英文摘要：

This paper reports the principle structure and properties of the sensitive level posture and acceleration sensor. By using the ＂pendulum＂ characteristics in the natural gas convection, as well as the principle of combination of inertial sensors, signal processing and performance, which eliminated moving base acceleration signal interference on the level of posture gas tilting by gyroscope, this paper discusses the natural convection of floating gas lift and pendulum characteristics, contrasts the gas pendulum parameters with the solid one, and analogizes the laminar jet angular rate gyroscope and the traditional gyroscope working principle. The article demonstrates the working principle of the combination of gas pendulum inertial sensors and signal processing technology. The experimental results verifies the sensor has the capability of resistiing acceleration interference.
