To control the flow in the high density area in the upper part of the tank the TES is used to spread the stock evenly on the top surface and to create a uniform down flow.

And combine control mining method, surface subsidence preplan theory, mining landslide area disaster forecast and numerical simulation studied out controlling mining estimate measure.

This paper comprehensively reviews the application of specific surface area analyzers and thermal analyzers in the quality control of soft ferrite materials.
