Anatomically, the nervous system is divided into the central nervous system and the peripheral nervous system

解剖学上把神经组织分为中枢神经系统和周围神经系统。

The results were compared among 4 groups. Results:①OCB positive rate was 37% in MS patients, which was lower than other reports, 24% in central nervous system infectious diseases group,5% in central nervous system non-infectious diseases group and 0 in peripheral nervous system diseases group,respectively.②OCB positive rate in conventional MS was 56%, which was higher than that in neuromyelitis optica.

结果①多发性硬化组OCB阳性率为37%，中枢神经系统感染组为24%，中枢神经系统非感染性疾病组为5%，外周神经系统疾病组为0；多发性硬化组的OCB阳性率比其他各组高，但低于国外报道的阳性率；②多发性硬化患者中传统型多发性硬化组OCB阳性率为56%，高于视神经脊髓炎组的11%。

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.
