This study focuses on the thermal insulation and moisture absorption and desorption characteristics of wooden materials used in specimen storage boxes for museum artifacts in regulating temperature and humidity effects, and their effects on the stability of relative humidity with mixtures of hygroscopicconditioning materials. Its findings are as follows: Judging from the adjusted index of known temperature and humidity in storage boxes for museum artifacts, wood is superior to inorganic materials on the control of humidity and temperature. Wooden storage boxes contribute to the stability of the micro-environment inside the box; consequently, it is suitable for storage of specimens. After the addition of hygroscopicconditioning materials, as the W / V increases, the reduction of the relative humidity in a stainless steel storage box demonstrates a curve until the W / V is 3.41 kg/m3, after which it becomes flat. As the W / V ratio increases, the Taiwan red cypress (Chamaecyparis formosensis Matsum .) and Western hemlock (Tsuga heterophylla Sorg ) storage boxes decreases the relative humidity, but no significant improvement is obvious.
