本论文在结合电镜和荧光分析定位以及稀土离子对Ca〓信使系统组分的影响基础上，对Eu〓影响植物生长发育过程中的相关生理调节机制进行了解释。

In the current study, anoxic dechlorinations of p, p'-DDT,γ-HCH, HCB in the Liao River sediment were studied under the following conditions: without any additional short chain carbon substrates or vitamin B〓; with the addition of short chain carbon sources (including sodium lactate, sodium propionate or sodium acetate); with the addition of vitamin B〓; with the addition of both short chain carbon substrates and vitamin B〓, with the addition of sodium dodecyl sulfate , a kind of surfactant; the coexistence of the three chlorinated compounds.

氯代有机物一般都是典型的持久性环境污染物，其中部分氯代有机物还是环境激素类物质，例如，滴滴涕、林丹和六氯苯等，这些氯代有机物在环境中的迁移转化一直是国际环境化学领域的热点、重点课题。氯代有机物进入环境水体后，成为沉积物吸附态有机污染物的重要成分，天然水沉积物经常处于缺氧状态。因此，研究氯代有机物在天然水体沉积物中的缺氧脱氯行为是非常必要的。

In the current study, anoxic dechlorinations of p, p'-DDT,γ-HCH, HCB in the Liao River sediment were studied under the following conditions: without any additional short chain carbon substrates or vitamin B〓; with the addition of short chain carbon sources (including sodium lactate, sodium propionate or sodium acetate); with the addition of vitamin B〓; with the addition of both short chain carbon substrates and vitamin B〓, with the addition of sodium dodecyl sulfate , a kind of surfactant; the coexistence of the three chlorinated compounds.
