近日，成都市金牛区某小区向业主返还物业费结余款项，引发社会关注。据报道，今年以来，济南、南 通、昆明等地也有小区将公共收益以现金或抵扣物业费的形式返还业主。小区物业费结余是否返还，与 物业服务计费方式密切相关。 根据我国《物业服务收费管理办法》，业主与物业管理企业可以采取包干制或者酬金制等形式约定物业 服务费用。包干制下，业主向物业管理企业支付固定物业服务费用，盈余或亏损均由物业管理企业享有 或承担，物业费属于企业收入，业主难以知道"钱花在了哪里"；酬金制下，预收的物业服务资金按约定 比例或数额提取酬金支付给物业管理企业，其余全部用于物业服务合同约定的支出，结余或不足均由业 主享有或承担。上述成都市某小区采取的就是酬金制，由业主委员会推动物业返还历年来物业费结余款 项给业主。 立足居民期盼，各地需进一步规范社区物业服务收费行为，切实保障业主和物业服务企业合法权益，加 快推动物业服务行业高质量发展。在物业费返还业主这一有益尝试基础上，应通过规范物业服务收费及 公共收益管理、加强服务信息公开、建立服务信用评价机制等举措，进一步提升物业管理水平及服务质 量。同时，要善用新时代"枫桥经验"，搭建公共事务协商平台，推动 ...

美国总统特朗普8月4日在社交媒体发文称，由于印度购买大量俄罗斯石油并借此获利，美国将大幅 提高对印度产品征收的进口关税。印度官员强硬回应称，印度的能源采购只考虑国家利益，不会受外部 压力影响，印度将采取一切必要措施维护国家利益和经济安全。面对美关税威胁，印度为何选择"硬 磕"？ 但是，随着美西方加大对俄罗斯石油的制裁力度，印度政府采取积极能源外交政策，通过与中东、 非洲、中亚等地区的能源富集国家建立合作关系，推动进口来源多元化，保障能源供应稳定性。除了从 俄罗斯进口石油外，2024年，中东地区原油进口占比46%。为了规避霍尔木兹海峡这一印度能源安全软 肋的潜在风险，印度增加了从美国、加拿大、哥伦比亚等美洲产油国和尼日利亚、安哥拉等西非产油国 的原油进口。特别是在贸易谈判的压力下，印度2025年前4个月自美国原油进口量增长到631万吨，价值 37.8亿美元，占印度原油总进口量的7%，2025年一季度自美国原油进口同比增长66.7%，自加拿大、哥 伦比亚等美洲国家的原油进口增幅明显，自西非、中亚等地区的原油进口保持稳定增长。 面对美国近日发出将对印度进口俄罗斯石油施加惩罚性关税的威胁，印度石油和天然气部长哈迪普 ...

人类离"新石油"时代更近了一步。7月25日，全球首次绿色船用氨燃料加注作业在大连顺利完成。 此次作业由中石化中海燃供实施，所用燃料来自远景能源在内蒙古赤峰打造的全球最大绿色氢氨项目。 从草原上的风光发电到电解水制氢，再到合成氨运输至沿海，最终注入船舶，这条跨越千里的产业链， 首次验证了绿氨燃料"端到端"的可行性，开创了绿氨替代化石能源的先河。 能源是经济社会发展的重要基础，石油则是一种普遍使用、高安全、低成本的能源。无论是人们日 常生活，还是国家经济建设和社会发展，都离不开石油。哪个国家掌控了石油，就占据了全球竞争的有 利地形，为经济稳定发展和人民生活水平不断提高提供更多保障。 由于石油资源分布不均衡和有限性，许多国家都依赖进口，石油价格和供给变化直接影响国家经济 利益和国民福利。20世纪70年代石油危机以来，各国一直在寻找可以替代石油的优质能源。人们首先想 到的是利用方便、资源丰富的光伏和风电。随着技术快速进步，风光发电成本大幅下降，在很多地区已 经具备了与化石能源竞争的实力。但风光发电"看天吃饭"，很多时候不可控，冶金、化工、重载交通等 领域也无法完全通过绿电替代来解决低碳发展问题。 当前，欧盟正加紧推动 ...

Core Viewpoint - The article emphasizes the importance of distinguishing between "old grain" (陈粮) and "aged grain" (陈化粮), clarifying that old grain is safe for consumption and meets national food safety standards, while aged grain is not suitable for consumption due to quality degradation [1][2]. Group 1: Definitions and Differences - Old grain refers to grain stored for over one year, which, despite reduced freshness, maintains good quality and meets nutritional and safety standards for food processing or animal feed [1]. - Aged grain is defined as grain that has deteriorated due to improper storage conditions or excessive storage time, leading to issues like mold and excessive aflatoxin, making it unsuitable for consumption [1][2]. Group 2: Historical Context and Improvements - The concept of aged grain emerged in the late 1990s when grain storage practices were inadequate, leading to a storage quality rate dropping to around 60% [2]. - With the implementation of a scientific grain rotation mechanism and modern storage technologies, the storage quality rate has significantly improved, with the central reserve grain storage quality rate rising to over 95% [2]. Group 3: Storage and Quality Control - Strict quality control measures are in place for both incoming and outgoing grain, including comprehensive assessments of moisture, impurities, and safety indicators, with a "one strike" policy for any non-compliance [3]. - A dynamic monitoring system is established within storage facilities, utilizing sensors and AI technology to track grain conditions and detect pest issues, ensuring immediate response to any quality concerns [3]. Group 4: Distribution and Utilization - The rotation of old grain is managed through various channels, including competitive sales on grain trading platforms and targeted supply to key food processing enterprises, ensuring quality products reach consumers [4]. - Grain nearing its expiration date is subjected to strict testing and may be repurposed for animal feed or industrial use, promoting resource efficiency and food safety [4].
