曲率

曲线 C 在 P 点的密切圆和曲率半径

曲率,符号以Kappa:κ表示,是几何体不平坦程度的一种衡量。平坦对不同的几何体有不同的意义。

曲率半径,符号以Rho:ρ表示,是曲率的倒数,单位为米。

对于平面曲线 C,在一点P的曲率大小等于密切圆半径的倒数,它是一个指向该圆圆心的矢量。其大小可用屈光度(dioptre)衡量,1屈光度等于1(弧度)每米。此密切圆的半径即为曲率半径。

密切圆的半径越小,曲率越大;所以曲线接**直的时候,曲率接近0,而当曲线急速转弯时,曲率很大。

直线曲率处处为0;半径为r的圆曲率处为1/r

若曲线  y = f(x)\, 其曲率为

对于一个以参数化形式给出的平面曲线c(t) = (x(t),y(t))\, 其曲率为

Animations of the signed curvature and the acceleration vector

In mathematics, curvature is any of a number of loosely related concepts in different areas of geometry. Intuitively, curvature is the amount by which a geometric object such as a surface deviates from being a flat plane, or a curve from being straight as in the case of a line, but this is defined in different ways depending on the context. There is a key distinction between extrinsic curvature, which is defined for objects embedded in another space (usually a Euclidean space) – in a way that relates to the radius of curvature of circles that touch the object –, and intrinsic curvature, which is defined at each point in a Riemannian manifold. This article deals primarily with the first concept.
