The paper tries to find a better method to solve the problem of analyzing riverbed evolution using geographic information system, and builds a riverbed evolution analysis system based on ArcGIS.

The volumetric heat transfer coefficients H_v between porous aluminum and air were measured by developing single-blow transient experimental technique in conjunction with the inversion analysis.

Based on the principle of inversion analysis, applications of inversion analysis in welding field including material properties, heat source model, boundary conditions were introduced.

Based on field measured information, a method for the inversion analysis of elastic constan.

Determination of thermal parameters of concrete by reverse analysis of test results;

Based upon the relationship, a reverse analysis is developed so that t.

The experimental data by least two-multiplication method regression analysis by in reverse analysis is adopted to study the relations between chemical reaction rate and curing temperature, as well as the concrete adiabatic temperature rise formula is expressed by equivalen.
