The rockfill dam has strict requirements on rockfill materials, not only reduce the super-size materials and control the fine aggregates, but also have a good gradation [1].
Because Eq.3 assumed that blasting rockfill gradation fully complied with Talbot distribution, then rockfill materials were strictly self-similar.
Primary rockfill materials adopted till conglomerate.

Magnetic materials include isotropic and anisotropic materials.
After being magnetized, the magnetic properties of the anisotropic materials are better and the remanence on the surface of the magnet is more than the isotropic materials.
Thus, the anisotropic materials are more applicable to the parallel magnetizing of the bipolar magnet steel in this design so as to increase the air-gap length of the tracking position sensor, while the isotropic materials are more applicable to the radial charge magnetism of multipolar magnet steel.
The ring or cylindrical magnet steel of anisotropic materials need to be magnetized in the parallel magnetic field, where the direction of the parallel magnetic field should be consistent with the magnetic orientation direction of the magnet steel, as Fig.2 shows.

Material models.
This suggests that the FE model may not fully capture the thermal insulation properties of the wall's unexposed side, which could be due to taking standard values for the thermal properties of the constituent materials (especially thermal conductivity) and not incorporating the actual/tested thermal properties of the materials since they are not mentioned.

The obtained nitrogen-doped mesoporous carbon (NMC) shows good capacitances as electrode materials for EDLCs.
The N2 adsorption-desorption isotherms of NMC materials are summarized in Fig. 1d.
The excellent performance makes NMC-5 as the promising electrode materials for the applications of supercapacitors.
