Mathematical principles applied by Guang Zhouta.
Seen from a distance, Guang Zhouta is a curved surface. At close range, it is made of several straight materials.

The diameter of the ellipse at the bottom of Guang Zhouta is about 60m*80m, and the eccentricity is 1.25. The diameter of the ellipse at the thinnest part of the waist is about 20.88m*36m, and the eccentricity is 0.83 144. The eccentricity of the waist ellipse of hyperboloid should be constant, so it is not hyperboloid.

Her upper and lower ellipses not only have different centers, but also rotate relatively: "In the process of persuading experts, the engineering designer has formed an intuitive demonstration system to demonstrate the shape change law of the tower. The formation of the tower has several processes. By stretching, it changed from a cylinder to an elliptical cylinder. The elliptical column changes up and down, the lower part becomes larger, the upper part becomes smaller, and then after a little, it twists up and down 45 degrees. But the line connecting the upper and lower ellipses is perpendicular to the ground. Then the center of the upper ellipse deviates from the center of the lower ellipse 10 meter, and finally forms an asymmetric twisted waist shape to find the relationship between geometric figures. After finding this relationship, you can quickly understand any change, what it looks like, and whether it is ok for the structure.
