查询词典 adsorption

Under laboratory conditions, this paper studied the adsorption of different concentration 40, 400 and 4 000 μgL^(-1 polycyclic aromatic hydrocarbons including low molecular weight acenaphthylene, phenathrene and chrysene and high molecular weight benzo perylene in seawater by the leaf litters of Kandelia candel and Avicennia marina at different decomposition status.

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.
