radial wood 中文意思是什麼
radial wood
解釋
徑向木材-
The radial variation patterns of wood density in 19 chinese fir provenances were studied by means of x - ray wood densitometry
以微密度分析對19個種源杉木的木材密度徑向變異模式進行了研究。 -
The results showed that : there were five stages in the rising process of the internal temperature of untreated, fire - retardant solution soaked, and fire - proof paint coated wood during the fire ; the carbonization rate of wood decreased by 21. 1 % ~ 35. 6 % and the rising speed of internal temperature also declined greatly when wood was soaked in fire - retardant solution or coated with fireproof paint ; the carbonization rate of white pine was 8. 5 % ~ 17. 4 % higher than that of the northeast china ash ; for untreated wood, the carbonization rate in tangential direction was 5. 8 % ~ 10. 5 % higher than that in radial direction ; the internal temperature of wood varies with the developing direction of combustion
結果表明：火災發生過程中未處理木材、阻燃浸漬處理和塗刷防火徐料木材內部溫度上升過程出現5個階段；經過阻燃浸漬處理和塗刷防火塗料后，木材的燃燒炭化速度降低了21 . 1 % ~ 35 . 6 % ，內部溫度上升速度大幅度下降；白皮松木材的燃燒炭化速度比水曲柳木材的燃燒炭化速度快8 . 5 % ~ 17 . 4 % ；未處理木材沿弦向的燃燒炭化速度比徑向快5 . 8 % ~ 10 . 5 % ；木材內部的溫度變化沿燃燒推進方向不同而不同。
