By using the scenic beauty estimation of psychophysical paradingm,the landscape of outer ring road in Qinhuangdao was assessed,and correlation analysis was conducted.

Stress analysis and strength evaluation of high pressure reactor;

Finite Element Calculation and Strength Evaluation of the Local Stress in the Support Locations of Vessels;

Retention and strength evaluation of the concrete sample;

With regard to dangerous section, the strength assessments were carried out.

The article points out that strength assessment is an important link to evaluate the qualification of concrete strength,and discusses problems easily appeared in the division of acceptance batches and the assessment of the standard maintaining test block and maintaining test block with same conditions,in order to give out accurate assessment on batch-acceptance concrete.

Elastic-Plastic Analysis and Intensity Evaluation of the Nozzles of 112E/G Heat Exchangers;

It is contrasted with the orthogonal open structural distribution and intensity evaluation is conducted on its tangential opening tubing connection according to JB 4732 analysis and design criterion.

The intensity evaluation was completed by the stress classification method.

Construction and accuracy evaluation of GPS/VRS positioning system with a multiple reference station network;

Based on this modified Hatch-type filter and precise ephemeris,the accuracy evaluation of satellite clock bias of broadcast ephemeris using GPS dual frequencies phase-smoothed pseudo-range is researched.

The accuracy evaluation technique has been developed for the height anomaly at any point which is located in a local GPS leveling gridded network.
