经过大量的试验和计算分析表明，环境温度变化率和环境温度梯度对光纤陀螺零位漂移的影响大于环境温度对漂移的影响。
By large amount of experiments and calculations, the result shows the effects on FOG accuracy of temperature rate and its grads are greater than of only the temperature itself.
本论文从理论和实验上对周围介质折射率敏感的触点式熔接型光纤液位传感器的传感头进行了研究。
The sensor head of fusion fiber-optic single-point liquid-level sensor is investigated experimentally and theoretically in this paper, which is sensitive to the refractive index of surrounding media.
在建立光纤陀螺漂移与温度的混合线性回归模型时，考虑温度变化率和温度梯度等因素的影响，对光纤陀螺零位漂移的温度补偿精度更高。
So the compensation accuracy of FOG drift can be improved by introducing the temperature rate and its grads when establishing the mix linear regression model.
