摘　　要：通过对2010年8月初克拉玛依台与和丰台仪器对调前后台址背景噪声的计算和对比,得出,克拉玛依台仪器对调后短周期台址背景噪声RMS由24.7Counts减小到16.2Counts,远震初动波形比没换仪器前更容易辨认。这次对调仪器有助于克拉玛依台观测质量的提高。Through computing and comparing the background noise before and after the exchanging of the seismograph in Karamay and Hefeng seismic station in August,2010, we found the short cycle background noise of Karamay （RMS） reduced from 24.7 counts to 16.2 counts when the instrument had been exchanged. And it is easier to recognize incipient teleseism wave-form than using the old instrument. So the exchanging is helpful to improve the observation quality of Karamay seismic station.
