Both desorption and grain size control REE in the surface sediments of the subaqueous Yangtze delta. 长江水下三角洲表层沉积的REE受到粒径和盐度的双重控制。
Shallow groundwater is controlled by physical chemistry action in aeration zone. Eluviation and desorption/ adsorption are major actions to control fluorine move. 该区浅层地下水主要受控于包气带的物理化学性质,淋溶、解吸/吸附作用是控制地下水中氟迁移的主要作用。
So study on the process to adsorption and desorption of oil contaminants in sands will provide gist for effective oil contamination remediation and control coast oil pollution. 深入研究石油污染物在沙质海滩中的吸附与释放过程,对于海滩石油污染的控制和原位修复具有重要的科学价值。
We found out that the main principle of humidity regulating materials is adsorption and desorption of H2O by the pores and channels in the material. In this paper, the humidity control ability of materials has been analyzed bu the theory of capillary effect and solid surface adsorption. 常用的调湿材料其湿度调节的原理主要是孔穴孔道的吸附和解析作用,本文通过毛细管效应原理和固体表面吸附性质对材料调湿能力进行了理论分析。
According to the problems existed in the electrolytic equipment of pressure desorption, the modification and adjustment in technology, automatic control and equipment are made repeatedly. 针对以往加压解吸电解设备存在的问题,在工艺、设备、自动控制等方面进行开发。
After heavy metal entering into the soil, the first and inevitable course is "adsorption and desorption", which is one of the most important physical and chemical courses to control heavy metal activity of soil. 重金属进入土壤后,首先和必然发生的过程是吸附和解吸,而吸附和解吸是控制土壤重金属活性的重要物理化学过程之一。
