【摘要】 分析了精密补偿器水准仪磁致误差的成因，介绍了研制的一套磁致误差检测设备以及完整的检测方法。通过大量的检测数据与数理统计，表明４测回的标准差为０．００８″。该设备已为全国一等水准网复测，地震形变测量和精密工程测量等检测磁致误差１００多台次。更多还原

【Abstract】 On the basis of analyzing the cause of magnetic error of precise compensator level,it is recomended that a set of magnetic error testing equipment is developed and an integral test method is formed.Through the tests with a great deal of data and the result of mathmatic statistics,it is shown that the standard deviation of four observation sets is 0.008″.The magnetic errors of precise compensator levels are tested more than one hundred sets/times for releveling of national first class net,crustal deformation survey and precise engineering survey and so on.更多还原
