| 摘 要： | 在半球谐振陀螺工作的过程中，环境温度的变化是不可避免的。温度的变化影响谐振子尺寸变化，导致陀螺产生热漂移。根据振幅检测原理，推导温度效应误差的数学表达式，分析它对测量结果的影响，这对选择合适的补偿算法以消除温度效应误差有一定的指导意义。

| Abstract: | In the working process of the HRG（Hemisphemical resonator gyro）, the temperature change is inevitable. The temperature change leads to the shift of HRG structure size so that the output of HRG produces thermal drifts. On the basis of amplitude detecting theory, the temperature effect error equation is deduced and its effect on the measuring result is analyzed. The analysis can provide a guidance in choosing proper compensation ways to remove the temperature effect error. |
