When a side of a single material layer with a sufficient thickness is subjected to harmonic heat, the ratio of the amplitude of the heat flow through the surface to the amplitude of the surface temperature is larger, the better the thermal stability of the material. The heat storage coefficient is a thermal characteristic of a material. In layman's terms, it is the ability of a material to store heat. In the book "Building Physics", the definition of the heat storage coefficient is: In building thermal engineering, the ratio of the amplitude Aq0 of the heat flux fluctuation on the surface of a semi-infinite thickness object to the temperature amplitude Af is called the material of the object under the action of harmonic Heat storage coefficient. The thermal storage coefficient of the material expressed in units of W / cm².k with S can be determined by calculation, and the thermal storage coefficient values ​​of various building materials can be obtained from “Code for Thermal Design of Civil Buildings” (GB50176).

When the side of a single material layer of sufficient thickness is affected by harmonic heat, the greater the value of the thermal flow amplitude of the surface and the ratio of the surface temperature amplitude, the better the thermal stability of the material. The heat storage coefficient is a thermal characteristic of the material, which is colloquially speaking the ability of the material to store heat. In the book "Building Physics", the coefficient of heat storage is defined as: in architectural thermomechanics, the ratio of the amplitude Aq0 of the temperature flow fluctuation of the surface of a semi-infinite thickness object is called the material heat storage coefficient of the object under harmonic action. The heat storage coefficient represented by S in W/cm2.k material can be determined by calculation, and the heat storage coefficient value of various building materials can be obtained from the "Civil Building Thermal Engineering Design Specification" (GB50176).

When one side of a single material layer with enough thickness is affected by harmonic heat, the larger the ratio of heat flow amplitude to surface temperature amplitude is, the better the thermal stability of the material is.
