序

Stochastic order and inequalities are being used at an accelerated rate in many areas, such as insurance mathematics, statistical physics,reliability theory, queue theory, etc.

随机序与不等式作为一种重要的研究方法，近年来在精算届受到了越来越多的重视。在统计学，可靠性，排队论，精算数学等研究领域，随机序都是不可或缺的决策工具。此外，在风险管理等经济学领域，随机序也为决策者提供了一种有效且可行的决策工具。

According to sequence boundary calibration, sequence boundaries were interpreted in isochronal stratigraphic frame with logging constrained inversion technology.

通过分析和比较各种序的计算机图像，得出类Walsh序更适合作为Walsh序的逆反形式的猜想。

Sequence stratigraphy provides a framework which can be used to predict the distribution of geologica l elements of reservoir forming for explorers, and in which the distribution of oil and gas has a certain disciplinarian.

层序地层学以层序为单位研究盆地充填样式、充填结构、沉积体系以及岩相在三维空间的展布，为石油地质综合研究提供了一个可预测形成油气藏的地质要素分布规律的层序格架，在这个格架中油气的分布有一定规律。

So it is assumed that the E-box might be associated with the enhancement of transcription activity.Here, the LTRs of WH17 ,DLA-25,DLA-118 and LTR with single mutation in the E-box motif were separately cloned into pCAT-Basic vector resulting in a series of recombinant plasmids containing CAT reporter under the control of different versions of LTRs.

通过对EIAV分离株WH17的LTR与L株、DA和DLA株的LTR序列进行比较，发现其在在U3-R结合处多一个E-box基序，推测该基序的变化可能会起到促进转录作用，为此将EIAV强毒株(DLA-25)、驴白细胞弱毒株(DLA-118)、EIAV分离株WH17以及U3-R结合处的E-box基序点突变的LTR分别克隆到pCAT3-basic质粒中的报告基因氯霉素乙酰转移酶的上游，获得一系列受不同LTR控制的CAT表达质粒。

The existence of the minimal and maximal fixed points for order preserving set-valued operators on semi-ordered sets and semi-ordered topological spaces was analyzed.

讨论了半序集和半序拓扑空间中保序集值算子的最小与最大不动点的存在性。

The weighted minus ordering and the weighted star ordering are both new partial ordering in morphism set.

加权减序和加权星序都是态射集中的新的偏序。

In light of the convergence theorem obtained in Chapter 2, a result on topology preservation of 2-dimensional SOM algorithm with continuous inputs is given. In Chapter 4, an equivalence relation on n dimensional Euclidean space, called equi-action relation, is introduced and a number of properties on this relation are studied.

指出了已有的有关SOM算法拓扑保序定义的缺陷，并在此基础上，给出了一个具有连续输入的二维SOM算法的拓扑保序新定义；利用第二章中的收敛性定理，我们进而获得了一个具有连续输入的二维SOM算法的拓扑保序性定理。

For the past few years, oil and gas exploration of Neogene in depression have obtained remarkable achievements and has been paid more and more attention. Therefore, the research on sequence stratigraphic framework, and tectonic control action on depositional system in syndepositional-faulted basin has great significance.

论文从层序地层格架入手，深入分析层序地层以及同沉积断裂活动对沉积体系充填的控制作用，预测储集砂体的空间分布，对陆相断陷湖盆的层序地层学研究和黄河口凹陷新近系的油气勘探具有重要的理论和生产意义。

Each node in the former order, in sequence, after the sequence number of the visit.

每个节点在前序、中序、后序中的访问的序号。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
