圆形

• Pinyin: yuán xíng
• Hanzi breakdown: 圆 = 囗 + 员 (enclosure + round vessel — a round container, hence circle/round); 形 = 开 + 彡 (spread/open + three strokes indicating shape/form)

Meaning

Circular shape; circle; round form. A geometric shape that is perfectly round, or an object or space characterised by this shape.

圆形 is the general term for a circular shape, broader than 圆 (circle as a mathematical object). Used in geometry, design, architecture, and everyday description. 圆形广场 (circular plaza), 圆形剧场 (amphitheatre/circular theatre), and 圆形建筑 (circular building) are common compounds. In Chinese cultural symbolism, circular shapes are associated with completeness, harmony, and heaven (天圆地方 — heaven is round, earth is square).

Examples

1. 古罗马竞技场的圆形结构兼顾声学、视线和受力，至今仍影响现代体育场设计。 The circular structure of the ancient Roman arena balanced acoustics, sightlines, and load-bearing, and it still influences modern stadium design today.
2. 在中国传统宇宙观中，圆形象征天的完整与永恒，天坛建筑群便体现了这一观念。 In traditional Chinese cosmology, the circle symbolizes the completeness and eternity of heaven, and the Temple of Heaven complex reflects this idea.
3. 现代城市中的圆形交通节点能减少冲突点、提高通行效率，但推广时常遇到驾驶习惯阻力。 Circular traffic nodes in modern cities can reduce conflict points and improve traffic flow, but their spread often faces resistance from driving habits.
