我国低碳航运产业价值链的结构乘数效应     

甘爱平  詹凌晨  真虹  张婕姝 《上海海事大学学报》2016,37(3):47-51

针对航运低碳投资支出巨大的问题，运用结构性乘数，对我国用于低碳航运产业价值链中的支出产生的乘数效应进行研究.由两部门计算的简单投资乘数为1.547 7，由四部门计算的投资乘数均值为1.293 1.从长期看，乘数效应反映出航运低碳产业的投资收益大于投资支出，对航运业低碳减排具有现实和经济意义.  相似文献   

Reducing students’ carbon footprints using personal carbon footprint management system based on environmental behavioural theory and persuasive technology     

Shyh-ming Lin 《Environmental Education Research》2016,22(5):658-682

This study applied environmental behavioural theories to develop a personal carbon footprint management system and used persuasive technology to implement it. The system serves as an educational system to improve the determinants of students’ low-carbon behaviours, to promote low-carbon concepts and to facilitate their carbon management. To assess the validity of the system, high school students were chosen to participate in an experiment, the results of which reveal (1) the system has significant and positive short-term and relatively long-term effects on the reduction of their self-reported carbon footprint, (2) the system significantly improves their carbon footprint awareness and perceived behavioural control (PBC), and it also promotes behavioural subjective norms, (3) reduction of their self-reported carbon footprint is significantly correlated to PBC, carbon footprint awareness and attitude and (4) PBC is the most critical determinant of carbon reduction. Suggestions are accordingly made.  相似文献   

5-溴水杨醛甘氨酸修饰碳糊电极测定微量Cu2+的研究     

匡云飞  邹建陵  李薇  杨颖群 《衡阳师范学院学报》2006,27(6):44-46

在pH=9.0 H3BO3-Na2B4O7缓冲体系中,以5-溴水杨醛甘氨酸修饰碳糊电极为工作电极,Cu2 于 120mV(vs.SCE)处产生一灵敏的吸附波,其二阶导数峰电流与Cu2 浓度在4.0×10-9~8.0×10-7mol.dm-3范围内呈良好的线性关系,相关系数为0.9964,检出限为6.0×10-10mol.dm-3(3倍信噪比)。应用该法测定发样中Cu2 的含量,结果令人满意。  相似文献

Phase Transformations of Graphite and Carbon Black by Laser with Low Power Density     

孙景翟琪  雷贻文杨星 杜希文 《天津大学学报(英文版)》2007,13(5):318-321

The structure phase transformations of graphite and carbon black induced by pulsed laser were studied in this paper.Under irradiation with laser beam of 1.06 μm wavelength and power density of 106 W·cm-2,both graphite structure and carbon black structure were changed obviously.The results of Raman analyses and Transmission Electron Microscopy(TEM)observations show that graphite transforms into nanodiamond about 5 nm and carbon black is graphitized.It is demonstrated that graphite is the intermediate phase in the transformation from carbon black to diamond,and graphite is easier to transform into diamond by laser irradiation than carbon black.  相似文献
