查询词典 hereditarily enumerable set

An enumerable object is typically an instance of a compiler-generated enumerable class that encapsulates the code in the iterator block and implements the enumerable interfaces, but other methods of implementation are possible.

典型的可枚举对象是由编译器自动生成的封装了迭代器块中的代码并实现了可枚举接口的可枚举类的实例，但其他的实现也是允许的。

The anlysis of UPGMA cluster among the five natural populations showed that: except the population of WY, the other populations have similar hereditarily,and the populations of TM,DH have the most similar hereditarily. 4 It suggested that the protected of natural populations should be combined with in situ and transferred because of a certain extent genetic variation among the natural populations.

通过对5个居群的UPGMA聚类分析显示：除了的亲缘关系较远之外，其他银杏居群显示出较近的亲缘关系，其中以和的亲缘关系最近(4)由于银杏不同居群间出现了相当程度的遗传分化，建议就地保护和迁地保护结合进行。

Tumorous stem yield was only significantly hereditarily positively correlated with vegetative duration, developmental duration, ratio of stem and leaf, horizontal length and whole plant fresh weight, negatively fur percentage and tumorous stem index. There were close relation and harmonies among the quantities characters that were significantly hereditarily correlated with tumorous stem yield. High yield breeding combining with strong ecological adaptability and good quality should be largely based on later maturity, tumorous stem diameter, whole plant weight and higher ratio of stem and leaf.

瘤茎产量与营养生长期、瘤茎膨大期、瘤茎横径、茎/叶、株鲜重呈极显著遗传正相关，与菜形指数、菜皮百分率呈极显著遗传负相关，与其余性状相关均未达显著水平；与瘤茎产量显著相关的性状间关系密切，有很好的协同性，分析提出茎瘤芥育种选择熟性晚、瘤茎横径大、茎/叶高和植株个体较大的品种，可实现品种产量高、生态适应性强和瘤茎品质较佳等三者的协调统一。

Firstly, we analyze the deficiencies ofexisting ones, extend domains of fuzzy logical operators from the cap product withtwo sets to them with arbitrary (finite, enumerable, or non-enumerable) number ofsets to form two general mappings so as to conform them to the fuzzy conjunctionand infimum, and to fuzzy disjunction and supremum, respectively, and fuzzify theset inclusion of fuzzy sets. Similar to the classical adjunction, the concept of fuzzyadjunction is introduced.

首先分析了原有"模糊形态学"框架的缺陷，进而将模糊合取和模糊析取算子的定义域从两个集合的笛卡儿乘积推广到任意多个集合的笛卡儿乘积，形成两个一般的映射，使得模糊合取与下确界、模糊析取与上确界保持一致，以此将模糊集的包含关系一般化。

All of the following enumerable methods are simply proxies to the Prototype enumerable method of the same name.

下面所有枚举方法是对同名的 Prototype 可枚举方法的简单代理。

Subsequent invocations of the enumerable object's GetEnumerator, if any, return a copy of the enumerable object.

以后对可枚举对象的GetEnumerator方法的调用，将返回可枚举对象的一个拷贝。

In that type of implementation, the first time an enumerable object's GetEnumerator method is invoked, the enumerable object itself is returned.

这种情况下，当可枚举对象的GetEnumerator方法第一次被调用时，将返回可枚举对象本身。

Consequently, the class PC of the plus cupping computably enumerable degrees is not an ideal of ?, the upper semilattice of the computably enumerable degrees.

因此所有加杯可计算枚举度组成的集合PC不是ε的理想，这里ε是所有可计算枚举度构成的上半格。

In section one, we introduce some background of the topic, in section two we review some basic and recent results about the structure and hierarchies of the computably enumerable degrees which are closely related to our topic- the algebraic structure of the plus cupping Turing degrees, in section three, we outline the basic principles of the priority tree argument, one of the main frameworks and tools of theorem proving in computability theory, and in section four, we prove a new result concerning the algebraic structure of the plus cupping Turing degrees that there exist two computably enumerable degrees a, b such that a, b ? PC, and the join a V b of a and b is high.

度结合为0′。本篇论文分为4个部分：第一部分介绍了这个领域的一些背景知识；第二部分主要回顾了前人在研究可计算枚举度的结构和层谱时所取得的一些基本和最新结果，这些结果与我们的主题—加杯图灵度的代数结构密切相关；在第三部分中，我们概要的描述了优先树方法的基本原理，此方法是可计算性理论中定理证明的一个重要框架和工具；第四部分证明了一个加杯图灵度代数结构的新结果：存在两个可计算枚举度a，b，满足a，b∈PC，而且a和b的并a∨b是一个高度。

For an abitrary set X, appropriate order relations on WCL (the set of all weak closure operators), WIN (the set of all weak interior operators), WOU (the set of all weak exterior operators), WB (the set of all weak boundary operators), WD (the set of all weak derived operators), WD*(the set of all weak difference derived operators), WR (the set of all weak remote neighborhood system operators) and WN (the set of all weak neighborhood system operators) can be defined respectively, which make WCL, WIN, WOU, WB, WD, WD*, WR and WN to be complete lattices that are ismorphic to CS(X,CS is the set of all closure systems on X.

证明了可以在WCL(X上的弱闭包算子的全体)、 WIN(X上的弱内部算子的全体)、 WOU (X上的弱外部算子的全体)、 WB (X上的弱边界算子的全体)、WD、 WD*(X上的弱差导算子的全体)、 WR(X上的弱远域系算子的全体)和WN(X上的弱邻域系算子的全体)上定义适当的序关系，使它们成为与CS(X，〖JX-*5[JX*5]同构的完备格其中CS(X是给定集合X上的闭包系统的全体。

After explaining total design of automated test system for microcircuit , the thesis introduces GPIB standard .
