Based on the magnetic-elasticity nonlinear kinetic equations, physical equations, electrical kinetic equations and the expression of Lorentz forces, the magnetic-elasticity kinetic buckling equation of a current-carrying plate applied mechanical load in a magnet field were derived. The equation was transformed into the standard Mathieu equation by using Galerkin method. Thus, the magnetic-elasticity kinetic problem was changed into a problem of solving the Mathieu equation.

The experiments for determining the reaction kinetics of Daqing atmospheric residue were performed in a continuous flow, expanded bed rector. Four-lumped reaction kinetic model was developed to account for various feed and product fractions of Daqing atmospheric residue (gases, gas oil, residue and coke). The amounts of olefins and alkyls in the gas products were further analyzed to determine reaction kinetics of gas product distributions. Hence, a combined five-lumped reaction kinetic model was obtained for catalytic pyrolysis of Daqing atmospheric residue. The kinetic constants both in four-lump model and five-lump model were evaluated. A simulator for catalytic pyrolysis process was developed by incorporating the five-lumped kinetic model into the hydrodynamic flow model.

In order to prove the importance of three-body interaction, accurate ArH〓 potential surface and accurate ArAr potential surface are added to construct a two-body potential surface. We found that this potential surface is corresponding with a deep potential well and a tight structure, which is far from the real structure of Ar〓H〓. Obviously, this two-body additive potential surface is not suit in this system.

On the basis of the kinetic equation of substrate reaction in the presence of urea or guanidine hydrochloride, all microscopic kinetic constants for the free enzyme and enzyme-substrate binary and ternary complexes have been determined. The results of the present studies indicate that:①In the presence of urea or guanidine hydrochloride, enzyme-substrate complexes lose their activity less rapidly than the free enzyme. Therefore, both substrates, NADPH and 7, 8-dihydrofolate, protect dihydrofolate reductase against inactivation.②The denaturation of dihydrofolate reductase by urea follows single-phase kinetics, and changes in enzyme activity and tertiary structure proceed simultaneously in the unfolding process, so it may be an"all or none"process.③The GdnHCl-induced unfolding of the dihydrofolate shows a biphasic transition, while the change in the enzyme activity is a single exponential process. The rate constant of inactivation is consistent with that of the fast conformational change. Therefore, the kinetic intermediate of protein unfolding should be a partially folded and inactive form.

我们根据在脲或盐酸胍存在下的底物反应动力学方程求得游离酶和酶底物二元、三元复合物的微观动力学常数，结果表明：①酶-底物二元、三元复合物的失活速度明显慢于游离酶，说明两个底物二氢叶酸和NADPH对酶的失活都具有一定程度的保护作用；②在脲作用下，酶的失活和构象变化均为单指数项过程，而且酶的活力丧失和三级结构变化是同时发生的，说明二氢叶酸还原酶的脲变性可能是一个"全或无"的两态过程；③在盐酸胍作用下，酶的构象变化为两相过程，而失活则是单指数项过程，酶分子构象变化的快相速度常数与失活速度常数基本一致，因此我们认为二氢叶酸还原酶的盐酸胍变性过程中存在一个没有活力、但仍具备一定空间结构的变性中间体。
