model balls falling through fluids. Abaid, Adalsteinsson, et.al. Abaid, Adalsteinsson, et.al. (1) explored the motion of falling spheres in strongly stratified flu-ids, in which their equilibrium density field varies with height. Similar to oceans or lakes, its fluid transitions are from low density at the top to high density at the bottom.

Ball milling is an efficient way to produce TiC steel bonded carbide. In addition to the use of alloy steel ball, a certain amount of cylindrical object are used for grinding medium and the content is 0, 15%, 30%, 50%, of the total grinding body, respectively. The results show that average size of particles became smaller with an increase of the content of cylindrical grinding medium.
