But classical rough set are based on indiscernibility relation or similarity relation. The problems in Seismology deal with ordering objects instead of classifying objects.

但是，经典的粗糙集理论建立在由等价关系对对象集划分的基础上，而震例数据是有序的而不是分类的对象。

The notion of weak fuzzy similarity relations,a generalization of fuzzy similarity relations,is used to represent indiscernibility of elements.

为此提出用模糊相似关系和弱模糊相似关系的概念来代替等价关系，同时引入了弱模糊相似关系的相似度概念和相似类概念，定义了基于弱模糊相似关系的广义粗糙集及标准的广义粗糙集上下近似；研究了两对上下近似算子的性质，讨论了3种粗糙隶属函数的性质并验证了它们的性质。

This paper describes a new algorithm of image enhancement of impulse noise based on PCNN time matrix and rough sets indiscernibility relation. For noisy gray images, the results of computer simulations show that the image noise can be reduced efficiently and the image becomes clear and the target details of the image can be enhanced better by using this algorithm. In addition, the effects of this algorithm are better than usual image enhancement algorithm.

基于粗集理论中的不可分辨关系的等价概念及PCNN赋时矩阵，提出了一种含有脉冲噪声的图像增强算法，计算机仿真结果表明，对被噪声污染的灰度图像，用基于PCNN与粗集理论相结合的图像增强算法处理后，图像噪声得到有效抑制，画面更清晰，图像中目标的细节也得到了很好的增强，其结果优于常规方法。

A fuzzy indiscernibility relation is changed into the indiscernibility relation by using a λ-cut in the rough approximation of decision classes, and an extension of VPRS method is proposed in which probabilistic rules are obtained from fuzzy decision tables.

为了从模糊近似空间中获取用于概率决策的规则，在决策类的粗糙近似中，通过应用λ-截集，将模糊不可分辨关系转化为等价关系，提出一种可从模糊决策表中获取概率规则的扩展变精度粗糙集方法。

In the field of x＜0.3, the breathing-mode distortions of BiO〓 octahedra create two kinds of inequivalent Bi atoms.

当x＜0.3时，BiO〓八面体的呼吸模式形变形成了两种不等价的铋原子。

The bonding properties and electronic structure of the inequivalent oxygen atoms on MoO 3 (100) and (010) crystal surfaces were studied by ab initio Hartree Fock method.

用从头计算Hartree Fock方法研究了MoO3(0 10 )和(10 0 )晶面上几种结构不等价氧的成键特征和电子结构，并考察了H+在不同氧位上的吸附性能以及吸附后形成的OH从表面脱附的性质。

It indicates that sp3 bonds have been formed between adjacent fullerene molecus via [2+2] cycloaddition reaction, leading to the inequivalent sp2 carbons on C60 cage. The former line has been broadened and has several components due to this inequivalent sp2 carbons.

这表明通过[2+2]加环反应在邻近C60分子之间形成了sp3杂化共价键，使得C60分子球笼上出现了五个位置不等价的sp2杂化碳原子，导致位于145ppm附近的sp2杂化峰展宽。

A complete set of invariants can be used to judge the equivalence of two states under LUT.

一个不变量的完全集合可以用来确定两个态在局部幺正变换下是否是等价的。

In Japan, where electricity is expensive, solar power is now fully cost-competitive with power from the grid, says Paul Maycock of PV Energy Systems, a consultancy based in Virginia.

弗吉尼亚州PV能源系统咨询公司的保罗梅科恪列说，日本的电力很贵，太阳能动力如今已完全能与电网电力等价消费。
