The Ziyoutun Cu-Au district is located in the Jizhong–Yanbian Metallogenic Belt and possesses excellent prospects. However, the thick regolith and complex tectonic settings present challenges in terms of detecting and decomposition of weak geochemical anomalies. To address this challenge, we initially conducted a comprehensive analysis of 1:10,000-scale soil geochemical data. This analysis included multivariate statistical techniques, such as correlation analysis, R-mode cluster analysis, Q–Q plots and factor analysis. Subsequently, we decomposed the geochemical anomalies, identifying weak anomalies using spectrum-area modeling and local singularity analysis. The results indicate that the assemblage of Au-Cu-Bi-As-Sb represents the mineralization at Ziyoutun. In comparison to conventional methods, spectrumarea modeling and local singularity analysis outperform in terms of identification of anomalies. Ultimately, we considered four specific target areas(AP01, AP02, AP03 and AP04) for future exploration, based on geochemical anomalies and favorable geological factors. Within AP01 and AP02, the geochemical anomalies suggest potential mineralization at depth, whereas in AP03 and AP04 the surface anomalies require additional geological investigation. Consequently, we recommend conducting drilling, following more extensive surface fieldwork, at the first two targets and verifying surface anomalies in the last two targets. We anticipate these findings will significantly enhance future exploration in Ziyoutun.

在求解作业车间调度问题(job-shop scheduling problem, JSP)的局部搜索算法中,构造移动执行后的邻域解严重影响了局部搜索算法的计算效率.为此,基于拓扑排序和工序最大弧数的相关理论,提出了调度解拓扑排序的划分方法,实现了邻域解拓扑排序的构造;并在邻域解的拓扑排序中,准确地识别了邻域解中头和尾时间发生改变的工序集合,从而实现了邻域解的快速、动态构造.实验结果表明:相比于目前的邻域解构造方法,所提出的邻域解的动态构造方法,在计算速度上有着明显优势,且能够显著地节省计算时间.

近年来,美元体系的供给、流通、回流以及治理机制出现了紊乱甚至失能的现象。美国量化宽松货币政策失度加剧了“新特里芬两难”,应对乌克兰危机的失策削弱了“石油美元”体系,联邦政府债务失控侵蚀了美元体系的基石,金融监管失察加剧了国际金融动荡,大国竞争战略失常则加速了去美元化进程。美元体系的边际调整具有必然性和长期性,美元体系有可能向失序、失能、失效的路径演进,全球经济则可能陷入金融风险、转型风险与政治风险相互交织的困境。广大发展中国家在短期内难以摆脱美国货币政策溢出效应的负面影响,其金融安全和可持续发展都面临前所未有的挑战。美元体系的边际调整是美国霸权式微的体现,其根源在于美国固守霸权思维、推卸国际责任、追求狭隘的安全和地缘政治利益以及缺乏大国应有的格局与气度。
