In conclusion, the pregnant result of group C was better than group B, D, E.2. The positive substance of TNF-αin group B was significantly increased than group A in the hypothalamus nuclei, neurohypophsis, pars intermedia, ovary follicle, corpus luteum, however, the expression of TNF-αwas obviously decreased in adenohypophysis.

When aborted rats in group E were treated with the dose of 50 IU/g IFN-γ, expression of TNF-αin this group was compared with the other four groups, the results were as follows: Compared with group A, the nucleus pre-opticus medialis, nucleus pre-opticus mango celluaris, nucleus periventricularis hypothalami, nucleus ventromedialis hypothalami, nucleus dorsomedialis hypothalami, nucleus arcuatus hypothalami and pars intermedia had a highly expression of TNF-α, in the other nuclei of hypothalamus, neurohypophsis and adenohypophysis, the change was not significantly, the expression of TNF-αin follicle and corpus luteum were decreased distinctly, the variation in uterus was slight and no difference was exsited; Compared with group B, the expression of TNF-αin nucleus nucleus lateralis hypothalami, nucleus ventromedialis hypothalami, nucleus arcuatus hypothalami, adenohypophysis and uterus presented a remarkable enhancement, conversely, the TNF-αexpression in the nucleus pre-opticus medialis, nucleus pre-opticus suprachiasmaticus, nucleus supra-opticus, nucleus pre-opticus mango celluaris, nucleus periventricularis hypothalami, nucleus paraventricularis hypothalami, neurohypophsis, follicle and corpus luteum had been significantly decreased; Compared with group C, the nucleus pre-opticus medialis, nucleus ventromedialis hypothalami, nucleus dorsomedialis hypothalami, nucleus arcuatus hypothalami, adenohypophysis, pars intermedia and uterus had upregulated the expression of TNF-α, however, it was decreased in the nucleus periventricularis hypothalami and corpus luteum; When compared with group D, the expression of TNF-αin nucleus lateralis hypothalami, nucleus dorsomedialis hypothalami, nucleus ventromedialis hypothalami, pituitary, follicle and ovary stroma were obviously enhanced, while in the nucleus supra-opticus and nucleus arcuatus hypothalami, the situation was definitely opposite, in the other parts, the change was not significant.

The finding of the blue-shifted F-He-H... Y (Y=N〓, CO and He) systems, where the proton-donor was incapable of rehybridization, indicated that rehybridization is not a generally application driving force for the blue shift. There were other two novel blue-shifted systems discovered in this study. They were lithium bonding systems and dihydrogen bonding systems. On the basis of state-of-art NBO analyses and potential energy surface analysis, it was demonstrated that Pauli/nuclei repulsions cause the blue shift.

在对蓝移理论的研究中，本文发现了一类质子给予体不能进行重杂化的氢键蓝移体系，说明了&超共轭—重杂化&理论的不完善；而将Pauli／nuclei排斥理论应用到本文新发现的两类蓝移体系——锂键体系和双氢键体系，可以很好的解释它们的蓝移现象，从而更进一步的扩展了这一理论。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
