摘　　要： 概述了无网格再生核质点法的近似方案和本质边界条件的处理;综述了再生核质点法在结构动力学、大变形分析、计算流体力学、断裂及损伤力学、微机电结构分析中的应用;从工程应用和改进再生核质点法的角度提出了未来的若干研究方向. The reproducing kernel particle method (RKPM) , which utilizes the notions of the convolution theorem, multiresolution analysis and meshless properties, is reviewed. Emphasis is put on the reproducing kernel approximations and implementation of essential boundary conditions for RKPM. An overview of the current application areas of RKPM is given including structural dynamics, large deformation, hyperelasticity, computational fluid mechanics (CFD), damage problems and microelectromechanical systems analysis. Some future research areas, from the point of view of engineering application and futher development of RKPM, are pointed out. These promising research areas may include mould filling simulation, meshless modal analysis, treatment of essential boundary conditions, coupling to finite element method, enhancement of the emcency of RKPM and development of meshless environment.
