ased on the theory of errors and practices of weighting in urban land classification, the standard error and the accuracy of the estimation of the classification factor weights estimated by AHP and Delphi is analyzed.

In fuzzy comprehensive evaluation,how to decide factor weights is very important but difficult,which involves the rationality and authenticity of eveluation results.

This text applies AHP to appraisal factor weights assessing problem in the job evaluation,has very strong operation and offer the reliable basis for scientific management in the enterprise.

Revision on solution of the renormalization group for Ising model with weight factor;

Meanwhile,quasi-weight factors for classification were adopted to resolve problems of classification error due to imbalance of sample types and numbers.

This algorithm is simple and independent of initial states, the value of weight factor can be self adaptively decided.

Expressing weighting factor in terms of refractive index to study multi-layer mirrors;

And the smoothed precise of Hatch filtering is higher than any other methods when the effect of phase-smoothed pseudo-range with different weighting factors are analyzed.

Finally a method is put forward to improve the front-end load through setting Weighting factor.

With the introduction of Vapnik s ε-insensitive loss function and the new weight factors, the new objective function is re-constructed, and consequently, its new update rules are derived according to the Lagrangian optimization theory.

A new method is applied in this article to the quantitative phase analysis for weight factors of X-ray diffraction intensity.
