【Abstract】 In order to improve the finite analytic method’s adaptability for irregular unit, by using coordinates rotation technique this paper establishes a five-point element scheme of finite analytic method. It not only solves unsteady groundwater flow equation but also gives the boundary condition. This method can be used to calculate the three typical questions of groundwater. By compared with predecessor’s computed result, the result of this method is more satisfactory.更多还原
