查询词典 isotopic

If a loop is isotopic to a group, then it is isomorphic to that group and thus is itself a group.

如果一个圈与某个群同痕，那么它与此群同构，因此也为一个群。

Two quasigroups are ''' isotopic ''' if there is an isotopy between them.

两个拟群是'''合伦'''的当且仅当它们之间存在合伦映射。

The authors discuss a special case here, namely the case of plannar isotopy. The main part of this paper gives two algorithms to determine whether two given knot/link diagrams are planar isotopic or not, and also compares them.

本文讨论了一种特殊情形下的得分类，即平面合痕下的等价分类问题，重点介绍了两种判断两个纽结图是否是平面合痕的算法，并对它们进行了比较。

In this 'lithification' process, the originally precipitated phases undergo dissolution, reprecipitation, and isotopic re-equilibration with ambient pore fluids.

在这个所谓的岩化过程，最初沉淀的沉积物经历了溶解，再沉淀，与周围孔隙中的流体进行的同位素再平衡分馏等过程。
