Firstly this paper probes for the conception and the basic theory about brand assets by pointing out that brand is a kind of assets and is subordinate to category of assets, so brand assets assessment certainly applies for general theory in assessing assets and is restricted by basic assessment theory, the correct assessment of brand asset will inevitably be also helpful for development and the completeness of the entire assessment profession;Meanwhile, brand assets is a special intangible assets after all, therefore its assessment differs from that of common assets.

文章首先探讨了品牌资产的相关概念及基本理论，指出品牌是一种资产，隶属于资产的范畴，品牌资产评估也必然适用于一般的资产评估理论，受基本评估理论的制约，而品牌资产的正确评估也必然有利于整个资产评估行业的健全与发展；同时，品牌资产毕竟是一种特殊的无形资产，它不同于商标，也不同于商誉，有着自己独到的特点，所以其评估与一般的资产评估又有所区别，要正确评估它的价值必须正确辨析这一组概念。

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.

The theory of accretion disks are important for many astrophysical phenomena, including Quasars, active galatic nucleic, X-ray binary stars, and young stellar objects. The most important branch of accretion djsk theory is the stability properties of djsks. It is widely considered that the luminosity variations of various astronomical objects are associated with the instability of accretion disk. The viscosity plays an important role in the accretion disk theory, and magnetic field exists commonly in astronomical phenomena. A more realistic analysis of the stabihty of the accretion disk should include both the radjal and azimuthal perturbations because of the strong shear of viscous flow.In this paper, according to the luminosity Variations of Various astronomical objects, we study the radial-azimuthal instability of an isothermal with magnetic field. We find that the radial and azimuthal fields B〓,B〓 are mainly responsible for enhancing the instability of the magneto-acoustic modes and non-axisymmetric modes,and that pulsational oscillations are larger in the radial than in the Z direction. The model may be useful in explaining the periodic light variation of FU orionis and. T Tauri stars.
