摘要
提出了一种新的动态校零方案，它具有校零精度高，不受元件参数变化影响，不压缩频带下限，不带来附加噪声等特点。采用该技术后，可使压电陀螺的零位稳定性和零位重复性提高１～２个数量级。在舰载导弹制导系统。
With the object of rectangular composite plate, the equal elastic constant of composite plate is determined from the theory of elastic plate, and the flexual vibration equations of the composite plate are derived. Moreover, a simple analytic expression of resonance frequency of the vibrators is found using the apparent elastic method. Since the calculation is simple, this method may be a reference for the research and engineering technicians.
