First,current research of kinematic properties of the Galaxy as well as their latest results are reviewed.Second,an updated,most complete catalogue of 209 open clusters with galactic longitude,galactic latitude,heliocentric distance,age,absolute proper motion and radial velocity data as well as 41 open cluster only with radial velociyty data is compiled.Also,the spatial distribution of the open cluster system is studied.

首先，本文综述了银河系运动学性质的研究现状，总结了历年来银河系运动学参数的研究结果；其次，本文在对最新疏散星团观测资料和文献进行调研和整理的基础上，编纂了迄今最完整的同时具备银经、银纬、日心距、年龄、绝对自行与视向速度的209个疏散星团样本以及只有视向速度资料的41个疏散星团样本。

Then, it studies the supply chain management system as a complex system to confirm the state existing during operating of the system. After that, it conducts a probability analysis on the state which the system located by applying supplement variable method, and establishes the model of distributed parameter system in a form of partial differential equations. Combining C0 ? semigroup theory in the functional analysis, it conducts a dynamic analysis on the established mathematical model. Using this method, it obtains the mathematical expression of the dynamic solution and the steady state solution, and proves the uniqueness, non-negativity and the asymptotic stability of the system solution. This dissertation applies the Matlab tool and uses two-step, three-step Simpson integral equation to imitate the condition of system solution. Then, it adds possible mode of failure and the optimization adjustment state to the system, based on which it has established the distributed parameter system model which is described by partial differential system of equations. Combining the functional analysis C0 ? semigroup theory, it studies the established mathematical model, and obtains the mathematical expression of the dynamic solution system and the steady state solution. It has proven the existing of uniqueness of the system solution, the asymptotic stability of system solution and the system solution. In addition, it has lying the theory rationale for further analysis and the research on the optimization of system.

本文首先简要综述了供应链理论、可靠性研究、鲁棒性研究以及供应链鲁棒性研究的现状；然后，将供应链系统作为一个复杂系统来分析，确定了系统运行过程中所经历的状态，通过引入补充变量的方法，建立了用偏微分方程组描述的分布参数系统模型，用泛函分析中的C_0 -半群理论得到了系统动态解和稳态解的数学表达式，证明了系统解存在的唯一性、非负性和指数阶渐近稳定性；并借助Matlab工具，利用二阶、三阶辛普森积分方程模拟系统解的性态，并给出系统动态解的仿真图；本文又对上述系统增加了系统可能失效状态和优化调整状态，并在此基础上建立了用偏微分方程组描述的分布参数系统模型，同样用泛函分析中的C_0 -半群理论对所建立的数学模型进行了研究，得到系统动态解和稳态解的数学表达式，证明了系统动态解存在的唯一性、非负性及渐近稳定性，为进一步分析和研究供应链优化奠定了理论基础。

To better understand this symbiotic relationship, scientists have turned to rapidly growing black holes -- so-called active galactic nucleus -- to study how they are affected by their galactic environments.

为了更好理解他们的共生关系，天文学家转向寻找演变速度相对较快的黑洞，就是所谓的活动星系核，以此来研究他们是如何受到星系环境的影响。

Ctive Galactic Nucleus is the hottest research on modern astrophysics. Blazars are one of the most extreme classes of active galactic nucleus, with high luminosity, large amplitude and rapid variability, high and variable polarization, radio core-dominance, and apparent superluminal speeds. Their broad band emission extends from radio up to γ-ray band, and dominated by non-thermal process.

GNs是近代天体物理学研究的热门课题，blazar天体是AGNs中具有极端物理性质的一个子类，它以大振幅快速光变、高且变化的偏振、射电核主导、视超光速运动、全波段非热辐射为主要特征。

The long parallel rays slanting across the top of the above radio image are known collectively as the Galactic Center Radio Arc and jut straight out from the Galactic plane.

斜穿过这幅射电图像上方的的长平行线合称为银河系中心的射电弧，这些弧刚好从银盘穿出。

The"not escaped"pulsars of each group whose simulated projective places on to the Galactic plane lie in the range 0＜r＜25 kpc and 5＜r＜11 kpc from the Galactic center respectively are selected to make statistics on absolute height |z| distribution to derive the segmental scale height and the cumulative scale height.

对每组中"未逃逸"脉冲星，分别在0＜r＜25kpc和5＜r＜11 kpc两个区域中对|z|分布做了统计，研究了"未逃逸"脉冲星在这两个区域中的分段标高和累积标高的演化特征。

Tom: You are right, he worked hard all the time.

你是对的。他一直都是努力工作。

Take shortcomings,failures,and mockings of others as commonplace and a drive to complete oneself,hold your own opinion over the evalution and disscution divested from others,afterwards sink into the state of eliminate mistakes if any or encourge oneself being not being influenced by the sayinngs of others or having no ideas to do.

把缺点、失败及别人的耻笑等看成是一种常事，当成完善自己的动力，对别人的评价和议论自己心中有主见，做到&有则改之，无则加勉&，不为人言所左右或无所适从。
