「tacnodes」是一个常用成语,以下为其拼音、释义、出处、用法、典故及例句等详细内容,供学习与查阅参考。

“tacnodes”的音标:英式/ˈtæk.nəʊd/,美式/ˈtæk.noʊd/

“tacnodes”的用法和例句8句:

  • In algebraic geometry, tacnodes are singularities where two curves meet with identical tangent lines, exhibiting higher-order contact.(代数几何中,二重切点是两条曲线以相同切线相交的奇点,表现出高阶接触。)
  • The curve defined by (y - x²)² = 0 has a tacnode at the origin, as both branches coincide and share the same tangent.(由(y - x²)² = 0定义的曲线在原点有一个二重切点,因为两个分支重合且共享同一条切线。)
  • Unlike a crunode (where two curves cross), a tacnode involves curves that touch but do not cross, with a shared tangent.(与自交点(两条曲线相交)不同,二重切点涉及相触但不相交的曲线,且共享切线。)
  • When classifying plane curve singularities, tacnodes are distinguished from nodes by their tangential contact condition.(在分类平面曲线奇点时,二重切点通过其切线接触条件与节点区分开来。)
  • The resolution of a tacnode often requires multiple blow-ups to separate the tangent branches into distinct curves.(解决二重切点通常需要多次 blow-up(吹胀)将相切的分支分离成不同的曲线。)
  • Etymologically, "tacnodes" derives from "tangere" (Latin for "to touch") and "node," highlighting the tangential nature of the singularity.(从词源学上,“tacnodes”源自“tangere”(拉丁语,意为“触摸”)和“node”,突出了该奇点的切线特性。)
  • In the study of moduli spaces of curves, tacnodes serve as important examples of non-transverse singularities.(在曲线模空间的研究中,二重切点作为非横截奇点的重要例子出现。)
  • The local ring at a tacnode reflects the higher multiplicity of intersection, distinguishing it from simpler singular points like cusps.(二重切点处的局部环反映了相交的高重数,将其与尖点等更简单的奇点区分开来。)
