易混淆词
parameter
EN: 'Parameter' refers to a variable or limiting factor (e.g., in math or computing); 'perimeter' refers to the outer boundary or its total length.
zh: 'Parameter'(参数)指变量或限制因素(例如在数学或计算机领域);'perimeter'(周长/边界)指外边界或其总长度。
circumference
EN: 'Circumference' specifically refers to the perimeter of a circle or other curved shape; 'perimeter' is the general term for the boundary of any shape.
zh: 'Circumference' 特指圆或其他曲线形状的周长;'perimeter' 是任何形状边界的通用术语。
拼写提示
EN: Do not confuse 'perimeter' (boundary) with 'parameter' (a variable or limit). The prefix 'peri-' means 'around,' which can help you remember it relates to the outer edge.
zh: 不要将 'perimeter'(边界)与 'parameter'(变量或限制)混淆。前缀 'peri-' 意为“周围”,这有助于你记住它与外边缘有关。
