本文介绍了气流式加速度传感器研制的理论基础及其基本实现方法。探讨了利用热线测量密闭腔体内温度的变化来计算外力(加速度)对敏感体作用的原理。 This paper introduces the theoretical basis of air-flow acceleration sensor and its basic realization method. The principle of calculating the effect of external force (acceleration) on the sensitive body by using the hotline to measure the change of the temperature in the closed chamber was discussed.
