A drying storage according to the present invention can be carried or moved by a user or installed as a built-in in the user's residence, and can maintain an object in a dried state after drying the object to be dried, so that the convenience of use can be improved, wherein a desiccant material with an equilibrium moisture content suitable for the temperature and humidity conditions in which the drying storage is used, is applied so that the inside air of the drying storage is inhaled during a dehumidification operation to allow sufficient dehumidification and the outside air of the drying storage is inhaled during a regeneration operation to enable sufficient regeneration of the desiccant material.

The application provides a prestressed wood structure tension loss evaluation method and device, including the following steps: obtaining key parameters of the prestressed wood structure, and collecting temperature and relative humidity of a service environment; calculating the equilibrium moisture content of a wood surface based on the temperature and relative humidity, using a one-dimensional moisture diffusion model to combine the equilibrium moisture content as a time-varying boundary condition, and solving to obtain the internal moisture content distribution of the wood component; updating the elastic compliance of the wood according to the moisture content distribution, and combining the change rate of the prestress to calculate the elastic strain of the wood component. The application decomposes the total strain into four components with clear physical meaning, i.e. elasticity, pure creep, mechanical hygroscopic creep and hysteresis environmental strain, and sets differentiated parameters for the along-grain and across-grain components, and for the first time realizes quantitative analysis of the contribution of each factor in the evaluation, so that the main control mechanism of the prestress loss can be revealed, and direct theoretical basis and decision support for structure optimization design and preventive maintenance are provided.

This invention provides a polarizing plate that suppresses the decrease in transmittance under high-temperature conditions. The polarizing plate includes a polarizing element in which dichroic pigments are adsorbed onto and oriented in a polyvinyl alcohol-based resin layer, and a transparent protective film laminated on at least one side of the polarizing element. The polarizing element and the transparent protective film are bonded together by an adhesive layer formed from an adhesive containing a quaternary ammonium salt. The moisture content of the polarizing element is above an equilibrium moisture content of 30% relative humidity at 20°C and below an equilibrium moisture content of 50% relative humidity at 20°C.
