電力系統中各種電壓的變電所及輸配電線路組成的整體，稱為電力網。它包含變電、輸電、配電三個單元。電力網的任務是輸送與分配電能，改變電壓。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.

石油化學工業，簡稱石油化工。一般指以石油和天然氣為原料的化學工業。范圍很廣，產品很多。原油經過裂解（裂化）、重整和分離，提供基礎原料,如乙烯、丙烯、丁烯、丁二烯、苯、甲苯、二甲苯、萘等。從這些基礎原料可以制得各種基本有機原料如甲醇、甲醛、乙醇、乙醛、醋酸、異丙醇、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.

電力工業是支撐國民經濟和社會發展的基礎性產業和公用事業，隨著我國國民經濟的快速發展和人民生活水平的不斷提高，對電力的依賴程度也越來越高。電力需求與國民經濟密切相關，電力彈性系數反映了用電增長速度與國民經濟增長速度的相對關系。電力行業的強勁發展，也帶來了管理要求的提升，管理已不再是簡單的設備卡片和工作票管理，設備管理是一個系統化、完整、全面的設備全生命周期管理，管理的目的不在局限于降低成本、節省資源，更是為了提高設備利用率、延長設備使用時間，從而最終目的為企業增加效益，提高企業競爭力。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.

交通運輸行業擔負著客運、貨運等運輸任務，在現代經濟社會中顯得更加重要。交通運輸行業的資產主要是運動的資產和相應的場站，一般是一個公司多個線路、多個場站，運動資產、線路、場站既構成了相對的管理單元，又互相協同，完成管理、運營、維護任務。但歸根結底還是圍繞著運動資產（設備）來展開的，當然也包括場站的維護工作，主要的管理內容包括：點檢、保養、檢修、配件、線路、分站設施、裝備。具體行業包括公交、物流、車站、車隊、修理廠、火車站、機務段、高鐵、機場、航空公司、碼頭、船舶、遠洋運輸等。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.

港口物流是最近幾年才頻頻出現在學術研討和各類媒體上的新名詞。港口物流是指中心港口城市利用其自身的口岸優勢，以先進的軟硬件環境為依托，強化其對港口周邊物流活動的輻射能力，突出港口集貨、存貨、配貨特長，以臨港產業為基礎，以信息技術為支撐，以優化港口資源整合為目標，發展具有涵蓋物流產業鏈所有環節特點的港口綜合服務體系。港口物流是特殊形態下的綜合物流體系，是作為物流過程中的一個無可替代的重要節點，完成整個供應鏈物流系統中基本的物流服務和衍生的增值服務。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應為原理將太陽輻射能轉換為電能。光伏能源具有無污染、無噪聲、維護成本低、使用壽命長等優點，近年來得到了飛速發展。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.
