According to the statistic analysis of Prof. Amari on static recognition with neural networks, and introducing the concept of vector position stochastic variable of vector stochastic sequence, the stochastic variable is processed by DRNN. The relationship between input and output variance is analyzed. The stochastic analysis of dynamic identification is given, so as to explain the DRNN characteristics in recognition process.

第二，根据Amari教授对神经网络静态识别时的统计分析，引入矢量随机序列的矢量位置随机变量的概念，以该随机变量经过DRNN处理后，分析其输入与输出方差之间的关系，试给出了DRNN做动态识别时的统计分析，以从理论上说明DRNN在识别过程中的特性。

However, it can be noticed that there are obscurity and ambiguity in both theoretical explanation and practical employment.

但是，我们注意到，无论是在理论上的阐释还是在实践中的实施，目前还存在着一些模糊不清的现象。

Through the expounding of concepts and the analysis of literary texts of the epistemology of metaphors by Paul Demann, this article analyzes metaphor in literary texts, expounding the continuity, the dynamic feature, and the ambiguousness of metaphor in literary texts.

通过对保罗德曼隐喻认识论的概念阐释和对文本的剖析方法，从理论上对文本隐喻进行分析，阐述文学隐喻的延续性、动态特征和意义的不确定性。

However, during the practice of carrying the new rural cooperative medical service system, first we must solve these issues, such as: the ambiguousness of the attribute, the fuzziness of target location, the high cost and much difficulty of propaganda, the weak sense of peasants' heath care and shared risk, the weak administrative capacity of medical institutions, the worrying of doctor-patient moral standards, the lag of legislation, the low service level of designated medical institutions, the lack of operability in fund raises system and the weak responsibility consciousness of the government.

尽管我们在理论上能够阐明实施新型农村合作医疗制度的意义、试点的目标和要求、资金筹集和监管机制、医疗管理能力建设要求、完善农村卫生服务体系目标，但是在实施新型农村合作医疗制度的实践中，我们却必须要首先解决诸如属性不明确、目标定位模糊、宣传推动成本高、难度大、农民健康保健及风险共担意识淡薄、医疗机构行政管理能力较弱、对医患双方道德水准的担忧、立法工作滞后、定点医疗机构服务水平较低、筹资机制缺乏可操作性、政府责任意识不强等因素的制约。

It is very important to further study the corrosion behavior of bulk amorphous alloys in theory and application.

深入研究块状非晶合金的抗腐蚀性能无论在理论上还是实际中都具有十分重要的意义。

In this thesis we investigate the beam propagation and amphoteric refraction in a Uniaxially anisotropic crystal.

本文在理论上研究了单轴晶体中的光束传输和正负折射现象。

The 2×2 Jones matrix methods is used to analyze amplitude modulation characteristics.

采用2×2的琼斯矩阵计算仿真，从理论上分析了它的振幅调制特性。

The spiral curve structure can be used in slow-wave systems. Theoretically an analytic description for spiral curve slow-wave systems can be achieved after much simplification and approximation.

螺旋线结构就可以作为慢波系统；理论上，经过很多的简化和近似，可以得到关于螺旋线慢波系统性能的解析描述。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
