6827 .Due to the quantity value transfer ,beats by dre detox (http://www.beatsbydrepascher.eu),error is increased by degrees ,in the error table when ,according to root mean square error synthesis ,but also by other methods of synthesis ,many methods, are not unified ,that is not a standard ,the evaluation of measurement result reliability lost scale ,this is very adverse to j ?The author is aimed at this problem ,discusses the display value itself the standard deviation and the standard deviation of measurement result of distinction and connection, and derived the calculating the standard deviation of measurement result of the synthesis of formula (3 ),( 4)and ( 5).
The standard deviation is equivalent to the International Bureau of weights and measures recommended units into a formula of class B standard deviation .So B type standard difference is caused by the instrument itself ,is increased by step passed down .
Class A and class B standard deviation standard deviation is different, it is using the same instrument had same amount Q ,under normal conditions permit, after repeated measurements ,and error ,it is with the statistical properties of the .
Measurement error from the class A and class B error table is objective .Definition of the standard deviation of measurement result for rJ=J Σ +sigma .This for a horizontal table ,namely to establish baseline calibration system and the calibration system, this method of synthesis is reasonable ,scientific .
