| 单词 | susceptibility |
| 释义 | susceptibility 1(magnetic susceptibility) Symbol Χm. The dimensionless quantity describing the contribution made by a substance when subjected to a magnetic field to the total magnetic flux density present. It is equal to µr - 1, where µr is the relative permeability of the material. Diamagnetic materials have a low negative susceptibility, paramagnetic materials have a low positive susceptibility, and ferromagnetic materials have a high positive value. 2(electric susceptibility) Symbol Χe. The dimensionless quantity referring to a dielectric equal to P/ε0E, where P is the electric polarization, E is the electric intensity producing it, and ε0 is the electric constant. The electric susceptibility is also equal to εr - 1, where εr is the relative permittivity of the dielectric. |
