Don) planted at Gobozawa in Tokyo University Forest in Chiba were tested. Five logs were used. The tests and the measured properties were as follows: 1) Soft X-ray measurement: density variation in the radial direction 2) Static bending test: Young's modulus, proportional limit, bending strength, and bending work 3) Impact bending test: absorbed energy in impact bending 4) Compression test: Young's moduli in longitudinal (L), radial (R), and tangential (T) directions, proportional limits in L, R, and T-directions, and longitudinal compression strength 5) Torsion test: shear moduli of the LT and LR-planes 6) Shear test: shear strength of the LT-plane 7) Hardness test: hardness of the RT, LT, and LR-planes 8) Shrinking test: percent shrinkage in the L, R, and T-directions The results were as follows: 1) The patterns of variation of the measured wood properties in the R-direction (from pith to bark) mainly followed pattern (a) but some cases followed pattern (b). a) Around the pith: the values of the properties increased or did not change in most cases, and sometimes had peaks. Heartwood region, and boundary between heartwood and sapwood: the properties exhibited peaks. Sapwood region: the properties decreased. b) They were stable at the pith and heartwood regions. 2) The pattern of variation did not change with the diameter of the logs. 3) The wood properties were related to density and moduli of elasticity at the 1% or 5% significant level in almost all of the cases.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"54299","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KUBOJIMA,
