盟誓是春秋时期不同政治实体进行交往的重要手段。由于王权、神权逐步衰落,诸侯之间的争斗愈发激烈,弃盟、改盟现象亦随之频繁起来。弃盟、改盟破坏了夏、商、西周的盟誓制度,加速了春秋政治乱象的发展,并与礼制相互影响,在一定程度上... 盟誓是春秋时期不同政治实体进行交往的重要手段。由于王权、神权逐步衰落,诸侯之间的争斗愈发激烈,弃盟、改盟现象亦随之频繁起来。弃盟、改盟破坏了夏、商、西周的盟誓制度,加速了春秋政治乱象的发展,并与礼制相互影响,在一定程度上体现了春秋时期新旧礼制交织的时代特征。 展开更多

Producing of renewable energy--as well in world as in national context--was necessitated by the synergistic effect of the climate change and the long term, continuous price rise of the fossil energy carriers. Main reasons for the spread of renewable energy sources are to increase the security of the energy supply or in optimal case, to realize the total energy independence. Furthermore, numerous studies demonstrate that production and also utilization of biofuels--including the organic waste-based fuels--are environmentally sustainable and have positive impact for the security of energy supply. This paper deals with production of biogas (from agricultural organic wastes) for energy. The production of biogas and the other biofuels will help you find the balance in agriculture because they can be generated from biomass, agricultural wastes and non-food plant material. In addition to the objective of saving emissions, EU biofuels policy aims to ensure the necessary energy and to decrease unemployment. So this paper would like to contribute to the EU requirements through the research. The producing system can be expansible by utilization of other organic material, so it is supported the efficient operation. 展开更多
