Due to the differently inherent correlation of the test samples,the key of the algorithm takes both factors of local and global error into consideration comprehensively,and takes values of the global error as dependent variable of function of changing step length,then changes learning rate dynamically.

A class of merit functions for the second-order cone complementarity problems and a global error bound;

in trust region method,we present a global error bound for the distance between a feasible solution and the optimal solution under the condition that the gradient vector of the objective function is strongly monotone.

The problems for attention in error calculation and judgement are analyzed to ensure the accuracy of bridge testing.

A statistical method was proposed for the error calculation of full width at half maximum (FWHM) of X-ray diffraction peaks from the "Strip-chart" diffractometer, while formulas describing the relations a-mong the intensity, shape and measuring conditions were used for that of "Digital" diffraction peaks.

The influence of the maximum deviation angle θ max  in the kinetic model on the interface shape and calculation errors is vestigated.

The additional calculation error of measuring gas flow capacity through planimeter calculating av- erage value between differential pressure and static pressure with dual bellows differential pressure flow capacity table is discugsed in this paper.

Adopt this method to construct an arbitrary sinusoidal signal which has the same frequency as the reference signal,use this sinusoidal signal to replace the reference signal,then the calculation error induced by the distortion of the reference signal can be eliminated.

The calculation error in predicting brake power increases with increasing engine speed and decreases with increasing pressure.
