水资源在支撑江苏省高质量发展中发挥着重要作用,认识其用水结构及驱动因子对水资源利用规划管理十分必要。本文运用信息熵和均衡度、灰色关联分析模型,对江苏省用水结构的合理程度及驱动因子进行研究,并对未来水资源供需形势和用水结构演变进行预测。结果表明,2011—2020年,江苏省用水总量呈下降态势,农业用水仍占据主导地位且用水量变化不大;三大流域用水结构信息熵与均衡度同步变化,呈明显上升趋势;作物播种面积、万元工业增加值用水量、总户数、园林绿化面积分别是农业、工业、生活及其他用水变化的重要驱动因子。分析结果可为未来水资源管理与规划提供依据。

作者： DUAN WuHua zhu LiYang JING Shan zhu yongjun Institute of Nuclear and New Energy Technology Tsinghua University Beijing 102201 China Institute of Nuclear and New Energy Technology Tsinghua University Beijing 102201 China Institute of Nuclear and New Energy Technology Tsinghua University Beijing 102201 China Institute of Nuclear and New Energy Technology Tsinghua University Beijing 102201 China

The mixed trialkylphosphine oxide-nitric acid (TRPO-HNO3) complex prepared by contacting pure TRPO with concentrated HNO3 may be used as additives for direct dissolution of lanthanide and actinide ox- ides in the supercritical fluid carbon dioxide (SCF-CO2). Properties of the TRPO-HNO3 complex have been studied. Experimental results show when the initial HNO3/TRPO volume ratio is varied from 1:7 to 5:1, the concentration of HNO3 in the TRPO-HNO3 complex changes from 2.12 to 6.16 mol/L, the [HNO3]/[TRPO] ratio of the TRPO-HNO3 complex changes from 0.93 to 3.38, and the content of H2O in the TRPO-HNO3 complex changes from 0.97% to 2.70%. All of the density, viscosity and surface tension of the TRPO-HNO3 complex change with the concentration of HNO3 in the complex. The protons of HNO3 and H2O in the complex undergo rapid exchange to exhibit a singlet resonance peak in NMR spectra with D2O insert. When the TRPO-HNO3 complex dissolves in a low dielectric constant solvent, small droplets of HNO3 appear which can be detected by NMR.
