摘　　要：分析了激光陀螺刻度因子随温度变化的特点,指出了激光陀螺刻度因子与环境温度、温度增量和温度变化率有关,提出了激光陀螺刻度因子温度误差的三因素三层BP网络新模型,模型结构简单。实测数据的仿真结果表明,模型精度高,均方差优于6.1×10-7("/pulse)。The changing characteristics of the laser gyro＇s scale coefficient as the temperature changes is analyzed in this paper. That the laser gyro＇s scale coefficient is relevant to environment temperature, temperature increment and temperature derivative is presented. A novel BP network model of laser gyro＇s scale coefficient is proposed which has 3 factors and 3 layers. The model is simple, Simulation testing of experimental data verifies that the model＇s precision is improved greatly, mean squared deviation is smaller than 6.1 ×10^-7（＂/pulse）.
