中文百科

直径

红线所指的线段是圆的直径。

在数学尤其是几何学中,直径是圆形的特性之一,是指穿过圆心且其两端点皆在圆上的线段或者该线段的长度,一般用符号d表示。

在一般的度量空间(也就是定义了距离的空间,比如说常见的二维平面)上,也可以定义一个集合的直径。在这里直径是这个集合之中两点之间的距离的最小上界:

\operatorname{diam}(X) := \sup\{d(x,y):x,y\in X\}

Relación entre la longitud de la circunferencia y el diámetro: π.

In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere. The word "diameter" is derived from Greek διάμετρος (diametros), "diameter of a circle", from δια- (dia-), "across, through" + μέτρον (metron), "measure". It is often abbreviated DIA, dia, d, or .
