针对传统气凝胶纤维后处理操作复杂、加工不稳定等问题,且为有效集成纳米气凝胶与纳米纤维功能和结构优势,本文围绕新型气凝胶复合纳米纤维成形与结构调控的关键难题,利用溶液喷射同轴纺丝技术将聚丙烯腈(PAN)与SiO_(2)气凝胶通过一步法制备PAN/SiO_(2)气凝胶复合纳米纤维,研究了复合纳米纤维中SiO_(2)气凝胶质量浓度对纤维形态结构、稳定性、孔径分布、隔热性能的影响。结果表明:所制备的PAN/SiO_(2)气凝胶复合纳米纤维形态结构上呈三维卷曲状,SiO_(2)气凝胶的引入使纤维表面形成多孔褶皱型结构,且纤维表面的微孔、介孔含量随SiO_(2)气凝胶质量浓度的增加逐渐增多;该气凝胶复合纳米纤维具有优异的隔热性能,当SiO_(2)气凝胶质量浓度为6 mg/mL时,PAN/SiO_(2)气凝胶复合纳米纤维在40℃的导热系数低至0.03738 W/(m·K),未来在服用保暖、工业隔热、军用热红外屏蔽等方面具有广阔的应用前景。

The Nanling belt in South China has considerable resources of tungsten polymetallic commodities and is one of the most important metallogenic belts in the world. Data-driven weights-of-evidence （WofE） and fuzzy logic models are used to evaluate the tungsten polymetallic potential of the Nanling belt. Initially, seven ore-controlling factors derived from multi-source geospatial datasets （e.g., geological, geochemical, and geophysical） are used for data integration in the two models. Two mineral potential maps are generated that efficiently predicate the locations of the deposits. The WofE map predicate 81% of the deposits within 13.6% of the study area, whereas the fuzzy logic map predicate 81.5% of the deposits within 13% of the area. The predictive maps are syntheses of spatial association rules, which provide better understanding of those factors that control the distribution of mineralization and trigger eventual exploration work in new areas. Subsequently, in order to evaluate the success rate accuracy, the receiver operating characteristic curves and area under the curves （AUCs） for the two potential maps are constructed. The results show that the AUCs for the WofE and fuzzy logic models are 0.775 7 and 0.840 6, respectively. The higher AUC value for the fuzzy logic model implies that it delineate a greater number of favorable areas compared with the WorE model. Overall, the capabilities of both models for correctly classifying areas with existing mineral deposits are satisfactory.

关键词： weights-of-evidence fuzzy logic data integration mineral potential assessment receiver operating characteristic (ROC) curve.
