炭化速度 meaning in Chinese

charing rate

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
结果表明：火灾发生过程中未处理木材、阻燃浸渍处理和涂刷防火徐料木材内部温度上升过程出现5个阶段；经过阻燃浸渍处理和涂刷防火涂料后，木材的燃烧炭化速度降低了21 . 1 % ~ 35 . 6 % ，内部温度上升速度大幅度下降；白皮松木材的燃烧炭化速度比水曲柳木材的燃烧炭化速度快8 . 5 % ~ 17 . 4 % ；未处理木材沿弦向的燃烧炭化速度比径向快5 . 8 % ~ 10 . 5 % ；木材内部的温度变化沿燃烧推进方向不同而不同。
