The dynamic model of this hydraulic servo joint is established by the hydraulic simulation theory and the lagrangian equation respectively . furthermore , the dynamics property of this joint system is comprehended through the simulating , comparing and analyzing . all the results show the dynamic stabilization of this joint system 采用液压系统仿真的手段以及拉格朗日方程建模的方法建立了液压伺服关节系统的动力学模型；通过计算机仿真及其仿真结果的对比分析，进一步了解了液压伺服关节系统的动力学性能，验证了液压伺服关节系统的动态稳定性，为控制系统设计打下了基础。
Competition between individual enterprise and individual enterprise no longer exists , having been replaced by confrontation between the overall strength of supply chain and supply chain . supply chain alliance broke the existing structure of the value chain , reengineered and optimized products , customers , technology and other resources . therefore , this new cooperation model of enterprise , supply chain alliance ( sca ) , becomes one of the most important management strategies leading enterprise to success , and is considered as the evolutional mainstream of the future enterprise organizational form 本文引入诞生于生物科学领域的共生理论,吸收和发展国内外供应链联盟相关领域的最新研究成果,从对供应链联盟的基本认识和发展方向入手,分析了供应链联盟中的共生现象以及形成共生的条件,提出了供应链联盟共生系统的概念,建立了供应链联盟共生系统模型,用数学模型表达了联盟共生系统的生存环境、能量空间模型以及联盟共生系统发展能量模型,重点阐述了供应链联盟共生动态稳定性以及联盟共生能量分配。
In this treatise , 1 do the research for such problem . firstly , i build the dynamic numeric model of the wind turbine , then make the simulink block with matlab software which combined with the corresponding algorithm to dynamically simulate the power system including wind power , and make the program with fortran and visual foxpro to analyze such system 在本论文中，就这个问题予以了研究，首先建立了风力发电机的动态数学模型，然后，结合了相应的算法利用matlab软件编制了仿真模块，进行了动态仿真，同时利用fortran与visualfoxpro语言编制了相应的程序实现动态稳定性分析。
Abstract : the slope dynamic stability with elasto - dynamics vibration and wave theory and boundary element method ( bem ) is analyzed and calculated . it raises a criterion for slope dynamic stability . it gives an exmple for calculating the stability of soil slope under the action of earthquake waves emitted from underground and draws the dangerous range in which the slip line lies 文摘:主要分析边坡动态稳定性问题，采用地震波作动载荷，用边界元法对边坡进行分析，并在计算机上实现.对动态稳定性判据从理论上进行了探讨，给出了动力危险线的位置
