Chapter three is the degradation of Abamectin in soils. The results show:(1) The decomposition of Abamectin is fastest in Aquic Cambosols while slowest in Udic Cambosols in five kinds of different soils.(2) Organic matter content in soil is the most important factor which influences the degradation half-life of Abamectin in soil, and their relative coefficient arrives at 0.9323, but pH value, total nitrogen, CEC and field maximum moisture capacity correlate little.(3) Soil organic matter, soil temperature and pesticide concentration can obviously affect Abamectin degradation in soil, in addition, the degradation half-life of Abamectin in sterilized soil is far more than that in non-sterilized soil, which maybe contributes to microorganism in soil. Chapter four is the microbial degradation of Abamectin.

第三章研究了阿维菌素在土壤中的降解，结果表明：(1)五种不同类型土壤中，阿维菌素在潮湿雏形土中降解最快，而在湿润雏形土中降解最慢；(2)土壤有机质含量与阿维菌素半衰期相关性较强，相关系数为0.9323，而土壤酸碱度、总氮含量、阳离子交换量和田间最大持水量等因子与阿维菌素半衰期相关性较小，说明影响阿维菌素在土壤中降解的最主要因子为有机质含量；(3)土壤有机质、土壤温度和农药浓度等因素对阿维菌素在土壤中的降解有较大影响，此外灭菌条件下其降解半衰期远大于未灭菌时的半衰期，这表明阿维菌素在土壤中的降解可能和土壤微生物有关。

The results show that although both Ni substitution and Mg vacancies are effective in desorbing hydrogen at lower temperatures, the substitution of Ni at the Mg site is energetically more favorable than the formation of Mg vacancies. The Ni atoms of NiF2 can replace some Mg atoms of MgH2 systems, the reaction of NiF2+3MgH2=MgF2+Mg2NiH4 during mill process is accelerated, thus, MgH2 with the higher stability can be changed into Mg2NiH4. Because of a ternary hydride Mg2NiH4 with lower stability forming, the dehydrogenating properties on Ni doped MgH2 systems are improved.

结果表明：Ni替代Mg和创造Mg空位对MgH2体系解氢而言，均发挥有益作用，而形成Mg空位所需能量(6.51 eV)高于Ni替代Mg所需能量(2.12 eV)，表明低温下Ni替代Mg对MgH2体系解氢而言更有利，至此NiF2中的Ni替代MgH2中的Mg，有利于加速化学反应NiF2+3MgH2=MgF2+Mg2NiH4向右进行，使结构稳定的MgH2发生转变，生成结构不稳定的Mg2NiH4，这样体系解氢过程不是通过MgH2，而是转变为通过Mg2NiH4进行，因此，Ni掺杂提高了MgH2体系的解氢性能。
