With the help of visualization tools,the mining for the association rule is done to a certain depth,and the usefulness and the certainty of the rule are evaluated with its support,confidence and lift.

Calculating models of mass action concentrations for KBr(aq),NH_4Br(aq) and ZnBr_2(aq) binary solutions;

After combining investigation of thermodynamic properties of binary metallic melts with their phase diagrams, it has been found that when the calculating models of mass action concentrations of metallic melts are formulated according to their main phase diagrams (i.

According to the coexistance theory of metallic melt structure involving compound formation, a calculation model of mass action concentrations for Fe C P, Fe Mn P, Fe Si P metallic melts is formulated for T =1 673 K.

Calculating models of mass action concentrations for Mg-Al,Sr-Al and Ba-Al melts and determination of their thermodynamic parameters;

It is well known that if the depth of interaction(DOI) within the crystal can be measured, the parallax error can be corrected and the resolution should be uniform throughout the field of view.

Using the mechanics concept and the temperature effect of bridge structure,the author pointed out the influence of deck pavement to structure temperature effect.

The accidents induced by the temperature effect are often serious.

This paper expounds the shrinkage effect and temperature effect of the concrete,and advances some measures for controlling the cracks of the concrete in the construction practice.

Due to its large span and the special requirement for structural safetyt,he nonlinear stability of the dome was studied after regular design of static load and temperature load.
