强震动记录对于中国的震害防御、地震应急等防震减灾事业意义重大，观测数据质量日益受到重视。文中给出强震动记录质量相关概念的初步定义，包括强震动记录和记录过程的质量，总结了强震动记录中存在的不完整波形、奇异波形（非对称、加速度基线明显偏移和尖刺等）、信噪比过低现象等，并提出提高强震动记录质量的8项措施，以保证记录的完整性、一致性、准确性和时效性。
Strong motion records are of great significance for the earthquake disaster prevention and earthquake emergency in our country. Results and suggestions are as follows:(1) Preliminary definition of related concepts on strong motion records quality is presented, including the quality of strong motion records and recording process; (2) Such abnormal phenomena as incomplete waveform, low SNR, singular waveform (non symmetry, baseline offset and obvious acceleration spikes etc.) in strong motion records are summarized; (3) Eight measures are put forward to improving the quality of strong motion records in order to ensure records integrity, consistency, accuracy and timeliness.
