摘要
本文讨论了拉科斯特重力仪测量平差中的相关问题,指出其观测程序为相关观测,证明了相关系数理论值为0.5。所以应当采用相关平差才是合理的;另外自差(互差)超限返工重测后应取中数参与整体平差;独立平差点值中误差在理论上为相关平差点值中误差的2^(1/2)倍。
In this paper, the correlative problem of measurement adjustment of LCR gravimeter is discussed,and its correlative observation procedure is point out, and the theoretic correlative coefficient is shown to be 0.5.Therefore it is reasonable that the correlative adjustment should be used.Moreover,the mean must be applied to take part in the total adjustment when the self- (mutual-) difference is exceeded and the measurement has to be done over again.The mean square error of a point in independent adjustment is 2^(1/2) times that in correlative adjustment theoretically.
