On the condition that nonlinear function are bounded. By using the linear matrix inequality, a sufficient condition of the output feedback stability about the nonlinear uncertain systems with time-delay is obtained and then the design method of its robust stability is also given in it.

在非线性不确定性满足增益有界条件下，利用线性矩阵不等式方法给出了鲁棒镇定律的存在条件及镇定律存在时相对应的控制器设计方法。

The purpose of this paper is to prove the existence of non-oscillatory solutions to second-order neutral time-lag differential equation with positive/negative coefficient by using contraction-image principle through defining an operator from a bounded,closed,and convex subset into Banach space.

通过定义有界闭凸子集到B anach空间上的一个算子，应用压缩映像原理讨论了带有正负系数的二阶中立型时滞微分方程非振动解的存在性，得到该方程非振动解存在的一个充分条件。

Under some reasonable assumptions of the'Distribution Matrix', the Riemann Problem with piecewise constant initial data is proved to have a unique Riemann Solver; furthermore, using'Wave Front Tracking Method'and properties of the'Generalized Characteristics', we prove the existence of weak entropy solution to the Riemann Problem with arbitrary initial data of bounded Total Variation.

在"分布矩阵"满足合理的假设前提下，证明了具有分片常值初始条件的黎曼问题的黎曼解算子的存在唯一性；并进一步运用"波前追踪法"和"广义特征"等得到了具有任意有界全变差初值条件的广义黎曼问题的弱熵解的存在性。

We know that our existence is the value of the existence of vast numbers of users,全身心for customer service is our bounden duty.

Secondly, according to the stem and leaf anatomy, leaf epidermis, pollen morphology and floral development, it is found that there are no close relations between Acorus and Typhales, especially in the aspect of floral development. In the course of floral development of A. calamus, neither bracteloe primordium nor common primordium occurs in the whole course. Early development of the flower is strongly unidirectional. Three shield carpels develop into a pistil. In Sparganium fallax, each female flower has a bracteole. The bracteole primordium and the floral primordium originate from a complex structure. A single saccate carpel develops into a pistil. In staminate flowers, petal and stamen primordia initiate spirally.

菖蒲属与香蒲目的茎叶解剖特征、叶表皮特征、花粉特征及花器官发生特点等亦存在着明显区别，特别是花器官发生特点差异尤为显著，如菖蒲属花器官发生过程中，没有苞片原基，也不存在任何形式的复合原基，花被与雄蕊原基均以单向性方式发生，雌蕊由3心皮发育而成，具有"盾状心皮"的特点等，黑三棱属则有苞片原基发生，且苞片原基与雌花原基起源于共同的复合结构，雄花的花被原基和雄蕊原基均以螺旋状方式发生，雌蕊由单心皮发育而成，未发现有2或3个心皮原基或其痕迹的现象，体现出"囊状心皮"的特点。

In this paper,we study the problem finding basic circle in plane graph,in which the number and coordinate of nodes and the node number of two ends of the side is given,we create a method,which is enlightened by the"proble of find way in labyrinth",to find way in branch point and then to find basic circle.

论文讨论了平面图形中存在着节点和边，在已知节点的坐标、标号以及边的标号和边两端的节点标号情况下，对其中存在的一阶环进行计算机搜索问题，提出了受"走迷宫"问题启发的一种在分叉点沿一定的方向进行搜索的方法。

These problems can be seen : the number of variables broken down by the huge market, many variables breakdown between strong relevance to the effective impact of the marketing work; In the face of new economic forms, and more detailed variables needed; By the development of methods and tools needed to be further strengthened.

可以看出其中存在的问题：细分市场中的细分变量数目巨大，许多细分变量之间存在较强的相关性，影响了营销工作的有效开展；面对新的经济形式，更多的细分变量需要提出；细分方法和工具的开发需要进一步加强。

If there is a thing called buttermilk, then butter also exists; and if there is a thing called butter, then buttermilk also exists.

如果有一种东西叫做酪乳，那么黄油也存在；如果有一种东西叫做黄油，那么酪乳也存在。

The system characteristic, exists in any system, also exists in the enterprise flow, but because the system characteristic is hides to the system internality, just like the enterprise the constitution, but the traditional enterprise flow management and the management method, usually all by the outward appearance angle of view and backwardness indicators, to evaluate the condition that enterprise target reach, achieves the goal by the flow operation achievement the means, often neglects the constitution flow intrinsic physique the characteristic, even not mention to in order to conforms to the industry to need and the environmental variation, the development enterprise manages some kind of system characteristic which should have.

系统的特性，存在於任何系统中，亦存在於企业流程中，但是由於系统特性是隐於系统的内在，犹如企业的体质，而传统的企业流程管理与经营方法，通常皆以外观的视角与落后指标，以评估企业目标达成的状况，以流程运作作为达成目标的手段，往往忽略构成流程内在体质的特性，更遑论为符合产业需要与环境变化，发展企业经营应该具备的某种系统特性。

The main difficulty in the state of art is that, the qualities of retrieval results by computers are much dependent on the features of images, and they have great differences with human beings who predict the degree of similarity of images through the image semantics.

主要问题是图像检索质量的好坏在很大程度上依赖于所使用的图像特征，它与人类根据图像语义来判断图像间是否相似的做法存在着很大的区别。这种差别的存在导致目前的大多数图像检索方法很难取得令人满意的图像检索效果。
