摘　　要：给出了重复线质量评价指标,并提出3种方法来提高重复线的内符合精度。利用3个测区的实验数据进行比较分析,结果表明,新方法处理重复线在一定程度上提高了内符合精度,并就航空重力测量重复线处理提出合理化建议。Qualified repeat lines of airborne gravity is the prerequisite of measurement. With poor quality repeat lines eliminated and intercepted,all the repeat lines could meet the internal accord accuracy requirement in airborne gravity.This article provides quality evaluation indexes of the repeat lines and three new methods to improve the internal accord accuracy.The study result shows the new methods could improve the accuracy.In the end,some reasonable proposals are put forward to deal with airborne gravimetry repeat lines.
