimental results indicates that the optimum pH range was 1.60~2.20, and the optimum H2O2 concentration was 10.0 mmol/L. The degradation ratio increased with the increasing concentration of ammonium ferric oxalate in the range from 0.1 to 1.0 mmol/L, but no significant increase in degradation ratio was observed when the concentration was above 1.0 mmol/L. When the concentration of fuchsin basic increased, the degradation ratio dropped, while the concentration of degraded fuchsin basic rised. When the concentration of fuchsin basic was low, the degradation followed first-order kinetics, but when it was high, the degradation could be fitted by zero-order kinetics. The absorbtion of fuchsin basic at 543 nm disappeared quickly, while the absorbtion of intermediates formed during the course of fuchsin basic dagradation at 298 nm vanished slowly.

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。
