Hydrotalcites belong to a family of anionic clays. Because of its special composition and structure, hydrotalcites are shown highly activity and selectivity in catalytic reaction, such as hydrogenization, polymerization, and condensation.

水滑石为一类阴离子型层状粘土，由于其组成和结构的特殊性，使其在催化加氢、聚合、缩合及醇类转化等有机反应中表现出高的催化活性和选择性，同时，它们还可以作为吸附剂、阻燃剂和热稳定剂等。

Although nitric oxide hyperproduction due to inducible NO synthase is observed in asthma and COPD, nitrotyrosine formation via the reaction between NO and O(2)- in addition to the myeloperoxidase-mediated pathway.

虽然哮喘和COPD患者均存在由诱导型一氧化氮合成酶催化的一氧化氮过度产生，但是，硝基酪氨酸主要通过除髓过氧化物酶介导途径之外的NO和超氧阴离子反应形成。

Owing to the action of space separation in inclusion compound and the solvationof water for isolating the charge in ion pair, the lifetime of C〓 anion radical inaqueous system was obviously longer than that in organic solvents.

对同种胶束，给体分子的取代烃链越长，意味着其疏水性增加，导致给体端N原子与C〓分子间距离缩短，从而降低了阴离子自由基的寿命。

In order to improve the solubility of the CNTs in solution without any structural damage, the surface-modified approach with noncovalent bond is considered. Anionic polyelectrolyte, poly(sodium 4-styrenesulfonate), used as modifier was applied to overcome the difficulty of CNT's dispersion into insoluble and infusible polymer matrix.

为了使奈米碳管在高分子基材中达到良好的分散性，又不会破坏其原始特性，本研究采用非共价键结表面改质的方式来进行奈米碳管之分散，研究中以阴离子型聚电解质，Poly(Sodium 4-Styrenesulfonate)，为奈米碳管分散剂。

The procedure employs the attachment of a small anion to neutral molecules, which renders them ionizable with ESI.

这种方法采用一个小的阴离子与中性分子形成复合物，可以有效提高中性分子的电喷雾离子化能力。

Adopt poaching and alcohol sinking to get coarse polysaccharide, then take MCP, MCP-1 and MCP-2 for studing in antioxidation activities. They have strong ability for scavenging free radical only in DPPH system and oxidation system of linolic acid induced by alkane radical, but negatively in hydroxyl system and in super-oxygen anions system. And MCP-2 is better than MCP-1, so we choose enzymolysis method to remove protein.

采用水煮醇沉工艺提取粗多糖，然后对MCP、MCP-1和MCP-2进行抗氧化活性试验，三者在DPPH体系和烷基自由基引发的亚油酸氧化体系中具有明显的清除自由基能力，在羟基自由基体系和超氧阴离子自由基体系中则呈现负清除能力，其中MCP-2要优于MCP-1，因此选用酶解法除蛋白。

CMTC crystal belongs to metallorganic complex compounds and growth units are in the form of complex anions. Therefore, there are probably some unsaturated electrovalent bonds on the growth face, which undergoes a "restruction" process by bond linkages until a stable state with least surface energy is reached.

2CMTC晶体是配合物型晶体，以配位阴离子基团形式向生长界面堆积生长，因此在界面上很可能会存在着一些不饱和的离子悬键，悬键之间可能相互连接进行&重构&以达到表面自由能最小的稳定状态。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
