The technical support for the main equipment in "Cosmos Exploration Pavilion" — the clamshell celestial sphere dome.

The蚌-shaped spherical screen is designed based on the Bernoulli's principle of fluid mechanics, ensuring a reliable and safe system with diverse functionalities. Its main advantages and features include:
The opening and rotation features allow the observatory dome to offer bidirectional observation, effectively blocking ground scattered light and well-suited for astronomical observations. It primarily focuses on the celestial features of the main sky, with stars distributed in a Gaussian pattern (smaller at the bottom and larger at the top) at the zenith position.
2. The closed structure, with its smooth, round exterior and a highly reflective metal interior, can serve as the dome of an astronomy hall (and also as the screen for an IMAX cinema).
3. The transitional space can be designed as an observatory exhibit hall, featuring various astronomical phenomena models, demonstration equipment, and a multimedia broadcast studio.
