We show that the rearrangement contribution of TBF to neutron and proton single-particle potentials is repulsive and increases rapidly with increasing density and momentum.
结果表明：三体核力重排效应对质子和中子单核子势均具有排斥性，而且其贡献随动量和密度增加而迅速增大。

The symmetry potential turns out to depend strongly on both momentum and density, while it is almost independent of the isospin asymmetry.
结果表明同位旋对称势对于同位旋非对称度的依赖性很弱，但对于动量和密度均有较强的依赖性。

The equations of axial momentum and radial momentum are made during the presented inflation of parachute, and the parachute opening load in low atmospheric density is studied on the basis of them.
