Theenvironmental risk of leachate from landfill with different operation modes depend ontheir accumulation amount rather than their sudden concentrations and fraction.(7)The high SRB metabolism activity and the accumulation of metabolitewere the main reasons of in-situ precipitation phenomenon of Cu~(2+) and Zn~(2+) inlandfill refuse in bioreactor landfill. Heavy metals in bioreactor landfill havemechanism of in-situ immobilization controlling by SRB metabolism. Thepredominant SRB in landfill refuse belongs to Desulfovibrio vulgaris sp.

The formation of six-horn star-like nickel diselenide was controlled by the oriented attachment mechanism and secondary crystallizing process: i.e., primary building particles oriented attaching along six {100} faces, the formed mesocrystals secondarily crystallizing and finally resulting in six-horn nanostars.

其形成过程主要受定向连接和二次结晶生长机理控制：即二硒化镍的初级结构单元沿其六个{100}面定向连接生长，所得介晶中间产物经过二次结晶过程最终形成六角纳米星形貌。

To investigate the expression, location and function, long distance PCR was used to expand the targets containing open reading frame. The expressive vectors of prokaryotic and eukaryotic cells were constructed after product purification and connecting with vectors. The prokayotic vectors were induced to express the protein by IPTG and the protein was seen by denaturalization PAG electrophoresis and dyeing. The eukayotic expressive vectors were transfected into culture cells and the protein was found in the nulceolus under the observation of the confocal microscope. The transfected cells were chosen by the geneticin (G418). The cell cyele was examined by flow cytometer and the cell numbers were reduced obviously in the stage of G〓-G〓 and G〓-M, but increased distinguishably in the S stage.

As for Leucaena leucocephala seedlings, MDA is not the main product of lipid peroxidation and Tephrosia candida seedlings do not only rely on SOD and POD action to reduce active oxygen content. Through comprehensive analysis on water holding capacity of leaf, cytomembrane permeability, MDA content and SOD, POD activity, Dodonaea viscosa seedlings show the highest drought resistance, then Leucaena leucocephala, Tephrosia candida the last.

干旱胁迫对银合欢膜系统损伤生成的主要降解产物不是MDA；山毛豆清除活性氧毒害作用主要不是通过SOD和POD的作用；通过叶片相对保水力测定及膜透性、MDA相对含量、酶活性变化情况的分析，3个树种中坡柳耐旱性最强，其次为银合欢，山毛豆居后。
