A modified γ-Al〓O〓 was prepared by a special precipitation method with aluminum nitrate solution containing a certain amounts of orthosilicic acid and ammonia aqueous solution. Compared with commercial γ-Al〓O〓, the modified γ-Al〓O〓 was an effecient catalyst for dehydration of tetrahydrofurfuryl alcohol to dihydropyran. The results revealed that the strong acid sites on the surface of the catalyst may play a crucial role in this reaction.

并以硝酸铝和氨水为原料，用沉淀法制备出一种高比表面和拥有较多强酸中心的γ-Al〓O〓，它在四氢糠醇开环脱水制备二氢吡喃的反应中有优良的催化活性，通过比较此γ-Al〓O〓和普通商业γ-Al〓O〓的Py-TPD图，发现强酸中心在制备二氢吡喃的反应中可能具有关键的作用。

Suppressor is the key part for IC instrument, and developing a high performance suppressor for IC instrument is quite important to gradient ion chromatography, to analysis of some ions which have strong affinities with the functional groups located on the surface of the pellicular ion exchange column packing.

抑制柱是离子色谱仪的一个核心部件，研制具有较高抑制容量的抑制柱对于离子色谱法的梯度淋洗、对于在分离柱上保留时间长的离子分析具有重要的意义。

The antioxidative action may involve trapping the initiating radicals generated by AAPH in the bulk phase, inhibiting the propagating lipid peroxyl radicals on the surface of micelles and regeneratingα-tocopherol by reducing theα-tocopheroxyl radical.

在均相溶液中，这些化合物单独使用时都是很好的抗氧化剂，但是只有杨梅树素产生了抑制期，其他化合物均降低了引发速率。

Because the tungsten from the phosphotungstic acid could pull out and deposit on the surface of catalyst, and the electronegativity of Mo-O is smaller than that of W-O.

最后，根据杂多酸的结构和相应的物理化学性质，对杂多酸与铂基催化电极电催化氧化甲醇的机理进行了初步探讨。

In addition, the recombination for large numbers of charge carriers would occur in the volume or on the surface of TiO_2. Therefore, the extension of the photoactive wavelength region of TiO_2 into the visible region and improvement of quantum efficiency are desirable for popularizing more TiO_2 photocatalyst, especially under solar light for industrial areas or poor interior lighting illumination in living spaces.

但纳米TiO_2具有较宽的禁带宽度，只能吸收太阳光中5%左右的紫外线，而太阳光中近45%的可见光在处理污染物中却得不到有效利用，因此太阳能的利用率较低，这就限制了其实际使用范围；另外，TiO_2半导体载流子的复合率较高，因此量子效率较低。
