| 摘 要： | 本文分别用常规法和奇点析出法对井点进行处理，得到了用径向基函数配点法求解不稳定井流问题的2种算法．前一种算法在井点附近破坏了该配点法的无网格特性，而后一种算法是真正的无网格法．模型计算显示，后者计算精度远比前者高．

| Abstract: | Two methods based on radial basis functions and collocations are gotten to solve unsteady flow to well equations. One of the two methods is educated by treating the well with usual method and is not true mesh less method, while the another is educed by treating the well with polishing singular point and is true mesh less method and precise. |
