Key points of functional materials' properties

2.1 Conductivity

Conductivity is a fundamental property of functional materials, which refers to the ability of materials to conduct electricity. The conductivity of functional materials can be expressed in terms of resistivity, conductivity, and other parameters. When translating the properties of conductivity, you can use the following expressions:

Conductivity: It refers to the ability of materials to conduct electricity, usually measured in Siemens per meter (S/m) or ohm per meter (Ω·m).
Resistivity: It is the reciprocal of conductivity, which reflects the resistance of materials to current flow, usually measured in ohm per meter (Ω·m).
Permeability: It refers to the degree of material to be magnetized, usually measured in henry per meter (H/m).

2.2 Permeability

Permeability is another important property of functional materials, which refers to the ability of materials to allow magnetic flux to pass through. When translating the properties of permeability, you can use the following expressions:

Permeability: It refers to the degree of material to be magnetized, usually measured in henry per meter (H/m).
Magnetic susceptibility: It is the relative permeability of materials, which reflects the material's ability to be magnetized, usually expressed in the unit of dimensionless number.
Magnetic anisotropy: It refers to the anisotropy of materials in the magnetic field, which can be expressed in terms of the angle or direction of the magnetic field.

2.3 Optical properties

Optical properties of functional materials refer to the ability of materials to absorb, transmit, and reflect light. When translating the properties of optical properties, you can use the following expressions:

Absorption coefficient: It is the ratio of the absorbed light intensity to the incident light intensity, usually measured in cm^(-1).
Refractive index: It is the ratio of the speed of light in a vacuum to the speed of light in the material, usually expressed as a dimensionless number.
Transparency: It refers to the ability of materials to transmit light, which can be expressed in terms of the light transmittance rate.
Reflectivity: It refers to the ability of materials to reflect light, which can be expressed in terms of the reflectance rate.

2.4 Thermal properties

Thermal properties of functional materials refer to the ability of materials to conduct heat and store heat. When translating the properties of thermal properties, you can use the following expressions:

Thermal conductivity: It refers to the ability of materials to conduct heat, usually measured in watts per meter-kelvin (W/m·K).
Specific heat capacity: It refers to the amount of heat required to raise the temperature of a unit mass of material by 1 Kelvin, usually measured in joules per kilogram-kelvin (J/kg·K).
Thermal expansion coefficient: It refers to the change in length of materials per unit length when the temperature changes, usually expressed as a dimensionless number.

2.5 Mechanical properties

Mechanical properties of functional materials refer to the ability of materials to resist external forces and maintain their shape and size. When translating the properties of mechanical properties, you can use the following expressions:

Tensile strength: It refers to the maximum tensile stress that materials can withstand before breaking, usually measured in megapascals (MPa).
Yield strength: It refers to the stress at which materials begin to deform plastically, usually measured in MPa.
Elongation: It refers to the increase in length of materials per unit length when they are stretched, usually expressed as a percentage.
Hardness: It refers to the resistance of materials to indentation or scratching, usually measured by the Brinell hardness or Vickers hardness.

In conclusion, the translation of "How to translate the properties of functional materials?" into English is "How to translate the properties of functional materials into English?"
