代数簇

By decomposing this algebraic variety . an algorithm to decide this problem is given.

通过代数簇的分解，给出了判定这一问题的算法。

Then, to decide whether a propositional formula can be deduced from a finite set of such formulas,we only need to decide whether the polynomial vanishes on an algebraic variety which is related to this formula set.

从而判定一个命题公式能否以一组命题公式推出，我们只需判定某一多项式是否在一代数簇上消失。

A polynomial system PS over the rational number field is constructed from the formula...,in a given many-valued logic system such that follows from ...,iff the algebraic variety defined by PS is empty, iff the idealenerated by PS is trivial.

由给定的多值逻辑系统中的一组公式，。。。，，出发，构造出了一组有理数域上的多项式PS，使得是，。。。，的逻辑结论，当且仅当PS定义的代数簇为空集，当且仅当PS生成的理想是平凡理想。

In chapter 3, we discuss several problems on piecewise algebraic varieties.

第三章我们讨论了分片代数簇的某些问题。

If cohomology with integer coefficients is used, so that

它在霍奇的著述的一个结果中出现，他在1930至1940年间通过包含额外的结构丰富了德拉姆上同调的表述，这种结构出现于代数簇的情况。

In this thesis, we mainlystudy some problems on approximate implicitization and piecewise algebraic varieties.

本文主要针对参数曲线曲面的近似隐式化和分片代数簇的某些问题展开研究。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
