The results show that a MgSnO3·H2O conversion film is formed by treatment in the stannate solution at 90℃, and the immersion test and potentiodynamic polarization show that the corrosion resistance of the AZ91D alloy is improved to some extent.

结果表明：锡酸盐转化处理后合金表面形成了以MgSnO3·H2O为主要成分的转化膜，可对合金起到一定的防护作用；转化膜由细小的球形颗粒密积而成，颗粒之间存在间隙，它可以为化学镀镍的前处理过程提供良好的吸附条件；转化膜上的化学镀镍层组织致密、无缺陷， MgSnO3·H2O转化膜在镀镍层与基体之间起到过渡作用，镀层的磷含量达到9%，与基体结合良好；在3.5% NaCl (pH=7)溶液中的动电位极化测试表明，镀镍以后的合金在阳极极化过程中发生了明显的钝化，耐腐蚀性能进一步提高，对基体起到了较好的防护作用。

Samples of the equilibrium solid phase in Rb_2SO_4-PEG4000-H_2O system at 25 ℃ analyzed by TGA showed that they consisted of anhydrous salt. Six zones were observed in the complete phase diagram. They are L, L+L, L+S, 2L+S and L+2S, respectively. The binodal curves were given using a four-parameter equation y = a + bx~(0.5)+cx+dx~2. The tie lines were correlated by the Othmer-Tobias and Bancroft equations.

同时我们用热重分析仪对Rb_2SO_4—PEG 4000—H_2O三元体系在25℃时的平衡固相进行分析，发现在实验研究的温度范围内，体系的平衡固相均为无水盐，且在体系的完整相图中，观察到六个相区，分别为L，L+L，L+S，2L+S和L+2S相区，即非饱和的单液相区，非饱和的双液相区，饱和的单液相区，饱和的双液相区和两种固相(Rb_2SO_4，PEG 4000)存在的饱和单液相区。

The trivalent chromium passivation film based on zincate plating obtained has compact structure with no obvious crack, and excellent anticorrosion performance. Different compositions are detected from the surface to inner film, the surface mainly contains Cr2O3-Cr3-ZnO compound, the inner (1030 nm to surface) composes of Cr2O3-ZnO-Zn.The forming process of passivation film possibly consists of four steps which are zinc dissolution, basic area appearance, gelatiniform film forming and converting to passivation film.

结果表明：锌酸盐镀锌层的三价铬钝化膜表面结构致密、无明显裂纹，具有较好的耐腐蚀性能；这种钝化膜表层与里层的组成不同，表层的组成为Cr2O3-Cr3-ZnO共混物；里层(离表层10~30 nm处)的主要组成为Cr2O3-ZnO-Zn共混物；钝化膜的成膜过程可能包括镀锌层的溶解、碱性薄层的形成、胶状膜的形成和胶状膜转化成钝化膜4个步骤。

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。
