1. Chemical denucleation is introduced to the study of undercooling.

2. Thermostatic type trap large undercooling, low emission pool water Redu, the use of low-temperature condensed water can be enough sensible heat, energy-saving motive is good.

3. Low undercooling degree, the rate high back press. On the heating equipments with condensed water and the recovery system engineering, even show its ascendant function.

4. As a result, the paper indicates that undercooling is the main factor that causes spherical graphite growth in the crystallization process.

5. The relation of microstructure evolution vs undercooling in Ni-Si eutectic alloy was systematically investigated.

6. Under the same undercooling, the higher the system pressure is, the worse the inhibitory effect is.

7. Uniform nucleations of pure metals during large undercooling are analyzed in present paper from the view of non-equilibrium.

8. With the same cleanness, the undercooling of high clean steel is smaller than that of pure iron.

9. Calculations demonstrate the formation of facets and anisotropic undercooling distribution along the interface.

10. The dependence of tip velocity on the melt undercooling was computed and compared with L-G-K theoretical model.

11. The reason causing bottom-shrinkage is that gravitational segregation results in unusual composition undercooling, the method to eliminate or ease bottom-shrinkage is given.

12. The different primary phases formed in the undercooled alloy melt were firstly determined as a function of undercooling by the microstructure analysis.

13. The dependence of simulation results on the space step, the initial nucleus radius, anisotropy and undercooling studied, and how to choose the values of these parameters is settled.

14. An explicit finite—difference method (FDM) was used to model and simulate the solidification of eutectic cast iron by combining heat transfer equations with undercooling nucleation and growth laws.

15. The main reason that rare earth cerium can improve elongation of ZA27 alloy is that cerium increases the compositional undercooling of the alloy.

16. This paper has researched on the effects of the system pressure, undercooling, inhibitors concentration, gas condensate and the methanol on hydrate formation kinetics.

17. The results of simulations indicate that the relationship between melt undercooling and box counting dimension of dendrite is close to parabola.

18. The growth velocity of the crystal depends on the undercooling(), temperature gradient and original particles in the precursor.

19. Finally, in the light of measured recalescence curves both the dependence of the fraction solid on time and the solidification rate on transient undercooling were determined.

20. The transformation rule of diameter of droplets between cooling rate and undercooling can be analyzed in drop tube.
