초록
This experiment was carried out to investigate the crack of coated Nitrocellulose Lacquer on flatand edge-grained boards of Quercus acutissima, ring-porous wood, and Betula platyphylla var. japonica, diffuse-porous wood, by variations of moisture contents at 7, 13 and 21%. Cold check system was used as an accelerating method for crack development, in which one cycle of the system consisted of 10 replications of each unit cycle,
