| Research Abstract |
In the new development of deterioration diagnosis of archaeological waterlogged woods in pursuit of simplicity, the evaluation can be objectively and quantitatively since studies of reduction and reliability improvement. Adds, it was clear that by use of rapidly frozen by setting to -80℃ (temperature of the pre-freezing) in a vacuum freeze-drying process, archaeological waterlogged woods can be good dimensional stability compared to freezing at -40℃ conventional.
