酶促反应过程中Brigg─Haldane稳态假说的适用性

本文利用非平衡态动力学方法探讨了Ｂｒｉｇｇ—Ｈａｌｄａｎｅ稳态假说对酶促反应的适用性．结果表明，在反应过程中间并不存在着一个时间区域使稳态条件成立，并采用分支理论得到了反应运力学方程的近似解。     

无有机溶剂、无相转移催化剂条件下稀H2O2氧化环己醇为环己酮

以钨酸钠与含氮和/或氧双齿有机配体原位（in situ）形成的络合物作为催化剂，在无卤素、无有机溶剂、无相转移催化剂条件下，实现了30％过氧化氢催化氧化环己醇为环己酮的反应。考察了13种不同的配体对环己醇氧化反应的催化作用，其中邻菲咯啉、草酸为配体时环己酮收率最好，分别达96％和95％以上。水杨酸，8-羟基喹啉和3，5-二溴水杨酸为配体时，也有很好的催化效果，环己酮收率超过90％，选用廉价的草酸为配体，对反应条件的优化研究表明，氧化反应的最佳条件为环己醇：W:草酸：30％H2O2的摩尔比为100：2：2：120，反应温度85-90℃，反应时间12h,环己酮收率95.19％。     

Studies of Several Systems with Air Electrode Electro-Synthesizing H2O2 on the Spot for Degrading Aniline in Aqueous

A gas diffusion electrode (air electrode) with a high current efficiency of electro-synthesizing H2O2 using O2 in air was prepared. The several systems with air electrode as cathode of electro-synthesizing H2O2 on the reaction spot for degrading aniline in aqueous--electro-Fenton system, photo-excitation electro-H2O2 system and photo-electro-Fenton system, were developed. The rates of decomposition of H2O2 and mineralization of aniline were experimentally measured respectively under different conditions, and the results indicated there has an excellent parallel relation between decomposition rate of H2O2 and mineralization rate of aniline. Especially, photo-electro-Fenton system, where H2O2 is decomposed the fastest, is the best system of oxidizing and degrading organic toxicants. Compared photo-electro-Fenton system with photo-Fenton system, important role is revealed in the interface of air electrode. In this paper, the mineralization mechanism of aniline in the photo-electro-Fenton system was also discussed.

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.
