研究结果表明，漓江为雨源性河流，降雨时空分配极不均匀，70%的降雨量集中在漓江上游区域，全年62.7%降雨量和降雨时间集中在四个月内(即4～7月)，最大的日降雨量可达415.8mm；降雨量最小的月份出现在12月至翌年1月，仅100～110mm，占全年降雨量的6%左右，由此直接影响流域河川径流季节性的变化，造成洪水期和枯水期现象，周期性水量的变化是不为人们意志改变的一种自然规律。

By using electroporation transfects,the TGF〓expression vector were introduced into HL-60 cells.Thecells were allowed to grow for 1 day before beingsubjected to selection for the ability to grow in mediumcontaining 600ug/ml geneticin.Stable cell clones resistantto G418 sulfate were obtained after 2-3 WK growth withdrug-containing medium.Southern blot hybridization wascarried out.RNA slot have higher expression of TGF〓mRNA in HL-60 transfected.All results followed suggestedthat TGF〓 have suppressed the maliganant phenotype of HL-60 cells.

The last section of chapter 3 discusses the local sensitivityof the Bayes VaR when the contaminated probability ε close to zero. Consider adifferent contaminated class 〓,where Q consists ofsuch functions q that π can be regulized to be a proper probability distribution.

当〓是由定义在参数空间上的所有概率分布组成的分布类时，在没有观测数据和存在观测数据两种情况下，我们分别得到了基准先验分布〓下BayesVaR在ε污染类上对应概率水平的变化范围，该范围越小，表示基准先验分布下BayesVaR的稳健性越好，该范围越大意味着稳健性越差。

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。
