| Abstract: | Determination and elimination of the instrumental crrors are very important for improvment of the observing precision of the meridian circle. In this dissertation, the observational principle and the instrumental frame of the LLMC are briefly introduecd. The sourecs of various instrumental errors and the method of determination and hande of them are discussed thoronghly. In order to execllently determine the diameter corrections by the using combination method of the fixed angular distance, the method for improving the precision of determiation of the diameter corrections is studied and the formulac are derived. At same time, in consideration of the specific premises, the formulae are inspected with some data and the results are satisfactory. |
