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。

Pulp mold packaging product is a kind of elaborate paper product, which is made of pulp of waste paper or plant fibred. Using metal mold with lots of very small mesh and bringing proper pumping pressure to make the pulp cling to the metal mold, the pulp mold product is shaped after being dewatered, taken out of mold, drying and formed with hot pressure.

纸浆模塑包装制品是采用一定浓度的纸浆或植物纤维浆，通过具有大量网孔的金属模具，利用一定形式的吸附压力使纸质或植物纤维均匀地沉积在模具外表面上，经脱水、脱模、烘干及热压整形而制成的较精细的纸模产品。

But we don't care about Battlegrounds.

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
