Vocal music stage performance is a complicated process combining both the functions of the human body and various psychological factors. This paper attempts to research the characteristic of imagery of the Chinese vocal music stage performance fromthe perspective of the Chinese traditional culture,deeply analyzing the function and influence of the characteristic of imagery upon the lyric of songs,body language of the performer and the inner feelings,facial expression and costume of the singer in order to improve the vocal music stage performance of the performer.

This paper presents the effects of chemical compositions of austempered ductile iron （ADI） on casting quality, heat treatment process parameters and mechanical properties of final products. Through experiment and production practice, the impacts of carbon equivalent on ADI and its mechanical properties have been studied. Proper content ranges for carbon and silicon have been obtained to avoid ADI casting shrinkage and graphite fioatation, as well as to achieve the optimal mechanical properties. According to the impact of silicon content on austenite phase transformation, the existing form of carbon in ADI has been analyzed, and also the formula and diagram showing the relationship between austenitizing temperature and carbon content in austenite have been deduced. The chemical composition range for high performance ADI and its control points have been recommended, to serve as a reference for production process.

Six topoisomers consisting of diethoxy- carbonyl glycoluril have been successfully synthe- sized in one-pot by using a “figure-of-seven” building block through anti-connectivity and syn-connectivity reactions, respectively. The structures of all six topo- isomers were first determined by X-ray crystallogra- phy. The finding that (±) CT isomers are the dominant products under thermodynamic control can be ex- plained by the calculated relative energies of the six topoisomers. That the (±) CT isomers have the lowest energy is most likely due to the additional in- tramolecular electrostatic interactions between –NO2 and –OMe groups. The biological activities of the topoisomers were primitively investigated and the results of bioassay showed that the six topoisomers possessed obvious difference of herbicidal activity.
