R·Quirk and other experts divide passive voice into three types : true passive , quasi-passive and pseudo-passive .

一导言英语中的语态是一个语法范畴，是表示主语和动词之间关系的动词形式。

Zhang Keli and some other grammarians divide the passive voice into three kinds: true-passive, pseudo-passive and quasi-passive.

张克礼等一些语法学家认为被动语态可以分为三种：真被动，假被动和半被动。

On the other hand, from the point of view of work manner, thedetecting systems can be classified two kinds: the active and the passive systems. Althoughthe passive detecting system can\'t get so much information as the active one, it has itsspecial characteristic. For instance, the passive system is immune to the radar clutter. It issecreting and has no electromagnetic pollution due to none of radialization. The passivesystem also has excellent capability of detecting the target covered with the stealth material.

从工作方式来看，探测系统还可分为主动和被动两种方式，虽然主动工作方式可以获得关于目标的更多信息，但是被动工作方式也有其不可替代的特性，如不受闪烁效应的影响；由于本身不发射电磁波，因而没有电磁污染及工作比较隐密；对覆盖吸波材料的目标探测能力很强等。

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。

There are two types of passive voice used in English: passive structure and quasi passive structure.

英语中的被动式有两种类型，即被动式和类被动式。

The English passive voice can be divided into the actional passive and the stative passive.

摘要英语被动语态可以分为行为被动语态和状态被动语态。

Some prepositions, not only can collocate with the actional passive, but also with the stative passive. Some prepositions can only collocate with the stative passive.

有的介词既可以与行为被动语态搭配使用，也可以与状态被动语态搭配使用；有的介词却只能与状态被动语态搭配使用。

As for the translation of passive voice in EST, the passive structure can remain unchanged. Passive sentences in English are translated into active voice in Chinese by changing original objects or subjects, adding subjects, and being converted into subjectless sentences or other structures for a good translation.

对于科技英语中被动语态的翻译，被动结构可以在汉语中保持不变，但大部分被动句的翻译是通过转换原句主语和宾语或者是增添主语，转化为汉语的主动语态，也可以是转化无主句和其它结构，从而使译文更通畅。
