查询词典 kinetic molecular theory

The kinetic behaviors of ethylene homo- olymerization and ethylene / l-hexene co-polymerization , catalyzed by the metallocene catalyst PS-DVB-MC in an 0.5 L stainless steel reactor , were studied. The effects of polymerization conditions on ethylene polymerization , such as concentration of catalyst , temperature of polymerization , pressure of ethylene , molar ratio of AI / Z r , etc ., were also investigated . Some leading results were as follows : the activity of the catalyst PS–DVB- MC for ethylene homo-polymerization was high ( 1.053 x 107 gPE / mol Zr·h ), but the molar ratio of AI / Zr was low ( 350:1 ); the catalytic ability for ethyleneα-olefin ( such as l hexene etc .) co-olymerization was great , and the corresponding activity come up to a maximum of 1.753 x 107 gPE / mol Zr·h while concenlration of l-hexene was 0.080 mol / L ; the molecular weight of polyethylene was about 180,000 , meanwhile the molecular weight distribution was narrow ( 2.19 ); the bulk density of polyethylene and ethylene / l-hexene co -polymer were 0.25 and 0.34 respectively .

Based on the molecular topological theory, a modified group dyeing indexL is introduced. It is used in the study of refractive index of the ketones and ethers. Relationship between the refractive index and molecular structure of 57 ketones and ethers is studied by using quantitative structure-property relationship technique. The reasonable molecular modeling equations are obtained by multiple regression for the prediction of the refractive index of ketones and ethers.

He integrated the ideological essence of Confucianism, Buddhism and Taoism, and used the " Natural kindniss " to express the Innateknowledge ontology, which composed his ontology theory ; He took this "Natural kindniss" as the basic of his theory, to pursue the Humanity realm which claim "One Unity of All Things" and the Easefulness realm which claim "free and easy", he thought both the two realms have the same mean, and finally proposed the theory of realm. On the Effort theoretically, Luo Jinxi emphasized "all lays down and breaks the unreal ontology theory", to fit the Natural kindniss in the just moment .He fused the Effort and the Ontology , which made the two together. As to the theory of "Awakening Oneself by discreet on One"s Own","The investigation of things" and "Filial piety and fraternalduty, Luo Jinxi also put forward an especial theory which made his thought into a perfect system and reached an extensive and proficient realm.

他融合儒释道的思想精华，用"赤子之心"来表述良知本体，构成其思想的本体论学说；并以此赤子良知为理论基点，追求"万物一体"之仁的境界与"生意活泼，了无滞碍"的洒脱之乐的境界，认为仁之境即是乐之境，乐之境即是仁之境，最终提出追求仁乐合一境界的境界论思想；在工夫理论上，罗近溪强调"放下一切、打破光景"，顺适赤子良知之当下状态，将工夫融释在良知本体中，即工夫即本体，即本体即工夫，表现出一种无工夫之工夫论；在关于慎独、格物、孝悌慈等论题上，近溪也提出了极具理论特色的观点，使其思想形成了一卓然圆熟的体系，达到了一"博通圆融"的境地。

This theory emerged from those philosophical and logical inquires Russell made in his early stage, when Russell use logical analysis to solve the semantics problem his meaning theory suffered. The foundation of the theory of descriptions is a theory of meaning, as this thesis presents, and its central notion includes two syntax rules. Based on the first order predicates calculus, this theory seems successfully solve some notable semantics problems and then assures Russell's denotation theory.

By applying game theory and contraction mapping theorem, a sufficient condition for the existence and uniqueness of Nash equilibrium in a multi-person non-cooperative game is proposed. Another implication in the sense of game theory is presented for the stability condition of supply-demand equilibrium in traditional economic theory. It can demonstrate the stability condition for supply-demand equilibrium in economic theory. So the stable supply-demand equilibrium of cobweb model in economics is in fact equivalent to the Nash equilibrium in game theory. That is a brand-new explanation for the conclusion in traditional economic theory.
