0 any unpleasant thick soft substance, such as food that has been cooked for too long -- 烂糊食物；糊状的东西
1 If you describe something such as a book or film as mush, you mean that it is too emotional. -- （书籍、电影等）伤感作品，煽情作品
An equation like holds in the liquid and solid parts of the mush as well as the pure-phase regions.
First the smaller solid fraction decreases the latent heat that needs to be removed to grow a given depth of mush.
Because of the fine structure, remains close to 0 in the mush and the average heat content is, approximately, proportional to the liquid fraction.
In this mush, the temperature is between the solidus and liquidus.
Melting starts at nucleation sites when reaches the critical temperature 0 at these points, and a mush forms.
Then a macroscopic model for the mush is obtained by an averaging procedure.
After about two days, only 9 large crystals protruded down to the mush-liquid interface.
The conservation equations describing the interior evolution of the mush then have the form of forced diffusion equations.
