【Abstract】 In this paper, adjustment model selection for data processing of EDM trigonometric levelling is discussed. Then different models are used for the processing of data from the Xin’anjiang power plant. Through comparison and analysis, the practical model is studied for reduction of refraction error in data processing.更多还原
