摘    要：分析陀螺经纬仪灵敏部摆动的规律,发现舒勒公式及H·沃尔夫的数学模型带有局限性。因此,笔者根据一系列观测数据建立了一个新的数学模型,以便求得陀螺经纬仪动平衡位置可靠的N值,并使其中误差M_N减小。

Abstract: Gyro-theodolites, such as the Wild GAK-1 and Mom Gi-B1, have proved successful in azimuth determination by the point of reversion method in mine workings and tunnels. However, there are yet some questions left to obtain the most probable value N of dynamic equilibrium position in Gyro-theodolites. In the process of repeated analyses of the regularities of Gyro-Oscillation, the author noticed the limitations of the Shuler’s formula and the mathematic model by H. Wolf. And hence, a new mathematic model has been established by the author so as to obtain more reliable value N. In this thesis tee calculation of value N and the analysis of its reliability are based on a series of data obtained through observation. The results show that more rational mathematic model or formulae will obviously help to obtain reliable value N and reduce the mean square error M_N.
