摘　　要：采用有限元方法,计算了不同温度下倾斜10°时敏感元件内的温度场和流场,分析和验证了环境温度对气流式水平姿态传感器灵敏度的影响机理。结果表明:随着环境温度的增加,传感器灵敏度降低;反之,随着环境温度的下降,传感器灵敏度提高;倾斜10°时,传感器的灵敏度温度系数为0.55mV/℃。The temperature and stream fields in sensing element with tilt angle of 10° at different temperatures were calculated by the method of finite element, and the effect mechanism of environmental temperature on the sensitivity of the airflow level posture sensor was analyzed and validated. The results are as follows： the sensitivity of sensor decreases with increase of environmental temperature; conversely, it increases with the decrease of environmental temperature; when the tilt angle is 10°, the temperature coefficient of sensor＇s sensitivity is 0.55 mV/℃.
