About how the literary genre of ci-poetry came into being,there were two major viewpoints described as "natural evolvement of style" and "gradual change of temperament".

Application of Topological Index in Inorganic Hydrides ——study on the progressive changes of physicochemical properties of S block Hydride;

A gradation rule of the UV photo electron spectroscopy of non-conjugated sys-tems has been first proposed here ,its formula is as following:and this rule was verified by using the UV photo electron spectroscopy data of non-comjugatedsvstems.

A gradation rule of UV photo electron spectroscopy of the organic homologs has been first proposed here, its formula as following:The gradation rule was vermed by using UV photo electron spectroscopy ofconjugated systems.

On the basis of an analysis of the rules for sound variations and the functions of contexts as well as the cognitive nature of sound perception in English news broadcasting,this paper seeks to pursue the key to improving speech recognition in news understanding.

The results show that the additive property P of alkanes could be described as follows: P=aND1+bND2+cND3+d by study on the additive property of alkanes and their homologous regularity using topological index ND, where a, b, .
