In this context, information literacy has been an important indicator for assessing a talent＇s comprehensive quality. As a compulsory public course for college students not majoring in computers, computer basic course plays a significant role in cultivating college students＇ information literacy. However, how to improve contemporary college students＇ information literacy, facilitate the teaching reform in fundamental computer education, and effectively improve college students＇ capacities of solving problems with computers is a difficult question faced by fundamental computer education in colleges and universities展开更多

For a regenerated mechanism, at first, the method identifies its type and structure andchanges it into a rigid structure by fixing the ground link and the input link. And then this rigidstructure is decomposed into a set of basic kinematic chains (BKCs). By matching the type of BKC,the displacement analysis equations can be set up, and all possible configurations, in whichpositions of all movable links are considered, can be given out.展开更多
