%X The mixed calibration of 8 LCR and 4 CG-5 gravimeters carried out on the long baseline including 4 high precision absolute station of Wuhan,Zhengzhou,Beijing and Shenyang from May 5th to May 20th,2010 and from Jan 18th to Jan 26th,2010 is introduced.The results show that the quadratic terms exists in five gravimeters including all the 4 CG-5 gravimeter,but the precision of them is relatively low.If we only calibrate the first order term,the precision of the first order term of the five gravimeters is better than the joint calibration and for the other gravimeters it is basicallly invariant.
