In order to prove the reliability, test studies have been primarily carried out in the indoor soil bin. The data of the vehicle driving state parameters under the same or different terrain are analyzed. The process curves are compared by different control schemes. The theoretical model of the optimum driving state is reliable and fuzzy control scheme is feasible. The disturbances and unknown factors of control system are analyzed. Test results prove that the half-tracked air-cushion vehicle can drive steadily under control of the computer. At the same time the sensors used to measure soil mechanics characteristics on line need to be developed. And it is the important problem to be solved in the future study. The necessary regulation and correction are put up. So the studies in this paper provide some instruction for the further research work.
为了验证本文提出的最佳工作状态及最佳垫压理论,并分析控制系统的可靠性和稳定性,本文在半履带式气垫车的模型车上,在室内土槽中进行了初步的实车性能和理论验证试验,考察了在同种和不同土壤条件下气垫车的行驶状态参数的测量数据,比较了采用不同控制方法下的过程曲线,验证了最佳工作状态的理论模型和模糊控制系统方案的可行性与可靠性,从而保证了采用自整定模糊PID控制器能够使半履带式气垫车在稳定行驶最佳工作状态下;同时通过试验研究,分析了系统中各干扰与未知因素,对控制方案进行了相应的调整和修正,为今后进一步的研究工作提供了一定的指导。

What's more the relations between different asset are classified to three groups which are the fundamental-derivative relation、the cross sectional relation and the comprehensive relation, on basis of which the asset pricing anomalies are classified individually to different groups.(2)The price model of the capital asset is constructed trailing the path of the asset value's incrementing and transferring. And then a three–factor model is established which can be utilized by the empirical researches. Concretely, under the capital chain, we conclude the relation between the stocks and the corporate assets is a fundamental-derivative one and the research object is the capital asset under the capital chain.
具体而言,本文在资产链的角度下分析股票和公司资产之间的"基础—衍生"关系,明确了本文的研究对象为资产链下的资本资产;建立了公司资产的价值,将公司资产和其基础资产公司的财产联系了起来,构造了资产链上第一个节点——公司资产的价值;将公司资产和资本资产进行了关联,在考虑公司资产变为资本资产的流动性增值后,建立了资本资产的价格模型;在前文资本资产价格模型的基础上进行了收益分解,基于此引入了具有长中短不同决策周期的三类投资者,在存在无风险资产和不存在无风险资产两种情况下分别建立了可用于实证的三因素模型。

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。
