The main contributions and innovations are as following:1 A new task decomposition model is proposed, which can decompose any maintenance task into task units, action units and motion elements. Based on virtual human`s kinematics model, an action classification criterion is provided, which is especially suited for maintenance simulation. Based on parametric modeling and encapsulation of maintenance actions, a Virtual Human's Action Database with a hierarchical architecture is designed and developed. Aiming at the reusability difficulty of captured motion data, a motion retargeting method based on path transformation is developed to reuse captured data, and several kinds of periodical ground locomotion actions are realized.2 In motion data compression, a key frame extraction algorithm based on kernel clustering method is proposed. Using Mercer kernel functions, motion data is mapped from the original space to the high-dimensional feature space, where the clustering process can be realized more efficiently. 3 A Petri Net-based locomotion-planning model is proposed to realize virtual human`s locomotion planning and walking control in dynamic environment.

After selective extraction, the cyst wall of two kind of resting cysts displayed a filament network. In the resting cysts of Tachysoma pellionella and Euplotes encysticus, the filament was located in mesocyst and endocyst respectively. On the other hand, a special filament scaffold region was observed below the cyst wall in two kind of cysts. Compared with the true IF which was located in central part of cyst, the filament of this region was net as well as uniform, and no any cytoplasm residue can be seen in this region. In the resting cyst of Euplotes encysticus, a filamental boundry which partitioned the special filament scaffold region and the true IF region was observed.
