| 1 | Degree of coupling and coordination of eco-economic system and the influencing factors: a case study in Yanchi County, Ningxia Hui Autonomous Region, China显示文摘Based on the statistical data, we analyzed and evaluated the degree of coupling and coordination of the eco-economic system in Yanchi County for the period spanning from 1983 to 2014. The eco-economic system can be divided into socioeconomic and ecological sub-systems and their relationship can reveal the interaction state between the two sub-systems and help the local government to establish a coordinated development mode. An index system was constructed to assess the development of the two sub-systems before the evaluation of the degree of coupling and coordination. The principal component regression analysis was adopted to quantitatively assess the influences of natural, economic and social factors on the degree of coupling and coordination of the eco-economic system. Results showed that, from 1983 to 2014, the development trends of both sub-systems were increasing with the ecological sub-system having more fluctuations. The degree of coupling and coordination of the eco-economic system in the study area increased gradually from 1983 to 2014, but experienced five different development stages from the verge of disorder to favorable coordination. The development of the local social and economic conditions was the most important factor influencing the degree of coupling and coordination. The second most important factor was the financial support from the local government. In addition, the environment protection policies also played undeniable roles. Due to the diversity of the influence factors, the government should take comprehensive measures to promote the sustainable development of the eco-economic system. | LU Huiling ZHOU Lihua CHEN Yong AN Yiwei HOU Caixia | 2017 | Journal of Arid Land2017，9，3： | 12 |

| 14 | Structural Characterization of Petroleum Molecules by CID FT-ICR MS with Narrow Isolation Window显示文摘High resolution tandem mass spectrometry has been applied to obtain the structure information of petroleum samples. Here, we report a method for structural characterization of crude oil molecules by the collision-induced dissociation(CID) technology coupled with the high-field Fourier transform ion cyclotron resonance mass spectrometry(FT-ICR MS). The ion isolation window was narrowed down to 1 Da to distinguish the complex homologues contained in petroleum. Aromatic model compounds and crude oil samples were measured by CID FT-ICR MS at different collision energy levels. The fragmentation of model compounds with alkyl side-chains was found to be related to the size of the aromatic rings. The fragmentation of model compounds with archipelago structures depended on the length of the bridge alkylene chain. The prevalent reaction pathway of model compounds with naphthenic rings was mainly determined by the position of naphthenic rings in the molecules. On the basis of the fragmentation pathways, the structure differences of two crude oils were recognized as different content of naphthenic rings by CID technology with 1 Da isolation window. The NMR analysis was also applied to confirm the CID results. This study exhibits the great potential of CID FT-ICR MS with narrow isolation window in the structural characterization of crude oil molecules. | Liu Ling Zhang Yiwei Zhang Zhihua Hou Huandi Zhang Qundan Tian Songbai Wang Wei | 2018 | China Petroleum Processing & Petrochemical Technology2018，20，3： | 1 |
