电力系统中各种电压的变电所及输配电线路组成的整体，称为电力网。它包含变电、输电、配电三个单元。电力网的任务是输送与分配电能，改变电压。The overall system composed of various voltage substations and transmission and distribution lines in the power system is called the power grid. It consists of three units: power transformation, power transmission, and power distribution. The task of the power grid is to transmit and distribute electrical energy and change voltages.

石油化学工业，简称石油化工。一般指以石油和天然气为原料的化学工业。范围很广，产品很多。原油经过裂解（裂化）、重整和分离，提供基础原料,如乙烯、丙烯、丁烯、丁二烯、苯、甲苯、二甲苯、萘等。从这些基础原料可以制得各种基本有机原料如甲醇、甲醛、乙醇、乙醛、醋酸、异丙醇、丙酮、苯酚等。Petroleum chemical industry, abbreviated as petrochemical industry. Generally refers to the chemical industry that uses petroleum and natural gas as raw materials. The scope is very broad and there are many products. Crude oil undergoes cracking (cracking), reforming and separation to provide basic raw materials such as ethylene, propylene, butene, butadiene, benzene, toluene, xylene, naphthalene, etc. From these basic raw materials, various basic organic raw materials such as methanol, formaldehyde, ethanol, acetaldehyde, acetic acid, isopropanol, acetone, phenol, etc. can be produced.

电力工业是支撑国民经济和社会发展的基础性产业和公用事业，随着我国国民经济的快速发展和人民生活水平的不断提高，对电力的依赖程度也越来越高。电力需求与国民经济密切相关，电力弹性系数反映了用电增长速度与国民经济增长速度的相对关系。电力行业的强劲发展，也带来了管理要求的提升，管理已不再是简单的设备卡片和工作票管理，设备管理是一个系统化、完整、全面的设备全生命周期管理，管理的目的不在局限于降低成本、节省资源，更是为了提高设备利用率、延长设备使用时间，从而最终目的为企业增加效益，提高企业竞争力。The power industry is a fundamental industry and public utility that supports the development of the national economy and society. With the rapid development of China's national economy and the continuous improvement of people's living standards, the reliance on electricity has also increased. The demand for electricity is closely related to the national economy, and the electricity elasticity coefficient reflects the relative relationship between the growth rate of electricity consumption and the growth rate of the national economy. The strong development of the power industry has also brought about an increase in management requirements. Management is no longer simply the management of equipment cards and work tickets; equipment management is a systematic, complete and comprehensive equipment full life cycle management. The purpose of management is not limited to reducing costs and saving resources; it is also to improve equipment utilization and extend the service life of equipment, ultimately achieving the goal of increasing enterprise benefits and enhancing enterprise competitiveness.

交通运输行业担负着客运、货运等运输任务，在现代经济社会中显得更加重要。交通运输行业的资产主要是运动的资产和相应的场站，一般是一个公司多个线路、多个场站，运动资产、线路、场站既构成了相对的管理单元，又互相协同，完成管理、运营、维护任务。但归根结底还是围绕着运动资产（设备）来展开的，当然也包括场站的维护工作，主要的管理内容包括：点检、保养、检修、配件、线路、分站设施、装备。具体行业包括公交、物流、车站、车队、修理厂、火车站、机务段、高铁、机场、航空公司、码头、船舶、远洋运输等。The transportation industry undertakes various transportation tasks such as passenger and freight transportation, and it becomes even more crucial in modern economic society. The assets of the transportation industry mainly consist of moving assets and corresponding stations. Generally, it is one company with multiple routes and multiple stations. The moving assets, routes, and stations constitute relatively independent management units and also collaborate with each other to complete management, operation, and maintenance tasks. However, ultimately, it still revolves around moving assets (equipment). Of course, it also includes the maintenance work of stations. The main management contents include: inspection, maintenance, repair, spare parts, routes, branch station facilities, equipment. Specific industries include public transportation, logistics, stations, fleets, repair shops, railway stations, locomotive depots, high-speed railways, airports, airlines, docks, ships, and ocean transportation, etc.

港口物流是最近几年才频频出现在学术研讨和各类媒体上的新名词。港口物流是指中心港口城市利用其自身的口岸优势，以先进的软硬件环境为依托，强化其对港口周边物流活动的辐射能力，突出港口集货、存货、配货特长，以临港产业为基础，以信息技术为支撑，以优化港口资源整合为目标，发展具有涵盖物流产业链所有环节特点的港口综合服务体系。港口物流是特殊形态下的综合物流体系，是作为物流过程中的一个无可替代的重要节点，完成整个供应链物流系统中基本的物流服务和衍生的增值服务。Port logistics is a new term that has emerged frequently in academic discussions and various media in recent years. Port logistics refers to the utilization of the port's own advantages by the central port city, relying on advanced software and hardware facilities. It strengthens its radiation capacity for logistics activities around the port, highlights the port's specialties in cargo collection, inventory management, and distribution, based on the port's adjacent industries, supported by information technology, aiming to optimize the integration of port resources and develop a comprehensive port service system covering all aspects of the logistics chain. Port logistics is a special form of a comprehensive logistics system. It serves as an indispensable and important node in the logistics process, completing the basic logistics services and derivative value-added services in the entire supply chain logistics system.

光伏能源是以光伏效应为原理将太阳辐射能转换为电能。光伏能源具有无污染、无噪声、维护成本低、使用寿命长等优点，近年来得到了飞速发展。Photovoltaic energy is generated based on the photovoltaic effect, converting solar radiation energy into electrical energy. This type of energy has the advantages of being pollution-free, noiseless, having low maintenance costs, and long service life. It has experienced rapid development in recent years.
