引入了空间曲线的整体曲率半径。这个函数与标准的局部曲率半径有关，但又有所不同，并且与曲线的各种物理上吸引人的性质有关。特别是，全局曲率半径函数提供了一个简洁的表征曲线的厚度，和某些理想的形状的结已经在DNA的背景下进行了研究。
The global radius of curvature of a space curve is introduced. This function is related to, but distinct from, the standard local radius of curvature and is connected to various physically appealing properties of a curve. In particular, the global radius of curvature function provides a concise characterization of the thickness of a curve, and of certain ideal shapes of knots as have been investigated within the context of DNA.
