摘　　要：对陆态网络腾冲台2012-07-01~2013-06-30连续重力观测资料进行处理,获得该台站观测精度及噪声水平。结果表明,腾冲台1~100s噪声水平在9×10-8 ms-2左右,100s^100min噪声水平在0.3×10-8ms-2左右,白噪声水平为0.509×10-8 ms-2,对O1波、M2波等主要潮波振幅因子测量精度达到SG-053超导重力仪的观测量级,其中M2波振幅因子测量精度最高(为0.000 18)。腾冲台可为川滇地区强震和腾冲火山活动监测、震前重力变化及相关研究提供高精度、可靠的连续重力观测资料。The observations of Tengchong continuous gravimeter of CMONOC from July 1,2012 to June 30,2013 are analyzed.In addition,its precision and noise levels are obtained.The results show that the noise level of Tengchong station from 1sto 100 sis about 9×10^-8 ms^-2,and from 100 sto 100min is about 0.3×10^-8 ms^-2,while the white noise level is 0.509×10^-8 ms^-2.The precision of main tidal factors（such as O1 and M2）extends to the superconducting gravimeter SG-052 used at observing stations of the Gravity Network Center of China.M2 has the highest precision reaching 0.00 018.Tengchong continuous gravity observation can provide high precision and reliable continuous gravity data for studies about strong earthquake monitor,volcano movement monitor and gravity change before earthquakes in the Sichuan-Yunnan region.
