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.

结果说明，（1）一年生山野豌豆由于其生育期短，在整个生长季节内生长缓慢，所以其基本没有利用价值；二年生山野豌豆和三年生山野豌豆因其生育期长、生长速度快、生物产量高等特点，有较高的利用价值，其中，三年生山野豌豆的利用价值高于二年生山野豌豆。

The Markov forecast model, time series method (triple exponential smoothing method and a combined of triple exponential smoothing method and Markov model) and stepwise regression forecast method were choosed, and the basic principles and processes of the three models were analyzed and compared. Based on above, the three methods were used to predict population dynamic of Cricetulus barabansis and Meriones unguiculatus. The characteristic, accuracy and applicability of three methods were analysed and compared. The results showed that,(1) Markov model belongs to a middle-long time forecast model, and the result was interval forecast, but it reached the requirement of forecasting the harmful population dynamic of rodents. Through the forecasted population dynamic of Cricetulus barabansis and Meriones unguiculatus in 2004, the results were accurate; this meant that Markov model was a good forecast model to Cricetulus barabansis and Meriones unguiculatus population.

选择马尔可夫链预测模型、时间序列分析法(三次指数平滑法、三次指数平滑法和马尔可夫链预测模型的组合预测法)和逐步回归预测法，对这三种模型的基本原理、模型的构建过程进行对比分析，在此基础上用此三种方法预测了黑线仓鼠和长爪沙鼠的种群数量，并对三种方法的特点、预测的准确度和适用范围进行了比较分析，结果表明：(1)马尔可夫链预测模型属于中长期预测，预测的结果为区间预测，但对于害鼠种群数量的预测来说已经达到要求，通过对2004年黑线仓鼠和长爪沙鼠种群数量的预测，预测的结果都比较准确，这说明对于预测黑线仓鼠和长爪沙鼠种群的数量动态，马尔可夫链模型是比较好的模型。
