吸附法治理汞废气的机理研究

该文对载银活性炭吸附汞蒸气的机理进行了探讨 ,通过电子探针和扫描电镜对载银活性炭及被汞“饱和”的载银活性炭进行微观结构分析 ,结果显示 ,银在活性炭中主要分布于活性炭的凸面处 ,汞只在有银存在的地方出现 ,表明普通活性炭不具备吸附汞的能力 ,载银活性炭吸附汞属于以银为核心的多分子物理吸附 ,工业上的“饱和”载银活性炭仍具有一定的吸附汞蒸气的能力 ,为交替式吸附床的结构设计提供了技术依据 .     

Polarized Emission of Molecular Film With Lanthanide (Ⅲ) Complex

1 Results In the coordination system by using complexation with organic ligand, the ff emission of lanthanide(Ⅲ) (Ln(Ⅲ)) is induced the excitation energy transfer form the organic chromophore under the light-irradiation. However, there are not so much number of reports to discuss the energy relaxation mechanism in such complexes with Ln(Ⅲ). Recently, we succeeded firstly to estimate the rate constant of the energy transfer between the ligand and Ln(Ⅲ) in Pr(Ⅲ)-phenanthroline analogs[1]. Here, we will di...

PAN 活性炭纤维表面结构

通过元素分析(EA)、X射线衍射(XRD)、X光电子能谱(XPS)、差热分析(DTA)等方法，证明不同比表面积的聚丙烯腈(PAN)活性炭纤维(ACF)具有不同的表面微结构。结果表明，高比表面积的ACF、与低比表面积的ACF相比，类石墨微晶尺寸小，边缘活泼C原子数目多，本体C原子质量分数大，N、H、O等杂原子质量分数小，羧基、酰胺基团的数量少，醚基数量多。     

Modeling and Control of Active Suspensions for MDOF Vehicle

The conventional method for analyzing active suspension control for a vehicle is only to analyze a quarter or half car with a lower order degree-of-freedom (DOF) model, but such models do not actually model practical applications. Accurate models of a suspension control system require a multi-degree-of-freedom (MDOF) vehicle model with a detailed model of the controller. An MDOF model was developed including the influence of factors such as the engine, the seats, and the passengers to describe vehicle motion using a reduced order model of the controller designed by using the H∞ control method. The control system performance has been investigated by comparing the H∞controller with a linear quadratic (LQ) controller.
