The critical shear stress unpinning the 60 dislocation from the ring-shaped hexagonal vacancy defect decreases as the temperature increases in the models, and approaches a stable value of 0.6GPa as the temperature is higher than 300K, bellow the misfit stress in common SiGe heterostructures, which indicates that the 60 dislocation can not be pinned by the ring-shaped hexagonal vacancy defects in this case.

When the flow through the balance of the piston damping the flow of holes increases, the balance of the piston, the next increase in pressure on both sides of a balanced increase in the distance the piston increases, and vice versa reduced; and also because the spring stiffness is very small, so that shift the balance of the piston pressure required very few changes, so the flow through the Poppet head is not much change, so the first opening Poppet very few changes, to mention the pressure of moving the first opening can be said to remain unchanged, that is, when the pilot valve spring after a set, Poppet Head was opened, the balance piston chamber pressure remained basically unchanged.
