摘　　要：本文根据气象法三角高程测量的特点,提出了同时解算高程改正、垂直温差改正和垂线偏差的新三角高程测量间接平差法。采用这种平差方法不但能使现代三角高程测量平差的方法更加严紧,从而提高三角高程测量的精度,而且使得在三角高程测量中内插垂线偏差成为可能。According to the characteristics of trigonometrical levelling, a new adjustment method of intermediate observation, which could simultaneously determine the alti- tude correction, the vertical temperature difference correction and the vertical derivation, is presented in this paper. Adopting this method could not only enable the adjustment method of trigonometrical levelling to be more accurate, but also determine the vertical derivation together with the trigonometrical levelling.
