下界

A switching strategy and an algorithm which guarantee that the system is uniformly ultimately bounded are given.

给出了切换策略，以及使切换系统在此切换策略下是终极一致有界的算法。

Theoretically,the system is globally uniformly ultimate bounded.

从理论上论证受控系统在设计的控制器作用下是全局一致毕竟有界。

A stability proof is given strictly in the sense of Lyapunov. It is shown that all the signals in the closed loop systems are uniformly ultimately bounded.

在很弱的假设条件下，应用李雅普诺夫稳定性理论证明了闭环系统内的所有信号为一致最终有界。

The multivariable systems with unmodelled dynamics can still obtain better control results under the action of stronger bounded unmeasurable disturbances.

对于存在未建模动态的多变量系统，在较强的有界不可测干扰的作用下仍可得到较好的控制结果。

Covers architecture, interior, industrial, plane, brand and interaction Design field, in all AUTODESK "puluodi" and innovative enterprise world-class, driven by the influence of the recognition, promotion and advanced Design concept, non-commercial, cross-border etc, this award was unique position immediately after Design industry, Manuelsaez bodacious, Nike, SOM, IDEO project Icon, Aircraft, fuse, Smart, too, RKS Whipsaw Continuum, and Pentagram DAREZ, world top brand and Design of such organizations to participate in global Design industry, quickly became a symbol of the most exciting adored.

涵盖建筑、室内、工业、平面、品牌、交互等所有设计领域，在"惠普"和"AUTODESK"等世界级创新企业的影响推动下，加之其以表彰、推广超前设计概念、非商业性、跨界等独有定位，该奖项诞生后立刻风靡全球设计业界，Manuelsaez、Nike、SOM、IDEO、fuse project、Icon Aircraft、Smart Design、RKS、Pentagram、Whipsaw、Continuum、DAREZ等世界顶级品牌和设计机构纷纷踊跃参与，迅速成为全球设计业界最为令人追捧的一个标志性奖项。

Be born in Hong Kong, outside Yu Hai of attend school of one's early years, job big company, smile is like sunshine forever kind bright, there is no lack of on Gu Yongqiang body " horse " advantageous temperament, but hit in domestic Internet group for years go all out, poineering experience, below the appearance that makes him gentle, more under cover of a kind of dash, reason, consolidate step by step " aardwolf " spirit.

在香港出生，早年求学、工作于海外大公司，笑容永远如阳光般灿烂，古永锵身上不乏&马&的优越气质，但多年在国内互联网界打拼、创业的经历，使得他温和的外表下，更隐藏着一种锐气、理性、步步为营的&土狼&精神。

Recently, a nearly E-W-striking, over 10 km long albitite zone has been recognized for the first time in the Lower Silurian Meiziya Formation in a Lower Paleozoic lead-zinc ore deposit concentration area of the Xunyang basin, South Qinling. It shows a conformable contact and gradational relationships with the country rocks and has thick-bedded and massive, banded, brecciated structures and fine and very fine equigranular and intraclastic textures. It is chemically characterized by enrichment in SiO2, Al2O3 and Na2O and is rich in the trace elements Fe and Mn and poor in the trace elements Co, Ni and Cu. Its ∑REE, LREE and HREE are lower than those of the country rocks and exhibit pronounced Eu depletion.

最近，在南秦岭旬阳盆地下古生界铅锌矿集区内的志留系梅子垭组地层中首次识别出一条近东西方向延伸长达10余千米的钠长石沉积岩带，与地层整合产出，渐变过渡，厚层块状，条带状，角砾状构造，均粒微-细晶结构，内碎屑结构；其化学成分以富含SiO2，Al2O3及Na2O为特征，富Fe，Mn，贫Co，Ni，Cu等微量元素；该钠长石岩的∑REE，LREE，HREE均较围岩偏低，具明显Eu亏损的特征。

The analysis of dynamic performance of the overall system is performed by using Lyapunov method, which proved that by using the proposed method uniform ultimate boundness of close-loop error is guaranteed under certain conditions.

使用Lyapunov方法对整个系统的动态性能进行分析，证明了在一定条件下此方法能保证闭环误差及网络权值一致最终有界。
