摘　　要：通过对矿井常用的TJ-9000陀螺经纬仪进行温度实验测试,结合单因素方差分析,认为温度变化对于该陀螺寻北影响明显,并建立仪器陀螺主轴位置随温度变化相对变化方程。建立基于井上下温差变化仪器常数补偿方程,从必要性和精度可行性论证因温度变化而进行仪器常数补偿的优越性。Through a series of tests on the TJ-9000 gyro theodolite for the influence of temperature variation, considering the variance analysis from mathematical statistics, there have been ample reasons to believe that the instrument constant shows an obvious linkage with the temperature variation. Based on this, the regular and tendency of the axis position--variation for the temperature variation are disclosed. Based on the conclusions, established a compensation equation of the instrumental constant for the temperature variation and give the exhibition of the advantages no matter referring to the necessity or from the feasibility for precision.
