For manufacturing the important equipment for Sanxia project,measurement instrument was urgently needed to measure the planeness error of the Big Mirror(a part of thrust bearing). But now,there is no good method for the measuring of planeness of high precision large plane. A research for one good method for Sanxia Big Thrust Bearing Plate planeness error measurement was done and described in this dissertation.
According to the requirement of Sanxia Big Thrust Bearing Plate planeness mea...
