Software Implementation on Automatic Curve-fitting during Pumping of Unsteady Flow

Some problems have existed in solving hydrogeological parameters in unsteady flow pumping tests using traditional curve-fitting method,such as numerous calculational steps,repeated characteristics,and random results,the judging method of both curvature and distance was introduced based on curve fitting method,and with computer programming,computerization of manual curve fitting,and the completely automatic curve-fitting function were realized,the curve-fitting efficiency of practical engineering was considerably increased.
