英文摘要	There are 54 sites employed by ITRF2000 for ITRF2000 orientation. The deficiencies are obvious. First, these sites cannot well represent the rotation rate of the earth crust because there is no selected site in five out of fourteen tectonic plates and three of fourteen plates only have one site each. Second, the total angular momentum of the crust is non-vanishing in ITRF2000, even though it is declared that No Net Rotation (NNR) with respect to NNR-NUVEL1A is imposed on ITRF2000 construction according to the documentations of ITRF2000. So the NNR condition in conventional terrestrial reference system (CTRS) realization cannot be satisfied in ITRF2000. In this paper, the criteria of site selection for estimating the Euler vectors are suggested; the Tisserand system constraint equation in ITRF construction is derived; and as a product, the global plate motions can be obtained from the ITRF2000 construction.
