Region based segmentation methods for soot image;

The coal dust image is often corrupted by all kinds of noises during acquisition or transmission.

At the same time, the nanoparticles chains also have the connection effective in the matrix, when NCA are pulled out and make the matrix deform and crack, but the NCA can not be pulled out completely until fracture at the neck of t.

By calculating an example, the influence of neck width on the temperature and speed fields of glass flow is studied.

The function and configuration of fur- nace neck structure are described according to running state of domestic float glass furnace and two ways to improve neck structure are conceived , one is that the water-bag of neck is displaced by sluice brick , another one is that double-neck structure can be used for large capacity furnace .
