3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Bamboo and wood collection
A general term for bamboo and wooden cultural relics and bamboo and wooden components of other cultural relics collected by museums, libraries and other collection institutions.
3.2
moisture content
The percentage of water content to total dry mass of bamboo and wooden artifacts (3.1) in the collection.
4 Principle
The change of moisture content of bamboo and wood materials will cause the change of their capacitance and dielectric constant. By measuring the capacitance and dielectric constant, the
Determine its moisture content.
