1、 Solar energy

Solar energy is a clean energy source, mainly utilized through photothermal and photovoltaic methods.

Photothermal utilization

By using a collector to convert solar radiation energy into thermal energy, it is used to heat media such as water or air. Commonly found in solar water heaters, they are widely used in homes, hotels, and other places to meet the hot water needs in daily life and reduce dependence on traditional energy sources such as natural gas and electricity.

Photovoltaic utilization

Using photovoltaic cells to directly convert sunlight into electrical energy. Photovoltaic power stations are a manifestation of their large-scale applications, including ground-based photovoltaic power stations and distributed photovoltaic power generation systems. Distributed photovoltaic power generation can be installed on building roofs, etc., which can not only meet their own electricity needs, but also connect excess electricity to the grid for sale.

2、 Container

Definition and specifications

Container is a standardized large loading container. The internationally recognized standard containers come in different sizes such as 20 feet and 40 feet, with unified standards for size, structure, and strength.

Functions and Applications

Mainly used for the transportation and storage of goods. In maritime transportation, container ships can load a large number of containers to achieve efficient transportation of goods; In land transportation, goods can be transferred between ports and inland areas through container trucks. At the same time, there are also special purpose containers, such as refrigerated containers for transporting perishable goods and dry cargo containers for general cargo transportation.

3、 Transportation

type of shipping

Mainly including road transportation, railway transportation, waterway transportation, air transportation, etc. Highway transportation has high flexibility and is suitable for short distance transportation; Railway transportation has a large capacity and low cost, making it suitable for medium to long-distance freight transportation; Water transportation has low costs and large capacity, mainly used for the transportation of bulk commodities in international trade; Air transportation has fast speed and is suitable for transporting high-value and time sensitive goods or personnel.

Composition of transportation system

4、 Bridge

Bridge type

According to the structural form, it can be divided into beam bridges, arch bridges, cable-stayed bridges, suspension bridges, etc. The beam bridge structure is simple and often used for small and medium span bridges; The arch bridge has a beautiful appearance and strong load-bearing capacity; Cable stayed bridges and suspension bridges are suitable for large-span bridges, which can span wide rivers, valleys, etc.

5、 Ship

Ship type

There are various types of ships, including bulk carriers (used for transporting coal, ore, and other bulk goods), oil tankers (transporting petroleum and its products), container ships (specialized in transporting containers), and passenger ships (transporting passengers). Different types of ships have their own characteristics in terms of hull structure, power system, cargo capacity, etc.

6、 Industrial

industrial system

Covering numerous industries such as mechanical manufacturing, chemical engineering, electronics, textiles, etc. Various industries are interrelated and interdependent, together forming a complete industrial system. For example, mechanical manufacturing provides production equipment for other industries, while the chemical industry provides raw materials and chemical products.

Industrial development trend

At present, the industry is developing towards automation, intelligence, and greening. Automation and intelligent technologies can improve production efficiency and product quality, such as the application of industrial robots on production lines; Greening emphasizes energy conservation and emission reduction, adopting environmentally friendly production processes and raw materials to address environmental and resource challenges.
