摘　　要：为了使光纤陀螺仪能够工作在适宜的环境下,须预先对选定工作环境的温度与地表稳定性进行测量与评估。利用水平仪分别对选定的地下实验室和地面进行测量和分析,结果表明:地下室地表周日倾斜度变化小于0.5″,周日温度变化小于0.1℃,而地面地表周日倾斜度变化大于2″,周日温度变化远远大于0.1℃。地下室的环境条件更接近光纤陀螺仪的环境需求,地下实验室相对于地面环境更稳定,可以为光纤陀螺仪提供一个稳定的实验环境。For ensuring the fiber optic gyroscope（FOG） a suitable environment, the temperature and stability for the selected working environment have to be measured and assessed in advance. The measurement for the ground and the selected underground laboratory environment were conducted by using a tiltmeter, and the analysis results show that the diurnal tilt change and the diurnal temperature change are less than 0.5＂ and less than 0.1℃ respectively for the underground laboratory, whereas the diurnal tilt change and the diurnal temperature change are more than 2＂ and much more than 0.1 ℃ respectively for the ground. The environment condition of the underground laboratory is more close to the requirement of the FOG; and is much stabler compared with the ground. The underground laboratory can provide a stable experimental environment for the FOG.
