集合

The concepts and characterization of fuzzy and rough sets are presented in this paper.

介绍了模糊集合及粗糙集合的概念和特征。

Hence morphisms do not so much map sets into sets, as embody a relationship between some posited domain and codomain.

不象映射一个集合的元素到另外一个集合，它们只是表示域和陪域间的某种关系。

However, in some applications, for performance and other reasons, it is feasible to transpose the data structure into a collection of lists, where an item of the collection is a list of values for a given column.

然而，在一些应用中，性能和其他原因，是可行的转成一个列表，集合中的数据结构，一个集合项目是一个给定值的列列表。

In American usage, a collective noun takes a singular verb when it refers to the collection considered as a whole,as in The family was united on this question.

在美国用法中，集合名词在指代的集合名词作为一个整体时，谓语动词要用单数形式，如在全家在这个问题上达成一致。

The token colure aggregation can make one token signify many kinds of resources, and the original place can only signify a kind of resource, expand the content of token represented, the movement color aggregation of transition can show the association condition that the more complicated events is happened at the same time.

托肯色彩集合可使一个库所的托肯表示多种资源，而原来的库所只能表示一种资源，扩大了托肯所代表的内涵，同时变迁的动作色彩集合也可表示更加复杂的事件发生的组合条件。

Based on a formal analysis of lifting decomposition, the hierarchical structure concept of the decomposition set, as well as the lifting decomposition technique of the polyphase matrix' greatest mth-order common divisor, is proposed to conquer the difficulties in the practical computation of and the optimal search in the huge decomposition set.

本文在形式化分析Lifting分解原理的基础上，提出了分解集合的分级结构概念以及多相矩阵的m阶最大公因子Lifling分解技术，克服了分解集合求解问题的高复杂性所带来的实际计算与搜索困难；进一步地，从数值稳定性及计算代价两方面研究了分解的评价问题，设计出两种实用的分解稳定性准则；最后，结合分级结构技术提出一种最优分解算法。

Both the MWZC set with ideal intra-group correlation properties and its combination sets of specific subsets can achieve the theoretical bound as long as a complete complementary sequence set with subsequence length 1 is used a basic kernel.

而且，无论是MWZC序列集合还是它的特定子集组成的合并集合都可以达到理论界限，从而在给定相关性能和序列长度的条件下，可以获得最大的序列数目。

Based on the conditional rough entropy theory, the definition of the conditional rough entropy of set is given and it can measure the uncertainty of set. The properties and the related theorems are given.

基于知识的条件粗糙熵理论，提出了集合的条件粗糙熵概念，用来刻画和度量集合的不确定性。

The theory significance of conditional rough entropy in decision information system is discussed. The conditional rough entropy measures the partial uncertainty in decision information systems.

讨论了集合的条件熵在目标信息系统中的理论意义，集合的条件熵刻画了目标信息系统的局部的不确定性。

The Engine partitions all the equations into sets according to the conditional statement in the models, whose value will be used to assemble the equations dynamically to describe the state of the system.

引擎根据模型中的条件语句，将方程分为若干集合，依靠条件语句的真值来动态组合方程集合，描述不同情况下系统的状态。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
