维度 Dimension(重定向自Linear Dimensions)
维度,又称维数,是数学中独立参数的数目。在物理学和哲学的领域内,指独立的时空坐标的数目。 0维是一点,没有长度。1维是线,只有长度。2维是一个平面,是由长度和宽度(或曲线)形成面积。3维是2维加上高度形成「体积面」。虽然在一般人中习惯了整数维,但在碎形中维度不一定是整数,可能会是一个非整的有理数或者无理数。 我们周围的空间有3个维(上下,前后,左右)。我们可以往上下、东南西北移动,其他方向的移动只需用3个三维空间轴来表示。向下移就等于负方向地向上移,向西北移就只是向西和向北移的混合。

Dimension 维度(重定向自Linear Dimensions)
![]() ![]() ![]() ![]() In physics and mathematics, the dimension of a mathematical space (or object) is informally defined as the minimum number of coordinates needed to specify any point within it. Thus a line has a dimension of one because only one coordinate is needed to specify a point on it –for example, the point at 5 on a number line. A surface such as a plane or the surface of a cylinder or sphere has a dimension of two because two coordinates are needed to specify a point on it –for example, both a latitude and longitude are required to locate a point on the surface of a sphere. The inside of a cube, a cylinder or a sphere is three-dimensional because three coordinates are needed to locate a point within these spaces. |
