强震加速度波形积分时的基线修正

Correction of Datum Line when Integrating Strong-vibration Acceleration Wave-form

介绍振动参量转换的意义和加速度积分为速度和位移时基线修正的必要性和两种具体方法:最小均方速度法和零终值条件法。

The significance of transforming the vibration-Parameter, the necessity on the correction of datum line when Integrating acceleration into velocity and displacement have been described.Two specific methods (Least square velocity method and zero end value condition method) have also been presented
