反对称性

A preorder that is antisymmetric is a partial order .

满足反对称性的预序关系称为偏序关系。

Based on global coupling, a method which can induce both synchronization and anti-synchronization by constructing coupled chaotic system with identical antisymmetric chaotic systems was presented.

提出在具有反对称性的等同混沌子系统中，利用全局耦合实现同步与反同步共存的一般方法，论证了其在离散系统和连续系统上的适用条件。

It is difficult to judge a transitive binary-relation by using the definition of transitivity of binary relation directly.

0引言定义在某一集合上的二元关系具有自反性、反自反性、对称性、反对称性以及传递性等性质。

In this paper, we first propose an incomplete preference in which the anti- symmetry may not hold,and then obtain many maximal element theorems with respect to incomplete preference.

为解决上述问题，我们首先提出了不要求反对称性的不完全偏好，在此基础上我们获得了许多不完全偏好意义下的极大元定理。

We start by considering the wavefunction, ignoring the antisymmetry requitement.

我们先考虑波函数，而暂不顾及它的反对称性要求。

The multi-wavelets functions are supported on [-1, 1], and one wavelet function is symmetric, the other is anti-symmetric.

所以，可以由这两个尺度函数构造一类多小波函数，这类多小波函数不但在[-1，1]上具有紧支撑性，而且一个小波函数具有对称性，另一个小波函数具有反对称性，因此这种紧支撑多小波函数适用于区间[0，1]。

But in practice compactly supported wavelet bases except Harr function are not symmetry or antisymmetry, and this will cause distortion for signals decomposition and reconstruction.

由于实际中所用到的具有紧支集的正交小波一般不具有对称性或反对称性，对于信号的分解与重构会造成失真，为解决此问题又研究了双正交小波和小波包。

Based on English definition of the six properties which a relation R defined on a set A and utilizing the logical characteristic of implications, two aspects of ordered-pair and the matrix MR are considered, and the properties of the R is analyzed one by one. A few useful conclusions are summarized as determining the properey of the R. The following collections are also analyzed between reflexive and irreflexive, symmetric and antisymmetric, symmetric and asymmetric and among irreflexive, antisymmetric and asymmetric.

根据定义在一个集合A上的关系R的六个性质的英文定义，利用蕴含式的逻辑特点，从有序对和关系R的矩阵M两个角度对每个性质逐一进行分析，得出在判定关系R的性质时可用的结论，并且分析了自反性与非自反性之间、对称性与反对称性之间、对称性与非对称性之间、非自反性和反对称性以及非对称性之间的联系。

According to the edge detection theory based on modulus maxima of wavelet transform, an infinitely differentiable wavelet with good antisymmetry was deduced to extract the edges of defects from X ray spot weld inspection images.

基于小波模极大值边缘检测原理，推导出一类具有良好反对称性的无限光滑小波并运用于点焊缺陷的边缘提取。实验表明，该方法能有效地提取缺陷边缘，并能获得较好的效果，从而为小波理论在工业 X射线无损检测中的应用作了初步探

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.

Lugalbanda 是神和被崇拜了一千年多 Uruk古埃及喜克索王朝国王。

I am coming just now,' and went on perfuming himself with Hunut, then he came and sat.

我来只是现在，'歼灭战perfuming自己与胡努特，那麼，他来到和SAT 。
