同余的

Further some equivalent conditions for a trivial algebra are given, and that the mapping which maps the subset of the universal to the maximal congruence that saturates the subset being a -homomorphism, being order preserving, being constant mapping, the algebra being trivial are equivalent is proved.

最后利用该同余给出了关于平凡代数的几个等价条件，证明了泛代数的子集到渗透该集的最大同余的映射为保序映射、该映射为-同态、该泛代数平凡等是等价的。

In a method for retrieving sequences having a minimum PAPR in an OFDM (orthogonal frequency division multiplexing) system, by using characteristics in which all sequences of the OFDM system are classified into cosets having the same PAPR, PAPRs of sequences in which early two elements are fixed as '0' are calculated. A sequence having a minimum PAPR is selected from among the calculated PAPRs, and sequences allocated to the coset in which the selected sequence is included are retrieved as sequences having the minimum PAPR.

It introduces the concept of power semigroup, studies the relations between homomorphism and congruence of power semigroup and obtains some perfect results.

给出了幂半群的概念，研究了幂半群的同态与同余关系，讨论了它们之间的关系，并得到了一些理想的结果。

By using congruences on a Clifford semigroup, we get that, in general, the operator is not a ∩-homomorphism.

利用Clifford半群上的同余刻画，得到了该运算不是一个∩-同态。

In chapter three, in order to distinct N 0?matrices that defined by deferent references, we will use the following notions. A matrix is called N_0~2-matrix if the matrix is nonpositive and its all-principal minors are nonpositive.

不可约矩阵Perron余的Perron向量同原矩阵Perron向量有着继承性，另外非负矩阵的Perron余也可用于Perron根的估计，因此非负矩阵的Perron余的研究有着重要的理论价值。

Two major linear random number generators, the linear congruential generator and the multiple recursive generator, have been widely studied and used for many decades. Nowadays, as the price decreasing of computer processors, parallelization of the generators is being concerned for, at least, the computational efficiency purpose.

线性同余法（linear congruential generator，LCG）与k阶乘余法（multiple recursive generator，MRG）至今仍为乱数产生器常使用的两大线性方法；而近日，由於电脑处理器成本下降，平行化计算因而被广泛研究与使用，以改善因分析与模拟资料量与日俱增，电脑运算效率降低之问题。

A Green's relation of the a dditive redect of an idempotentsemiring S is a congruence of the semiring S, but Green's relation of the multiplicative redect of S need not be.

幂等元半环S的加法半群上的Green关系是半环S的同余，然而S的乘法半群上的Green关系未必是S上的同余。

As we well known, the relation between the ideal and congruence of ring is one to one. The skew-ring congruence of regular semiring and qusi-regular semiring are characterized by using of a class of special ideals of semirings and a construction method of regulal subdirect product of regular semirings is given by using of a special mapping on semirings is also studied in this paper.

众所周知，环的理想和同余之间是一一对应的，受此启发，本文利用半环的一类特殊理想刻划了正则半环与拟正则半环上的skew-环同余，并利用半环上的一个映射给出了正则半环的正则次直积的一种构造。

In a method for retrieving sequences having a minimum PAPR in an OFDM (orthogonal frequency division multiplexing) system, by using characteristics in which all sequences of the OFDM system are classified into cosets having the same PAPR, PAPRs of sequences in which early two elements are fixed as '0' are calculated.

在一种用于在OFDM通信系统中恢复具有最低PAPR的序列的方法中，通过利用在其中将OFDM系统的所有序列分成具有相同PAPR的同余类序列的特性，计算两个开始项被固定为&0&的序列的PAPR，在所计算的PAPR中选择具有最小PAPR的序列，并且恢复分配至在其中包含所选同余类序列的序列作为具有最小PAPR的序列。

We also prove that the lattice of group congruences on a regular semigroup is isomorphic to the lattice of its full admissible subsemigroups.

另外，还证明了正则半群的群同余格同构于它的完全容许子半群的格。

It seems likely that Kraft will return with a better offer.

看起来卡夫要重新考虑一个更好的出价了。

But he'd rather burn off my feelers and watch me squirm.

可他却放任那个家伙对我为所欲为！
