With this so-called consumer responsibility method, the emissions embodied in imported electricity are calculated with source-specific emission factors. Using the new method,we estimate CO2 emissions in 2005 and 2010. Compared with those derived from the producer responsibility method,the power exporters' emissions decreased sharply. The emissions from the power sector in Inner Mongolia, the largest power exporter of China, decreased by 109 Mt in 2010. The value is equivalent to those from Shaanxi's power production and Canada's power and heat production. In contrast, the importers' emissions increased substantially. The emissions from the power sector in Hebei, the largest power importer of China, increased by 74 Mt. Emissions of Beijing, increased by 60 Mt(320%), in 2010. Thus, we suggest that the Chinese government should take the emissions, as calculated from the consumption perspective, into account when formulating and assessing local CO2 emission reduction targets.展开更多

The study contextualizes the research within the regional landscape and establishes a theoretical framework through a focused literature review. Key findings highlight the intersection of entrepreneurial activities and innovation dynamics, emphasizing the region’s unique contributions to the broader field. Discussions on discrepancies and unexplored territories within the articles offer insights into limitations and research gaps. The manuscript concludes by identifying future research avenues, providing a roadmap for ongoing inquiry into the entrepreneurial and innovative dimensions of the Central Region’s industrial sector. This synthesis underscores the importance of cultivating an entrepreneurial mindset and collaborative innovation strategies for sustainable industrial development in the region.展开更多

文摘用扇形探测技术代替了常规的测量方法以提高矿井瞬变电磁法超前探测资料的解释精度.在数据采集过程中,调整巷道迎头左侧拐角处天线的法线方向与左侧巷道壁的夹角,以60°,45°和30°的夹角进行探测,在迎头断面处布置2-3个测点,调整巷道迎头右侧拐角处天线的法线方向与右侧巷道壁以30°,45°和60°的夹角进行探测.通过调整天线的法线与巷道底板的夹角,探测巷道顶板、顺层和巷道底板方向上介质的电性变化情况.研究结果表明：在超前探测中使用扇形探测技术可提高巷道超前探测资料的解释精度,能更准确的反映出异常体的空间特征.在实际应用中探测成果图上钻孔中心点位置与实际揭露钻孔中心点位置误差不到2 m.
