The results show that during bioleaching the chalcocite decom posed by two stages, the stageⅠis controlled by the concentration of ferric, with the increase of ferric concentration the oxidation rate of chalcocite is enhanced. The rate of stageⅡis slower than that of the stageⅠand it acts as the confining stage, and the concentration ratio of ferric to ferrous influences the oxidation rate at this stage.

计算与实验结果表明：模型仿真结果与实际结果较符合；堆浸过程次生硫化铜矿的氧化分为2个阶段，其中，辉铜矿反应步骤Ⅰ受溶液Fe3+浓度控制，随着Fe3+浓度增加，反应速率加快；反应步骤Ⅱ较反应步骤Ⅰ慢，为浸出反应的限制性步骤， Fe3+与Fe2+的浓度比是影响该反应步骤的关键因素。

In leaves,the concentration of Cd and Cu been up to 168.6μg·g~(-1) and 30.1μg·g~(-1),while in roots, they have been to 610.9μg·g~(-1) and 384.6μg·g~(-1).In these concentration compages,the leaves could accumulate Cd at a high rate,Cd50mg·g~(-1) Cu50 mg·g~(-1),Cd80mg·g~(-1) Cu30 mg·g~(-1),Cd80mg·g~(-1) Cu50 mg·g~(-1).At the concentration of Cd50mg·g~(-1) Cu50 mg·g~(-1), Iris pseudacorus L. could accumulate Cd and Cu at a high rate:inleaves,Cd82.908μg·g~(-1), Cu30.722μg·g~(-1),in roots, Cd266.181μg·g~(-1), Cu395.83μg·g~(-1),and at this concentration the plant could grow well, the dry weight of leaves and roots of it were 64.3% and 81.1% of the concentration compage Cd0mg·g~(-1 Cu50 mg·g~(-1)s.

研究表明，①黄菖蒲对Cd、Cu均有较强的吸收积累能力，其中对Cd的吸收积累能力相对大于Cu：地上部Cd、Cu含量最高分别达168.6μg·g~(-1)和30.1μg·g~(-1)，根部Cd、Cu含量最高分别达610.9μg·g~(-1)和384.6μg·g~(-1)；黄菖蒲地上部分Cd积累量均随处理浓度的升高而增加，特别在处理Cd50mg·g~(-1) Cu50mg·g~(-1)组合胁迫下，黄菖蒲对Cd、Cu的积累量为：叶的Cd含量为82.908μg·g~(-1)，Cu为30.722μg·g~(-1)；根的Cd含量为266.181μg·g~(-1)，Cu395.83μg·g~(-1)，且生长良好，叶和根的干重分别为处理Cd0mg·g~(-1) Cu50 mg·g~(-1)的64.3％和81.1％。

The recoery rate was calculated as follows;(JOA score at follow up_preoperatie JOA score)/(17 _ preoperatie JOA score) _ 100,15 and the surgical outcomes were classified into four grades based on the calculated recoery rate; excellent: recoery rate 75% or higher, good: 50–75%, fair: 25–50%, and poor: lower than 25%. Ealuation was made on radiographic findings, including the range of motion and the jaw diameter (a measured line from the posteroinferior corner of the ertebral body to the anterior aspect of the subjacent lamina) at the adjacent leels in group A and the affected leels in group B and the spinal canal diameter at the C4 leel in both groups. The C4 leel was chosen for this measurement, because the spinal canal is usually narrowest at this leel.

恢复率如下计算；（随访JOA评分-术前JOA评分）/（17-术前JOA评分）*10015，按计算的恢复率将手术结果分4级；优：恢复率75%或更高，良：50-70%，中：25-50%，差：低于25%。X线片结果评价，包括活动范围和颌直径（从椎体下后角到下邻椎板前方的测量线）在A组相邻水平与B组受影响水平及两组C4水平椎管直径。C4作为该侧量的选择是因为通常在此平面椎管最为狭窄。
