As one of the most stringent components in diesel engine, piston transfers the drivingforce during its high-speed reciprocating motion and withstands high mechanical load and thermal load.
When unstable thermal conditions are satisfied with the constituent fluctuations of "correct direction" and "degree", phase transformation drivingforce is raised and nucleation is promoted.
当成分起伏的“方向性”和“程度”满足形核的热力学条件时，相变驱动力增加，可以促使钢液形核。

The formation of sedimentary basin is mainly related to the thermal and material convection of the earth interior, and that is the primary drivingforce causing the formation of sedimentary basin.
