The principle and design method of rotating flat display screen based on mechanical scanning are presented,and the homogenization algorithm of image is also presented with the inhomogeneous problem of pixel distribution considered.

With a design scheme of DeNOx reactor the impact of the non-uniformity of reagents in flue gas on performance of DeNOx system is simulated.

A graphic method is adopted to demonstrate how the non-uniformity is caused.

3D Numerical Simulation of Intake Unevenness for Engines;

Simulation Study on Charge Unevenness for Air Intake Manifold Construction

With two foil gauges stuck on each prestressing tendon, discussion is made about the tensile stress unevenness of prestressing tendons on two tests of one-by-one-tendon stretch and 4-tendon simultaneous stretch individually.

The concept of the heterogeneity of CRM has been put forward.

The differences in density,hardness and microstructure of these samples were studied, and the difference in density,hardness and microstructure at different position of sample was investigated and the reason for heterogeneity was analysized.

For the heterogeneity of asphalt concrete pavement, analysis has been made on causes of some initial failure phenomenon, and control measures for the heterogeneity of asphalt concrete pavement have been proposed, such as that the broken stones should be prepared according to the requirements of the construction, and the broken stone should be screened again in the construction site etc.
