摘　　要：分析了无单元法研究的现状及存在的主要困难 ,从影响半径、基函数、权函数等几个方面提出了对进一步发展无单元法的一些设想 .着重讨论了使用动态影响半径的无单元法 。After analysing the situation of studies on Element-Free Galerkin method (EFG) and some difficulties arising in the process, some ideas aiming at influent radius, basis function and weight function are put forward to further develop EFG, with one of these ideas, EFG with dynamic influent radius, as the focus of the discussion. Moreover, two numeric instances justify the reasonability and feasibility of using dynamic influent radius.
