本文以“中国家庭金融调查”数据为样本,研究气候风险对农户金融脆弱性的影响,以及县域金融服务在缓解气候风险冲击中的传导机制。主要结论如下:(1)气候风险显著增加了农户金融脆弱性,提升县域金融机构数量及其多样性有助于缓释气候风险对农户的负面冲击;(2)提升县域金融服务能力有助于农户增加非农收入占比与金融资产比重,以应对气候风险的负面冲击;(3)异质性分析表明,气候风险仅对低收入农户的金融脆弱性存在显著影响,相比于中、高收入组,县域金融服务能力对气候风险的缓释作用在低收入农户中更大,相较于一般意义上的金融机构,增加保险类金融机构与农村金融机构数量更有利于降低农户金融脆弱性。

Main Controlling Factors and Evolution Models of Bioclastic Shoal Reservoirs of the Permian Changxing Formation in the Zhongjiang-Moxi Region

引用

Journal of Earth Science 2024年

作者： Jinhao Bai Hong Liu Song Tang Benjian Zhang Xia hua Dong Wang ying Yang Lei Tan Sichuan Provincial Key Laboratory of Natural Gas Geology， Southwest Petroleum University Southwest Petroleum University， Division of Key Laboratory of Carbonate Reservoirs，CNPC School of Geoscience and Technology， Southwest Petroleum University Central Sichuan Oil & Gas Field of PetroChina Southwest Oil & Gas Field Company PetroChina Southwest Oil and Gas Field Company Exploration and Development Research Institute

The Upper Permian Changxing Formation in the Sichuan Basin has been a consistent hotspot for natural gas exploration. Previous studies of this formation focused on the platform-margin reef areas in the northeastern Sichuan Basin but rarely dealt with the main controlling factors of the reservoirs inside the platform. Here， taking the Changxing Formation in the Zhongjiang-Moxi region in the central Sichuan Basin as an example， the characteristics and main controlling factors of the bioclastic shoal reservoirs inside the platform are systematically analyzed via core observations， rock thin-section identification， well logging analyses， and three-dimensional seismic interpretation. The results show that， in the study area， the Changxing Formation primarily develops porous reservoirs of bioclastic limestone， with the storage space dominated by intragranular and intergranular dissolution pores and typical facies-controlled characteristics. The development degree of the reservoirs is mainly controlled by contemporaneous–penecontemporaneous karstification. Specifically， the thickness and stacking style of the reservoirs are determined by the multi-order sea level change cycles; the early exposure dissolution degree of the shoal reservoirs is further controlled by micro-paleogeomorphological differences， and the reservoirs are clearly improved by dolomitization. Accordingly， two evolution models of the Changxing Formation reservoirs inside the platform in the study area are established.

Highly Hydrolysis-Resistant Polyimide Fibers Prepared by Thermal Crosslinking with Inherent Carboxyl Groups

引用

Chinese Journal of Polymer Science 2024年第2期42卷 247-255,I0010页

作者： Can-Can Zhang Jun-Long Yang Ya-Jiang huang Guang-Xian Li College of Polymer Science and Engineering State Key Laboratory of Polymer Materials Engineering of ChinaSichuan UniversityChengdu610065China

Easy hydrolysis in alkaline environments limits the use of polyimide fibers in environmental protection. The hydrolysis resistance levels of polyimide fibers can be improved by crosslinking of the macromolecular chains. In this work, crosslinked polyimide fibers(CPI fibers) were produced by intrinsic carboxyl decarboxylation for the first time. The thermal stability of the polyimide fibers containing the intrinsic carboxyl groups(PIC fibers) was studied, and the temperature of the decarboxylation-crosslinking reaction was determined to be 450 ℃. The PIC fibers were hotdrawn to initiate thermal crosslinking of the carboxyl groups and molecular chain orientation at high temperature. The CPI fibers had high tensile strengths(0.72-1.46 GPa) and compressive strengths(401-604 MPa). The oriented macromolecules and chemically crosslinked structure improved the tightness of the molecular chains and endowed the CPI fibers with excellent hydrolytic resistance. The CPI-50 fiber did not dissolve in a 0.5 wt% NaOH solution during heating at 90 ℃ for 10 h, and the tensile strength retention reached 87% when treated in 0.5 wt% NaOH solutions at 90 ℃ for 1 h, providing a guarantee for its application in alkaline corrosive environments.
