查询词典 conditions

In Chapter 1, we use the upper and lower solutions method, the bootstrap technique and the Schauder fixed point theorem to investigate the existence of periodic solutions and the asymptotic behavior of general time-dependent solutions for periodic reaction-diffusion systems of the following three types:(1) Quasimonotone nondecreasing system;(2) Mixed quasimonotone system;(3) A nonquasimonotone 2-system. The boundary conditions are assumed to be either the Dirichlet condition or linear Robin conditions.

在第一章，我们应用上、下解方法，bootstrap技巧和Schauder不动点定理考察如下三类周期反应扩散方程组的周期稳态解的存在性和一般的时变解的渐近性态：（1）拟单增系统；（2）混拟单调系统；（3）一个非拟单调2-系统，其边界条件是Dirichlet条件或线性Robin条件。

Compared with the same wave problems with conventional Dirichlet boundary conditions, the absorbing boundary conditions can reduce the numerical reflection on boundaries and avoid solution distortion. In addition, the central differences method is economic in memory requirement and computing time compared with implicit integral method.

结果表明：该解法在空间上具有谱精度，在时间上达到二阶精度；与第一类边界条件相比，吸收边界有效地削弱了边界上的数值反射，避免了解的失真；使用中心差分的时间积分方法同隐式积分方法相比，适合波的传播特性，避免了矩阵求逆运算，并且占用的计算机内存小。

Apparently, the approximate controllability doesn"t hold for generally linear parabolic equations with bounded control. It doesn"t hold for the semilinear heat equations presented there,either. Then, it is proved by analyzing its" solutions that no matter how long the time T is , there are targets that can"t be approximated by the solution of heat equation with Dirichlet boundary conditions;If a given target satisying certain conditions can be reached by the solution of heat equation .

本文先针对两个具体的半线性热方程系统证明了控制加约束后系统是不能控的；然后通过分析方程的解，对带位势及Dirichlet边界条件的热方程系统，无论时间多大，都存在不能控的目标；文中还证明了满足一定条件的目标可达。

If taken the firms as the organization of cooperative game and taken the group rationality and discrete conditions into consideration, the distribution, based on the Shapley value of cooperative game, can meet the individual rationality and completeness conditions, and can give a more reasonable interpretation on the sources of the real firms' economic profits and the great differences between aggregate social labor incomes.

如果将企业视为合作博弈的组织，并考虑到群体理性和离散条件，按照合作博弈的夏普莱值进行分配则能够满足个体理性和完备性条件，也可以对现实中企业经济利润的来源和社会中劳动收入之间的巨大差异给予更为合理的解释。

Foucault addresses statements only in the specific conditions of their emergence and transformation; these conditions are themselves discursive.

For the items satisfy statutory conditions, they shall give approval in written form and make announcement, while for those dissatisfy statutory conditions, they shall make a decision of disapproval in written form and give explanations.

第十三条统计调查项目的审批机关应当对调查项目的必要性、可行性、科学性进行审查，对符合法定条件的，作出予以批准的书面决定，并公布；对不符合法定条件的，作出不予批准的书面决定，并说明理由。

In this paper, the mutual relations of these additional conditions are investigated systematically and clarified. It is proved that each one of these conditions implies distributivity. Furthermore, the mutual relations of normal residuated lattices, subnormal residuated lattices, BL-algebras and sub-BL-algebras and that they are all distributive lattice are known.

本文系统研究并弄清了这些附加条件相互之间的关系，证明了它们中的每一条都蕴涵着分配性，从而知道了正规剩余格、次正规剩余格、BL-代数、次BL代数相互之间的关系，并且它们都是分配格。

The paper discusses the creation conditions and formation mechanism of enterprise clusters in detail. The three necessary conditions for clustering are technical divisibility of production process, rich opportunity of product differentiation and low transportation cost.

本文详细讨论了企业集群产生的供给条件、需求条件和社会历史条件，网络效应在企业集群形成过程中起着关键作用，地方公共产品的有效供给是集群形成和发展的重要条件。

We analyze the three conditions that Hattori has given,and then establish a new social choice function with subordinate reations,which only satisfy the condition of unrestricted domain and not the conditions of existence of a dictator and independence of influence of irrelevant individual,so as to make the social choice functions with subordinate relations more complete.

分析了Hattori给出的三个条件的合理性，并建立了一个仅满足非限制域条件而不满足存在一个独裁者与无关个人影响力独立性条件的具有从属关系的社会选择函数，使具有从属关系的社会选择函数族更加完备。
