定义1.2 全等(或一致性, congruence)是一个函数 Φ , 其能够将一个半度量空间 S 映射到另一半度量空间 S′ 中, 并且使得 (1.1)ρ(x,y)=ρ′(Φ(x),Φ(y)),其中x,y\in\mathbb S , \rho' 为度量空间 \mathbb S' 中的度量. 即全等是保持半度量空间之间半度量的映射. 若两个半度量空间之间存在...
而在这里使用点和点之间的两两距离也能够描述多体系统的坐标, 我们称其为距离坐标(distance coordinate), 其具有若干特点. 本系列文章大致翻译自以下文章[1], 本人水平有限, 若有问题恳请大家批评指正, 大家如果有兴趣的话可以直接查阅原文阅读. 赫连独:Distance Geometry: 距离几何与距离坐标(一)9 赞同 · 0 ...
In this tutorial, we will learn about distance formulas in two- dimensional planes and three-dimensional planes with a few solved examples.Distance Formula in Coordinate GeometryThe distance between the origin and the coordinates on the XY plane are(𝑥1, 𝑦1) & (𝑥2, 𝑦2) where 𝑃...
Lines and distance are fundamental to coordinate geometry, not to mention to the Math IC test. Even the most complicated coordinate geometry question uses the concepts covered in the next few sections. DistanceMeasuring distance in the coordinate plane is made possible thanks to the Pythagorean theor...

A coordinate-free analytical solution to the problem of registration was given by first finding an analytical solution for a least squares best fit of two slightly varying homologous point clouds and then calculating the displacement parameters by the previous derivations all directly in terms of ...
Alternately, in a coordinate plane, we can use the formula d=sqrt((x2-x1)^2+(y2-y1)^2)) How to solve using the distance formula? Using the coordinates given on any two axes, subtract the x values and square it; then subtract the y values and square it. Add the x and y valu...
Distance geometry problems (DGPs) are concerned with the construction of structures given partial information about distances between vertices. I present a generalisation which I call the angle and distance geometry problem (ADGP), in which partial angle information may be given as well. The work ...
