氢化

As known as traditional viewpoint, microbe could produce hydrogen continuously only when microbic cell is fixed, so present tests of this process offen adopt this process fixed-cell technology of pure microbe and were in the scale of batch fermentation test. Now the larggest ability of bio-producing hydrogen was 20mLH〓/g biomass·h produced by Rhodospirillum rubrum and 1. 6mLH〓/g biomass·h produced by Clostridium butyricum .

专家组成功地模拟了罗家的&自燃&现象：含磷的矿物质在有细菌和具备还原性条件下分解成磷化氢气体，而磷化氢气体在一定潮湿的空气环境下自燃，继而引发空气中通过老鼠洞挥发出来的甲烷体燃烧。

Acetate groups charge ZnO nanocrystals negatively and passivate the surfaces,reducing the surface defects and visible emission centers. Resultantly, the increase of acetategroups lead to the quench of visible emission and improvement of photoluminescenceproperties. At appropriate concentrations, the hydroxide groups mainly passivate the surfaceand improve the photoluminescence properties.

研究发现，氢氧化锂/醋酸锌的比值对胶体氧化锌量子点的发光性质有重要影响；醋酸根基团通过使氧化锌粒子带负电荷并钝化其表面，使得氧化锌纳米点的表面缺陷和可见发射中心大大减少，因此醋酸根浓度的增大导致了可见发光的淬灭和发光性质的增强；氢氧根基团在中等浓度时主要起钝化氧化锌表面的作用，使产物的发光性质得到改善。

The conclusions are showed as followed:1. This paper demonstrated that microbe adapt better to the environment of system and have better fastness when the organic loading is variational as soon as the reaction is startuped naturally;2.
