A uniformization method for the modal analysis of an extra large construction is presented when this construction is divided into many parts and the ambient vibration measurements on each part is carried out on different date.

Recursion method, and the calculation on magnetism of clusters;

2 crystal and amorphous alloy was studied by recursion method.

Study on incorporation method of cutting-plan of custom-made garments;

An iterative least square method was used for the evaluation of standard Gibbs free energy for the formation of silicate minerals in order to remove some of the limitations of the earlier exponential regression method.

Aiming at generalized maximum entropy(GME) regression effect and especially the indetermination of the choice of support space of parameter and error in the model,the modelling process of GME regression method is analyzed,and its regression effect is compared with others effects through two cases in this paper.

While transmission attenuation islarge,the convergence and stability of used regression method seem very important.

On the basis of the fatigue cumulation damage equivalent theory,and through reliability tests,a new kind of aircraft vibration environment data induction method is proposed.

Then the validity of further extension of fuzzy reasoning based on resolution is discussed.
