CoAPO-5 molecular sieve was hydrothermally synthesized using pseudo-boebmite, phosphoric acid (85%), tetrahydrate cobaltous acetate as raw material and N, N-diehtyl-ethanolamine as tern- plating agent.

以拟薄水铝石、质量分数85%的正磷酸、四水合醋酸钻为原料，N， N-二乙基乙醇胺为模板剂，水热法合成了CoAPO-5分子筛。

E., monodentate,bidentate and complicated multidentate chain-structured or web-structured CIPs.

利用曲线拟合技术对其光谱的ν1-SO峰进行分峰，获得了不同湿度下ZnSO4微液滴中各组分的量化信息：高湿度时，液滴中主要包含自由的水合SO；随着湿度降低，自由SO逐渐向单齿、双齿接触离子对转化，并在湿度为66%和34%时分别达到其最大值；继续降低湿度，复杂的链状或网状接触离子对逐渐成为液滴中的主要成分。

Both niobic acid and niobium oxide can be used as either catalyst,promoter or support in the heterogeneous catalytic reactions,such as selective oxidation,hydration,hydrolysis,alkylation,dehydrogenation and hydrogenation,because of their acidic and redox properties.

作为一种新型的催化材料，铌酸-氧化铌由于其独特的酸性和氧化还原性正受到越来越多人的关注。它可以作为催化剂的活性组分、助剂或载体使用，在烃类转化、选择性氧化、水解、水合、缩合、加氢脱氢等若干酸碱和氧化还原反应中得到广泛的应用。

These products include sodium percarbonate, percarbamide, 4Na 2SO 4·2H 2O 2·NaCl adduct, tertiary amine oxides, hydrazine hydrate, dihydroxy benzene, quaternary ammonium salt hydrogen peroxide and methylethyl ketone oxime.

Hydration and hydrolysis processes restrained each other. Hydration made hydrolysis products except Zn(OH2 difficult to hydrolyze further, while hydrolysis process cumbered hydration reaction.

水合作用和水解作用互相抑制，水合作用阻碍了水解产物进一步水解（Zn2除外），水解作用使得水合变得困难。

Crystal structures of bar-headed goose aquomet hemoglobin and greylag goose oxy Hb were determined and compared, which confirms the previous postulation that α119 mutation leads to the higher oxygen affinity of bar-headed goose Hb, but indicates that β125 mutation might also make part contribution.

通过对斑头雁水合高铁血红蛋白和灰雁氧合血红蛋白的晶体结构研究，证实了前人关于α119突变导致斑头雁血红蛋白的氧亲和性提高的假说，同时推测β125突变可能也有部分贡献。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
