In order to study the mechanism from the structure of face-contacted blocks,based on the theorem of the movability of the face-contacted blocks, the method of vector analysis to distinguish the blocks’ movability is supplied in this paper.

In order to study the structure of face contacted blocks,the movability of three kinds of the face contacted block has been studied by vector analysis ,the scope of key blocks is dwindled, and the base for further study of the structure face contacted blocks has been established.

The priblem of linkage movability exists in linkage synthesis after choosing the linkage type.

The conclusion about unconditional mobility was got according to the active/passive prismatic joint.

This paper presented a general method, which is used in solving the mobility condition of planar multiloop and multiDOF mechanisms by the mobility conditions and the workspaces of planar singleloop linkages.

Taking the mobility analysis of a kind of 2-DOF multi-looped hybrid driving mechanism as an example,an analytic method of mobility which suits similarly to other multi-DOF and multi-looped hybrid driving mechanisms was presented.

This paper expounds the factors influencing the developing direction of the information network and the digital library,and probes into the requirements of the users in three aspects of the individualization,network self-service,and the mobility and its technologies.

Some of them enjoy the attribute of syntactic mobility according to which idioms can be categorized into fixed and mobile idioms.
