Abstract

The law of precision loss about dynamic measurement system is studied in this paper. Its total loss accuracy can be obtained by transformation law of its errors in different measuring phases of a certain measuring period. Based on the total precision loss and its structural characteristic, WNN is used to decompose systemic total precision loss and trace to its inside structural units, and build precision loss function model of structural units. So precision loss disciplinarian with all units and infection of different unit to total precision loss is definitude, the principal infection unit to systemic total precision can be distinguished. In the end of the paper an application examples have been introduced.
