The law of the change of the combination mass transfer coefficient α was studied for the adsorption of different gases by different coal rank samples under different pressures.

High complex heat-transfer coefficient (HCHTC) and low resistance coefficient (LRC) is the important economic technical indexes for heat-exchanger, To realize HCHTC and LRC, various measures are introduced.

CFD simulation on complex heat transfer coefficient of a mechanically ventilated airflow window;

It was shown that the particle diameter has the greatest effect on complex heat transfer coefficient, but rotational speed has the smallest.

According to the test results of heating systems in seven residential quarters, calculates the heat loss through open windows using the integrated heat transfer coefficient of buildings.

Discusses the influences of the shading and airspace width on the integrated heat transfer coefficient.

Simulates and calculates integrated heat transfer coefficients and design cooling and heating loads for different facade buildings by Window6.

By analyzing the problems with quality management in the company, it is proposed that "comprehensive quality coefficient" included in output evaluation should be introduced to solve the contradiction between output and quality in the process of production and to handle properly the relationship between quality, output, and efficiency.
