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。

In order to overcome this difficulty,a clustering algorithm based on dynamic division of connected graph is proposed.

当前大部分的聚类算法都难以处理任意形状和大小、存在孤立点和噪音以及密度多变的簇，为此，文中提出了一种基于连通图动态分裂的聚类算法。

It was observed that the Pt 4f binding energies in the same-sized Pt nanoclusters modified with alkylamine, alkylthiol, PVP, PVA or PPh〓 increase by 0.5-0.8eV relative to those of bulk Pt.

观察到具有相同金属尺寸的Pt金属内核而外层配体分别为长链胺、长链硫醇、PVP、PVA或PPh〓的纳米簇的Pt 4f电子结合能相对于块体Pt样品升高了0.5-0.8eV。

Scented plants can also evoke memories. Some annuals with good scents are sweet alyssum, the large flowering tobacco "Nicotiana Sylvestris", the Regal Lily, which flaunts clusters of trumpet-shaped white flowers, and velvety purple heliotrope.

芳香的植物同样能唤起回忆，一些一年生植物有很好的香味，比如香雪球，大片花叶烟草植物：美花烟草，花攒锦簇，随风摇曳的白色"帝王百合"，和像天鹅绒般的紫色"青莲"。

The study of 9－12 indicate that it is easy to get polyoxomolybdate with organic amine at weak acidity conditions when there are organic amine and organic acid in the same reaction systems.

化合物 9－12 的研究结果表明，在弱酸性条件下，同时存在有机酸和有机胺时，易形成含有机胺的钼氧簇，而有机酸不易进入产物晶相。

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.
