    摘要: The present invention relates to a method for the determination of the stresses occurring in wood when drying or being dried. With the method in accordance with the invention, electrodes are used to generate an electric field in drying wood in order to measure the electric complex spectrum using the impedance spectroscopy method while at the same time employing sensors to measure acoustic emissions from drying wood and using the results for calculating the parameters required for determining the stress state existing in the wood and for monitoring and/or controlling the drying process.
