常见错误

❌ 错误:This object is tetrahedron.
✓ 正确:This object is tetrahedral.

错误:误用名词'tetrahedron'作为形容词。正确:应使用形容词'tetrahedral'来描述形状。

❌ 错误:It has a tetrahedral of four sides.
✓ 正确:It has a tetrahedral shape with four triangular faces.

错误:表达不准确,'tetrahedral'本身是形容词,不能直接接'of'。正确:应明确描述为四面体形状,并说明有四个三角形面。

近义词辨析

pyramidal

'pyramidal'通常指金字塔形,底面为多边形,侧面为三角形,而'tetrahedral'特指四面体,所有面都是三角形,更强调几何对称性。

A square pyramid is pyramidal, but a tetrahedron is strictly tetrahedral with four equilateral triangles.

four-sided

'four-sided'泛指任何有四条边或四个面的形状,如四边形,而'tetrahedral'专指三维空间中的四面体,具有四个三角形面。

A rectangle is four-sided in 2D, but a tetrahedron is tetrahedral in 3D with triangular faces.
