It will expose the design problem of maintainability of civil airplane to the early stage of design. This paper discusses the composing of the virtual maintenance environment, builds non-immersion virtual maintenance environment of undercarriage, and establishes a part library management system. The characteristic of maintainability models and maintainability analysis based on virtual technique is researched to give the maintainability frame model of civil airplane virtual maintainability analysis. All levels of maintenance time model and maintenance man-hour model are established. Analog-Huffman code is proposed to optimize space partition method in traditional collision detection arithmetic."Maintenance therblig"is brought into the broken down of maintenance tasks, and the new maintenance tasks broken down method is proposed. The demands of human measure, position, and equipment layout in human engineering are discussed, and the verification methods of human measure, position and equipment layout in virtual maintenance are given. Basic principle and verification procedure of maintainability virtual verification is developed primarily, and the reachablity, the visibility, and posture-comfortability are verified.

Using characteristic description to define High-Tech fields is mainly expressed by the summary of design thought, material application,structure treatment and construction properteis. In the 1950s, Early High-Tech school focused mostly on technology application and standardization ; in the 1970s, they emphasized industrial techinic, mainly using industrialized steal profil, glass, plastic, metal sheet and tightwire of mass production to display industry succes. In 1990s, late High-Tech school proposes durable developpement concept, to pay attention to tract, to bring importat emation factor into conception, to improve energy using rate, to protect ecological environment, and to creat comfortable environment.

借助一些特征的描述来界定高技术的范畴，主要表现为设计的思想精神、对材料的运用、结构的处理及施工特点等方面的归纳和总结。20世纪50年代早期高技派集中在高技术的采用与构件的装配化、标准化；20世纪70年代强调表现工业技术，主要使用工业化批量生产的型钢、玻璃、塑料、金属板和钢索这些材料炫耀工业成就。20世纪90年代后新高技派，倡导可持续发展理念，注重场所地域性，更发挥情感在设计中的重要因素，用高技术来提高能源使用率，有效地保护生态环境，营造舒适宜人的环境。
