For thin polycrystalline films, especially those with columnar structure, once the diameter of grains on the film surface is larger than the film thickness, the total area of above and under basal planes (film-substrate interface) will be larger than that of side plane. And if the film precipitates on the substrate with thermal expansion coefficient different from that of the film, great thermal stress will be introduced during annealing.

SOD activity was at peak in 5 mg/L Zn treatmenat, indicating greater ability to eliminate ROS caused by excessive Zn. Zn contents in roots and thalluses of duckweed in vivo increased significantly with increase of Zn concentration in solution at 0-5 mg/L Zn. When Zn concentration was higher than 5 mg/L, Zn accumulation in duckweed was no more increased significantly. And, the plant was damaged by excessive Zn.
结果表明:在Zn浓度为5 mg/L时,浮萍生物量并没有受到明显的影响,表现出较强的抗性;SOD酶活性也最高,表明清除氧自由基的能力也较强;Zn的积累随处理浓度增加而增加,在5 mg/L Zn处理时,也基本达到饱和,超过该浓度,吸收量则无明显的变化,同时浮萍也明显受到伤害。

The results show that the degradation effectiveness of PVA was optimum when potassium ferrate and sodium hypochlorite were jointly used as the oxidative agent. The removal rate of PVA and COD was more than 98% and 40% under the conditions that the concentration of PVA was 3.0 g/L and the pH value was 7.2, the dosage of potassium ferrate and sodium hypo chlorite were 0.32 g/L and 3.92 g/L, and the reaction time was 50 min. In the process of united oxidative degradation, the chain of PVA was cut off and many low molecular weight compounds were formed. The main degradation products were carboxyl compounds.

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。
