查询词典 adsorption

One novel polysaccharide—bacterial celluloseproduced by Acetobacter xylium have many distinguishing features, such as high purity, high crystalline great strength , high hydrophilic and good adsorption capacity.

细菌纤维素是微生物发酵过程中分泌的胞外多糖，由于其结构规整，聚合度强，纯度极高，结晶度高等特点，使其具备了独特的性能如高的吸水持水性和高的吸附性能等日益受到人们的关注。

The demulsification mechanism of PAMAM belongs to displacing mechanism. Acylamino groups of PAMAM of integral having strong polarity can take place chemical adsorption with the materials of strong polarity in the exterior of oil drop and be participated in into the membrane, which will result in adsorbed crude surfactant and other active materials to be partially displaced and reduce the intensity of interfacial film between oil and water.

其机理是由于整代的PAMAM具有强极性的酰胺基团，能与油滴表面的强极性的物质发生化学吸咐作用，参与成膜，能把原来吸咐的天然活性剂分子和其它活性物质部分顶替，削弱油水界面膜强度。

Simultaneity, the adsorption energies of single Si adatom on the H-terminated Si (100) surfaces are specially mapped out in this paper, from which the favorite binding sites and possible diffusion pathways have been achieved. The variety of the diffusion anisotropy with the coverage transforming is obtained. The energy barriers of the adatom diffusion are found to be higher than that on the clean surface, because the H atoms saturate the dangling bonds of the surface Si atoms.

同时，本文研究了附加硅原子在理想H-terminated Si(100)表面的沉积扩散行为，计算得到了一系列沉积点和可能的扩散路径；讨论分析了扩散行为的各向异性以及氢覆盖率对各向异性影响的规律，并且发现附加硅原子在H-terminated Si(100)表面上的扩散势垒比在清洁Si(100)表面上的高，我们认为这主要是因为氢原子饱和了表面上硅原子的悬挂键，提高了扩散势垒。

Enhancement of the heat and mass transfer of adsorbent is very valuable to adsorption refrigeration.

提高吸附剂的导热传质性能对吸附制冷的研究具有较大的实用价值。

An adsorption chilling system with a new type of composite adsorbent was developed and its performance was tested in our study.

研制了一台采用新型复合吸附剂的吸附式冷冻机组，并对该机组进行了性能测试。

Adsorption performance of the adsorbent for bilirubin was improved with the elevation of temperature.

BIA对胆红素的吸附量随吸附温度升高而增加。

These results indicated that the prepared BSA immobilized adsorbent could be an alternative choice for specific adsorption of bilirubin.

上述结果表明所制备的BIA为以特异性吸附胆红素为目的的血液净化材料提供了新的选择。

Use filter to purify 2 kinds of functions with adsorption, can handle alumina and adsorptive fluoride.

采用过滤和吸附净化二种功能，可处理氧化铝和吸附氟化物。

The selective depressive mechanism of (NH4)2 SiF6 for aegirine in flotation was also primitively discussed by zeta potential tests, measuring adsorption amount of sodium oleate on the mineral surface, and analyzing infrared spectrum.

通过对矿物表面ζ电位与油酸钠吸附量的测定以及红外光谱分析，初步讨论了氟矽酸铵对霓石选择性抑制作用的机理。

It is the fluorosilicic ion that exsits in the slurry and plays an important role in flotation, fluorosilicic ion not only reacted with Fe〓 on the surface of aegirine to form ionic compound, but also formed stable Si-F bond in Si-O etching reaction. Only ionic compound was obtained when it was attached to hematite surface according to the theories of coordination chemistry, Compared with SiF〓, Fatty acid ion preferentially acts with Fe〓 on the minerals surface, therefore, SiF〓 Can't obstruct the adsorption of collector on the surface of hematite completly, but can reduce the flotation recovery of aegirine selectively.

运用FTIR、XPS等测试方法仔细研究了氟硅酸盐抑制剂对含铁硅酸盐钠辉石的选择性抑制作用机理，氟硅酸盐在弱酸性条件下对赤铁矿浮选的抑制作用很微弱，而对含铁硅酸盐钠辉石强烈抑制，从而扩大了两者之间的浮选差异；SiF〓是矿浆中起抑制作用的主要成分，SiF〓不仅与钠辉石表面的Fe〓形成离子型配合物，而且还与Si-O键形成稳定的Si-F共价键，而与赤铁矿表面只能形成离子型配合物，根据晶体配位场理论，与SiF〓相比较羧酸根离子将优先与矿物表面Fe〓发生配位作用，因此SiF〓的存在并不能完全阻碍捕收剂在赤铁矿表面的吸附作用，却能够选择性地抑制钠辉石的上浮。
