Abstract： An urban overpass and its construction method, in the fields of traffic science, traffic rules, traffic engineering, and technical management. After studying the 3D mathematical model of transportation and examining the construction of urban transportation facilities in Beijing in recent years, the inventor proposed an optimized combination scheme for the transportation system of mega cities; The present invention provides a highly optimized and economical design and construction scheme for overpasses based on the characteristics of urban transportation. The scheme effectively reduces traffic flow and pedestrian vehicle intersections, improves exchange rates, has road buffering and high applicability capabilities, and is suitable for upgrading and renovating large flow complex traffic nodes such as intersections and five forks. While improving performance, it can also reduce the overall complexity of transportation facilities. The present invention only requires partial modifications to existing urban roads and overpasses, reducing the difficulty of implementation and is one of the important combination solutions for improving urban congestion.

Abstract： This article describes another important driving force behind the Earth’s atmosphere and climate change; In addition to the geological activities of the Earth itself and foreign substances such as meteorites and comets, light gases and liquid water on Mercury and Venus are also important sources. This article only uses the basic knowledge of astronomy, basic physics, and chemical concepts to analyze how water and some gaseous substances in the Earth’s orbit reach the Earth under the action of the solar wind. It also analyzed how the light gas and liquid water on Mercury and Venus were transferred to Earth. The mechanism by which ecological atmospheres appear in stellar systems similar to the solar system was analyzed.
