Bearing in mind that elaboration theory contributes much to the establishement and following pick-up of the words,this paper cites some examples to indicates the thoery is beneficial to build-up of the learners’ vocabulary,improving the dimension and breadth of learners’lexical knowledge.

While in the studies of the acquisition and retrieval of knowledge,researchers found that elaboration theory efficiently facilitates the acquiring and retrieving information,and therefore,it has been widely used in the domain of language teaching research and practice.

This paper attempts to try out a new approach to the sentence-based C-E translation exercise Elaboration Theory and teaching practices at class.

Based on the theory of elaboration, this project makes a survey of, by means of experiment, the different effects of English vocabulary teaching and learning by adopting different ways of presentation.

Declarative knowledge is stored in propositional network, and elaboration, as a knowledge organizing structure, is the source of misguided inference.

Based on the theories of elaboration and mental lexicon, the present study has investigated and tested, by use of experiments, the different effects of English vocabulary teaching and learning by adopting 3 different presentation modes.

The increment theory and the increment numerical method are used to analyzed the elastic-plastic dynamic buckling of ring-stiffened cylindrical shells under c ombined loading (axial fluid-solid impact loading and radial uniform external pressure).

And the increment theory and Lagrange multiplier algorithm about the non-linear problem are illustrated.

A 2-dimensional elasto-plastic finite element model of metal orthogonal cutting was developed based on large deformation-large strain theory,incremental theory and updating Lagrang- ian formulation.

By taking double fifth B-spline functions as the displacements trial functions and using the elastoplastic incremental theory, the basic iteration formulas of the problems are derived.

In this paper,the schemes of the finite analytic method(FAM) in local coordinates for solving the elastic plastic boundary value problem of incremental theory are derived, which can be utilized to solve the problem in a domain of comparatively complicated geometry.
