In conclusion, the lag phase of Streptococcus thermophilus was shorten in the eutrophy culture medium, and the time achieving the culminated point of logarithmic phase was shorted also, at the same time, the stationary phase lengthened. After secondary culture, Streptococcus thermophilus reached directly the log phase hardly through the lag phase, and then quickly reached the decline phase. There were more relations of the metabolic regalities of the three kinds of nutritive substances with the super-concentrated incubation process of Streptococcus thermophilus: the more the number of the bacteria, the quicker the metaboling, while the fewer, the slower the metabolism. Moreover, there apparently existed morphologic changes in this course, and there maybe existed the apoptosis, which correlated with bacteria propagation and acid producing. With the culture time postponed, the nutritive substances in the culture medium lacked also, and the morphologic change and apoptosis appeared more obviously.

When meteorite hit the Earth surface, it created shockwave to transfer the kinetic energy to the Earth surface. When the speed of meteorite strike reached 10 km/second, the pressure of shockwave can reach several millions bar to compress the target terrane to produce heat, the effect of impact deformation caused by it is several scales stronger than rock intensity, the granite would melt down once the pressure of shockwave reached about 500 thousands bar, the granite would gasify (solid became liquid and meanwhile further became gaseity) once reaching over 600 thousand bar.
