Deterioration Character of Aged Timbers
Open accessAbstract
重要文化財福勝寺本堂に用いられていた垂木で，施工年代が異なり（1500，1662，1836年頃），品等・使用環境が似通ったものの劣化調査を実施した。供試試料は全てアカマツである。ケブカシバンムシによる食害が，古い材ほど著しく進んでいた。食害部分を除いた，木材実質の経年変化を検討するために，未被食部のみを取り出して供試した。古材未被食部の酸化開始温度，および微小試験片の縦方向引張ヤング率は，現代材より低い傾向にあったものの，経年によって低下の程度が増すとは断定できなかった。未被食部のＸ線回折から求めたセルロース相対結晶化度には経年による増大の傾向が見られ，縦方向引張ヤング率との間に，弱い負の相関が見られた。また古い材ほどホロセルロース率が低下する傾向があり，経年による未被食部の成分変性を示唆していた。木材実質そのものの変性よりはどちらかといえば虫害の方が，実用上の性能低下に大きく影響すると考えられた。

Claims other papers make about this one
Each is checked against this paper’s own text: does it say what the citing paper says it does?
The source backs part of the claim, not all of it — or backs it for a different population, condition or comparison.
In the citing paper
“Additionally, other authors report no significant variation in crystallinity between aged and new wood of hinoki [70] or for other wood species [28,32,71].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
