undercooling造句
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.
