链

Heisenberg XX open chain is very important in the study of quantum state transition.

Heisenberg 开链对研究量子态在自旋链上的传递有重要的意义。

The total RNA was extracted from spleen of Xiphophorus helleri which had been immunized for two weeks. The core sequence was amplified by RT-PCR. The cDNA end sequences were amplified by RACE, and then the full-length cDNA of sIgM heavy chains gene were obtained by putting all of them. The full-length sequence contains the immunoglobulin signature sequence: FKCIANH.

以免疫两周的剑尾鱼为材料，提取脾脏总RNA，通过逆转录－聚合酶链式反应扩增出分泌型免疫球蛋白M(secretory immunoglobulin M， sIgM)重链基因的核心序列，再应用3'和5'快速扩增cDNA末端方法扩增其末端序列，拼接后获得剑尾鱼sIgM重链全长cDNA序列。

Coenzyme Q10 widely exists in each kind of histiocyte in particular in mitochondrion of the cardic muscle cell, is one kind of important active enzyme in cardic muscle cell, react as electron transfer system in breath-chain of mitochondrion, and is a important part in breath-chain, participates in ATP synthesis.

辅酶Q_(10)广泛存在于各种组织细胞尤其是心肌细胞中的线粒体中，是组织细胞内具有重要作用的活性酶，在细胞线粒体呼吸链即电子传递系统中起递氢体作用，是细胞呼吸链的重要组成部分，参与ATP的合成。

The present paper presents the chain recurrent set with the expansive homeomorphism and shadowing properties and this connection for the mistake in literature [1] and its proof.

给出具有跟踪性可扩同胚的链回归集的几个性质，指出以往文献中证明链回归集无环性时的错误之处，并给出严格的证明。

In this paper, the following statements were proved: is chaintransitive if and only if is chaintransitive; if a homeomorphism is a Lipschitz map, then has the average shadowing property if and only if has the average shadowing property.

设是紧致度量空间，：X→X是连续的，n为任一给定的正整数，证明了：是链可迁的当且仅当是链可迁的；若同胚是Lipschitz映射，则有平均跟踪性当且仅当有平均跟踪性。

SPNAnalyzer software system has a very friendly man-machine interaction interface, so the visualized modeling of stochastic Petri net is very intuitional and convenient. The response and handling of the Windows messages is extended to the graph tool module, so it is very easy to maintain. The class design of the element object module and the graph tool module guarantees the expansibility of the system. The crucial technologies including the reachability set algorithm of the stochastic Petri net model, the constitution of the homogeneous Markov chain, and the computation of the steady state probability are implemented. The design of the data structure adopts the linked list, so the execution of the algorithms is very efficient.

SPNAnalyzer软件系统具有非常友好的人机交互界面，使可视化的随机Petri网建模变得非常直观方便；将各种Windows消息的响应和处理延伸至图形工具模块，使系统的维护变得容易；元素对象模块和图形工具模块的类的设计使系统的可扩展性很好；实现了随机Petri网模型的可达集生成算法和同构马尔可夫链的构造及其稳定状态概率的求解等关键技术；数据结构的设计采用链表的形式，使各种算法都具有较高的执行效率。

The influences of horizontal merger on upper suppliers and the profit of the whole supply chain were investigated,and the effects of the power structure within a supply chain during horizontal merger were analyzed.

研究了在Cournot市场竞争条件下，生产企业的横向并购对于上游供应商和整条供应链利润的影响，以及供应链权力配置在并购中的效应。
