陀螺仪 （gyroscope）

陀螺仪是用高速回转体的动量矩敏感壳体相对惯性空间绕正交于自转轴的一个或二个轴的角运动检测装置。利用其他原理制成的角运动检测装置起同样功能的也称陀螺仪。 Gyroscope is a kind of angular motion detection device which uses the moment of momentum sensitive shell of high-speed revolving body around one or two axes orthogonal to the rotation axis in relative inertial space. The angular motion detection device made of other principles has the same function, which is also called gyroscope.
