作者 赵茜 石泓 赵冬梅 《商业经济》 2011年第5期12-14,共3页
近些年来,黑龙江省财政对于农业发展的支持规模不断扩大,支持力度不断增强,保证了全省农业的稳定发展。当前,因农业正处于由传统农业向现代农业的过渡时期,不仅需要财政对农业给予大力支持,更需要优化农业资金投入结构,以提高财政投入效... 近些年来,黑龙江省财政对于农业发展的支持规模不断扩大,支持力度不断增强,保证了全省农业的稳定发展。当前,因农业正处于由传统农业向现代农业的过渡时期,不仅需要财政对农业给予大力支持,更需要优化农业资金投入结构,以提高财政投入效率;更需要改善支农资金管理体制,以提高资金利用效率,从而加强现代农业发展速度。 展开更多

This paper describes a particular stack performance realized in a building (school) at real scale by computation of the wind induced ventilation and a comparison of the stack performance (airflow rate extracted and wind speed) respect to other systems (wind catcher, wind jetter and wind turbine) are also showed. The realization of the system, actually working, shows the synergy between a plant design and installation using traditional energy sources with innovative engineering techniques providing for the use of integrative energy. In this case, the wind action plays an important role for the conditioning of the school, integrating and giving a significant energetic contribution to the air cooling system. The school building (a nursery) has been built in Modena and is actually working. 展开更多
