| 摘 要： | 本文提出了一种温度对陀螺经纬仪稳定性影响的测试方法,引入了单因素方差分析的数理统计方法,评价陀螺经纬仪在高低温环境下的稳定性;对高低温稳定性测试过程中观测窗变形的影响进行了分析和实验研究,认为本文中采用的高低温室观测窗的变形量,对中低精度的陀螺经纬仪高低温稳定性测试而言可以忽略;最后通过实际测试数据验证了该方法的可行性。

| Abstract: | Test method for the temperature effect on the gyrotheodolite stability was put forward in the paper.It imported single-factor analysis of variance to estimate the gyrotheodolite stability under high-and-low temperature environment.The impact of the observation window distortion was explored in the high-and-low temperature stability test through analysis and experimentation.It was considered that the magnitude of the observation window distortion,which this paper was introduced,could be neglected in the test of middling or low precision gyrotheodolite stability for high-and-low temperature.The method was validated feasible through practicality test data finally. |
