This paper uses macroeconomic method to analyse the house price changing, the study shows that the price changing is relation with the per capital GDP and per expend, by using the elasticity of residential property prices, it also analyses the direction of house price changing.

A Study on Evaluation of Relative Strength for Different Polymer Gels Used at Oil Fields;

The early-age relative strength-simplify maturity equation was concluded from this research and the relative strength when simplified maturity reached 600d was discussed.

Based on the preliminary researches on tube clearance, overdistension measure, total distension measure, weld relative strength, destructive pressure test in producing copperaluminum combined columnwingtype radiator, discusses crucial skills to improve the technical and provides the basis for manufacture and standardization of the radiator.

Observations of the relative intensity of the Zeeman effect of Hg and measurement of the Landé g-factor;

Determination of relative intensity for Zeeman spectrum line of HgI;

At first, the authors numerically calculate many apparent polarizability sounding curves of various IP ore bodies below undulatory terrain by using the improved 2 dimension finite element program, then present the relative intensity method locating the target on mountainous districts for Fixed Point Source Sounding(FPS).
