Only an arbitrary single pulse among pulse train with temporal separation of about 1 ps was trapped by soliton pulse,the trapped pulse was blue-shifted and the optical spectra of trapped pulse was distinctly separated from those of the untrapped signal pulses.The trapped pulse can be easily picked off using a wavelength filter such as a fiber Bragg grating.

通过数值求解光子晶体光纤中脉冲传播满足的耦合非线性薛定谔方程，发现用孤子脉冲可俘获信号脉冲串中的任何一个脉冲，被俘获的信号脉冲的中心波长明显蓝移，在频域上和其他信号脉冲分离开来，于是让信号脉冲串在输出端通过布喇格光纤光栅，被俘获的信号脉冲将被过滤掉。

The essential problem of KBOOA are acquirement and organization of knowledge about the application domain. First of all, we recognize objects according to their outside characteristics and build stable concepts structures. In this way, the attributes and behaviors of any objects are treated as objects as well. The concepts are organized in hierarchies, the concepts' semantics are demostrated in the form of conceptual graphs. As hierarchy structure has inheritance, the system has ability to recognize and reuse concepts, analyze and reason the acquired information according to the existing knowledge, understand the problem space and present the system's functions and characteristics to the analysts and users in the form of scenarios. The main means of transforming informal requirements to formal ones is to recognize objects according to their outside characteristics, recognize attributes according to their functional dependence and describe the semantics of objects, behavior and attribute's relationship's because there is a automatic map from the descriptions of attributes and behaviors to class structures. It is difficult to transfer from OOA to OOD, We disscussed the modularity of Object-Oriented programs according to the principles of software engineering and presented the methods to decrease couplings and increase cohesions, i.

KBOOA以知识的获取、组织为中心问题，首先依据对象的外特性识别对象，并将属性和行为也作为对象处理，从而建立起较稳定的概念结构；KBOOA以层次的方法组织概念，以概念图的形式描述概念的语义，利用层次结构的继承特性，使系统具有识别、重用概念的能力，根据已有知识对系统所获信息进行分析、推理，产生对问题空间的理解，并以想定的形式向分析师、用户展示系统功能、性能，从而构成了一个交互式的，具有一定智能的需求分析环境；依据外特性识别对象，依据函数依赖关系识别属性，用概念图描述对象、行为及属性关联，是将需求由非形式化形式向形式化形式转换的主要手段，使属性及行为描述可向类型结构自动映射，为提高需求分析的自动化程度提供了依据。
