The 4D Klein-Gordon, Dirac and Quantization Equations from 5D Null Paths

Results from 5D induced-matter and membrane theory with null paths are extended to show that a particle obeys the 4D Klein-Gordon equation but with a variable mass. The Dirac equation also follows, but raises concerns about 4D quantization in the two natural 5D gauges, and reopens the question of a Regge-like trajectory for the spin angular momenta and squared masses of gravitationally-dominated systems.     

治理理论视角下高等教育管理的社会参与

我国高等教育管理权曾一度为政府所控制，社会力量很少能够参与到高等教育管理中来。公共行政领域的治理理论，为社会参与高等教育管理提供了理论依据。实现高等教育管理的社会参与，不仅有待于社会力量的积极发展和完善，而且政府和高校也要主动吸收社会力量参与管理。

期权理论在高新企业价值评估中的应用

分析了高新技术企业特点，说明了传统的企业价值评估方法不能应用于对高新技术企业的评估。如果把高新技术企业投资看成是为了获得一个未来取得现金流的机会，高新技术企业具有期权性质，就可以用期权理论及Black-Scholes模型评估高新企业的价值。     

The mechanism of ethylene polymerization by nickel salicylaldiminato catalysts - Agostic interactions and their kinetic isotope effects

The ethylene polymerization reaction of a neutral nickel catalyst was studied by DFT calculations at the Becke3LYP/6-31G(d) level of theory. As in related cases a β-agostic bond stabilizes the nickel alkyl ground states. Transition states for the insertion of the olefin show a distinct α-agostic interaction, which has not been observed for late metal polymerization catalysts before. An ethylene-alkyl complex was identified as the resting state of the reaction. The overall barrier height of the reaction amounts to 17.54 kcal/mol, which slightly increases to 17.60 kcal/mol for the polymerization of deuterated ethylene. Therefore, a small positive kinetic isotope effect (k_H/k_D = 1.09) can be calculated, which is caused by the α-agostic interaction in the transition state. A comparison to other late metal based polymerization systems reveals that the ethylene coordination step of highly active catalysts is significantly lower in energy compared to catalysts which are only moderately active.     

Integral Kernel Operators on Fock Space – Generalizations and Applications to Quantum Dynamics

A general theory of operators on Boson Fock space is discussed in terms of the white noise distribution theory on Gaussian space (white noise calculus). An integral kernel operator is generalized from two aspects: (i) The use of an operator-valued distribution as an integral kernel leads us to the Fubini type theorem which allows an iterated integration in an integral kernel operator. As an application a white noise approach to quantum stochastic integrals is discussed and a quantum Hitsuda–Skorokhod integral is introduced. (ii) The use of pointwise derivatives of annihilation and creation operators assures the partial integration in an integral kernel operator. In particular, the particle flux density becomes a distribution with values in continuous operators on white noise functions and yields a representation of a Lie algebra of vector fields by means of such operators.     

超声波在还原染料染色中的应用研究

本文是继文献[1]、[2]之后,对超声波染色进行理论分析的实践证明之后,以还原染料上染纯棉织物的小试入手,讨论了超声波对还原染料染色的可能性。结果表明,采用超声波染色技术,不但可以提高染料的上染百分率,增加匀染、透染性,还可以实现织物的低温短时间染色,同时还可以采用较少的染料获得实验所要求的色泽深度。具有广阔的发展前景。     

混沌动力学和湍流的统计理论

湍流是一个非线性复杂大系统,精细地研究其奇异吸引子的几何结构和动力学行为是不可能和不必要的,必须进行统计研究。湍流具有结构这一发现并不否定统计研究的必要性和合理性。混沌动力学为在更高层次上发展湍流统计理论奠定了基础。
