Abstract: Make One（MO） is a new architecture of universal electronic equipment which is based on software function components.The description model of MO components is not only the foundation of building MO components library but also the basis of the MO components classification and retrieval.According to the characteristic of MO architecture，an integrated description model MOCDM（Make One Components Description Model） of MO components is proposed.Based on XML，the MO components description language xMOCDL（XML Based Make One Components Description Language） is also defined.At last，an example is given to illustrate the idea of the paper.

Key words: Make One mode, component, description model, XML

摘要： Make One模式是以应用功能构件为核心的一种新型电子信息设备模式。对Make One应用功能构件的有效描述是构建Make One构件库的基础，是对Make One构件分类、检索的依据。根据Make One模式的特点，提出一种集成式的Make One应用功能构件的描述模型MOCDM（Make One Components Description Model）；并基于XML，定义了Make One应用功能构件的描述语言xMOCDL（XML Based Make One Components Description Language）。最后，给出一个描述实例予以论证。
