论我国公民对政府监督机制的优化

公民对政府的监督是行政监督体系的重要组成部分，它主要包括公民决定政府领导人的去留，举报、检举政府违法行为和进行集体利益表达三种形式。然而，我国目前这三种形式还存在不少问题。扩大和保障公民的民主权利，健全公民的信访举报制度，完善公民的集体利益表达机制，是优化我国公民对政府监督的主要制度措施。

从认知角度看英汉"爱情"隐喻的异同

隐喻是人类认知的工具,它深深根植于人类的语言、思维和文化中。爱情,这种人类共同的情感,具有异常丰富的内涵,常常借助隐喻才得以表达。由于历史文化环境等的差异,中英中关于爱情的隐喻也大相径庭。本文通过分析大量中英文有关爱情的隐喻,从认知语言学的角度探讨爱情隐喻的异同。     

计算机帧时间对半实物仿真的影响

半实物仿真试验中,要求计算机帧时间与计算积分步长相一致,但在实际试验中不容易精确地做到。本文分析了这种不一致给半实物仿真试验带来的影响,给出了解决的办法,文章中还给出了一实例来说明。     

Field formation around negatively biased solar arrays in the LEO-plasma

Heavy emission caused by impacting plasma ions results in a fast discharging effect of the initially large surface potentials on the dielectric solar cells. This eventually counteracts the energization process of the plasma ions to the cover glasses and leaves no significant electric fields. Thus, with an existing thermal plasma, electrons are again able to reach dielectric surfaces. Strong localized electric fields of the order of several 10 kV/cm form near the interconnector-cover glass interface.     

EUV emission from normal galaxies

Using data from the Wide Field Camera EUV all-sky survey, we have established upper limits to the EUV flux from a sample of 30 bright, nearby, non-active spiral galaxies. These galaxies were chosen to be those most likely to be detected in the EUV on the basis of (i) low interstellar absorption within our own galaxy, (ii) brightness in other wavebands, (iii) high star formation activity, and (iv) proximity. The derived EUV upper limits are restrictive, and establish for the first time that the EUV flux escaping from galaxies does not constitute a major component of their bolometric luminosity, and in particular that it cannot be the sink for the energy injected into the interstellar medium by supernova explosions, as had been suggested following the failure to detect this power in the X-ray band.
