| 摘 要： | 本文阐述了地面转动对回转式拾振器反应的影响，指出目前使用的加速度计基本上均为回转式小折合摆长的加速度计，地面转动对摆反应的影响很小，可略去不计。由于在摆的输出中，转动分量所占的分量很小，故不能在丁程强震中采用现有加速度计来提取转动信息。本文给出了转动拾振器的2个方案：陀螺方案及双摆方案。

| Abstract: | The influence of ground rotation on rotational pick-ups is presented in this paper, which is too small to be measured for almost all of the widely used accelerators because of the short conversion pendulum length. It is impossible to obtain the rotational component from the accelerators'records of strong motions, because the rotational component is small in pendulum output. Two rotational pick-up schemes, gyro scheme and double-pendulum scheme, are presented in this paper. |
