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.

the fast transposition algorithm to sparse matrix expressed by triple list is introduced.this algorithm needs to determine the position in the transposed matrix position of the first element which is not equal to zero in the original matrix each row,it uses two arrays as auxiliary space.in order to reduce the auxiliary space which the algorithm needed,an improvement is made through introducing two simple variables.the improved algorithm saves a half auxiliary space compared to the original algorithm at the same time complexity.

摘 要：介绍基于三元组表表示的稀疏矩阵的快速转置算法，此算法在转置前需要先确定原矩阵中各列第一个非零元在转置矩阵中的位置，在此使用2个数组作为辅助空间，为了减少算法所需的辅助空间，通过引入2个简单变量提出一种改进算法。该改进算法在时间复杂度保持不变的情况下，空间复杂度比原算法节省一半。
