The results showed that the amorphous iron oxide has highly catalytic activity. The intermediate products are pyrocatechin, hydroquinone, benzoquinone and low-grade fatty acid. The mechanism of catalyst oxidation is assumed that the free radical OH attacks benzene cycle at the adjacent position and para-position of OH on phenol so that the benzene cycle is opened and low-grade fatty acid is produced and transformed into CO2 and H2O.
结果表明,非晶铁氧化物催化剂在催化氧化降解苯酚时具有较高的催化活性,苯酚降解的中间产物有:对苯二酚、邻苯二酚、苯醌和低级脂肪酸,其降解机理是羟基自由基攻击苯环上OH的部位或对位而使苯环开环,生成低级脂肪酸,并最终转化成二氧化碳和水,从而使苯酚得以降解。

In order to study the numerical method to solve the viscous incompressible flow with free surface, the 3-D mathematical model for steady and unsteady hydrodynamic problem had been established and closed by k-εbuoyant turbulence model. The algebraic coordinate transformation method was used to fit the free surface, the Runge-Kutta method of three step and second precision was devised to simulate the time step. A high precision up-winding compact scheme was studied for the convection term, and the generalized conjugate residual method was set to solve the Poisson equation.
为了研究粘性不可压缩三维问题的数值求解方法,本文从基本的Navier-Stokes方程出发,采用代数拟合方法处理自由表面,用三级二阶Runge-Kutta方法对时间步进过程进行了模拟,并且对对流项的高精度迎风格式进行了研究,给出了求解压力Poisson方程的广义共轭剩余法,从而建立了能够模拟有自由表面的粘性不可压缩问题的定常、非定常三维水动力学模型,并采用k—ε浮湍流模型对其进行封闭。

The results indicated that the accumulation of Mn in the cell wall (accumulation rate as high as 36.34%) and the vacuole of the leaves (accumulation rate as high as 65.64%) might be one of the mechanisms of tolerance and hyperaccumulation of Polygonum hydropiper to Mn. Most Mn in leaves were the speciation of H2O-solubility organic salts or manganese oxalates. The content of chlorophyll a did not change under different Mn concentration treatments except that its content decreased remarkably when Mn concentration was 8000μmol/L in solutions. The membranes were not banned by Mn when its concentration was less than 5000μmol/L in solutions; Under different Mn concentrations of Mn, the content of their soluble proteins of leaves had changed at some stage. The activity of SOD and POD were gradually improved with the increasing of Mn concentration, which could eliminate activated oxygen free radical, This might be the other physiological mechanism of tolerance and hyperaccumulation of Polygonum hydropiper responding to Mn.
结果表明:锰在水蓼叶片非活性代谢部分的积累是其解毒耐锰的主要机制之一;水蓼叶片中的锰大部分以水溶性有机盐或草酸锰的形态存在;在锰浓度处理为8000μmol/L时,叶绿素a含量显著降低,而在其它处理条件下,叶绿素a无明显变化;在锰处理≤5000μmol/L时水蓼叶片的细胞膜还没有受到明显伤害;水蓼叶片的可溶性蛋白含量随锰处理浓度不同而变化,说明植物在代谢和结构上发生了调整;随锰处理浓度的增加,水蓼叶片SOD和POD活性提高,保护酶活性的提高又可清除活性氧自由基,这是水蓼耐高锰和累积锰的一种生理响应机制。
