A simple prediction of completion time on preservation of archaeological waterlogged woods by wood dimensional and weight measurement

考古学中的湿陷木退化诊断在追求简单化的新发展中，由于研究的简化和可靠性的提高，评估可以客观和定量化。另外，很明显，通过使用设定为-80℃（预冻温度）的真空冷冻干燥工艺进行快速冷冻，考古浸水木材与常规的-40℃冷冻相比，可以获得良好的尺寸稳定性。

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.
