利用贸易额的绝对值和指数实证分析了长江经济带与“一带一路”沿线国家的贸易地区结构. 结果表明: 长江经济带与“一带一路”沿线国家的贸易过于集中, 且进出口贸易的整体地区结构和主要10个国家的内部地区结构均有所优化, 但不甚明显, 其中出口的整体地区结构更为分散, 进口的内部地区结构更为均匀. 最后基于分析结果, 为促进长江经济带与“一带一路”沿线国家贸易地区结构合理化发展提出了建议. 相似文献

Reversible Conformational Changes of PsbO Protein Detected by Terahertz Time-Domain Spectroscopy 下载免费PDF全文
We used a terahertz time-domain spectroscope (THz-TDS) to detect the reversible conformational changes of PsbO protein induced by N-bromosuccinimide and Guanidine Hydrochloride. The veracity and sensitivity are confirmed by the fluorescence emission spectra. The results demonstrate that THz-TDS has both advantages and disadvantages in monitoring the denaturation process of proteins, which is important in applying THz-TDS technique to studying biomolecules. 相似文献
