摘　　要：从微震仪标定的基本公式出发，以误差理论为基础，以ＤＤ—１型地震仪为例，导出标定中各因素对标定精度的影响；并用概率统计方法，对标定精度做了比较符合实际的计算，进而提出了提高标定精度的改进措施。In this paper, the effect of every factor on calibratiion precision has been analyzed based on the basic calibration formula of microseismograph and the theory of errors, and the calibration precision was calculated using probabilistic method that was more conformed with the actual situation. Then an approach to improve the calibration precision of microseismograph has been provided.
