查询词典 drying method

The free water in wood is very closely related to the density change of wood during drying, so that the sound speed measured by tap tone completely obeys the physical law relating sound speed and properties of solid materials. 2. When moisture contents are higher than the fiber saturation point, the weight changes or the moisture content changes of the wood can be estimated with high accuracy by measuring the changes of sound speed using the tap tone method.
