外形

• Pinyin: wài xíng
• Hanzi breakdown: 外 = 夕 + 卜; 形 = 开 (open) + 彡 (stripes/lines indicating visible form) — the visible lines that define a shape

Meaning

Outward shape; external form; silhouette. The visible geometric contour or physical outline of an object or creature.

More structural and geometric than 外表 (which encompasses overall impression) or 外貌 (which applies to people's faces). 外形 focuses on the shape and contour — the outline or silhouette that defines something's structure. Commonly used in product design, biology, architecture, and vehicle descriptions. Collocations: 外形设计 (exterior design), 外形美观 (visually appealing form), 外形相似 (similar in shape).

2. 该型无人机外形模仿鸟类，能够更好地融入自然环境，不易被察觉。 The drone's exterior form mimics a bird, allowing it to blend into natural surroundings more effectively and avoid detection.
3. 两种矿物质外形极为相似，但化学成分截然不同，初学者很容易混淆。 The two minerals look extremely similar in shape but have entirely different chemical compositions, making them easy for beginners to confuse.
