In order to make clear the regulation of the combustion and the heat - transport process of fire - retardant treated wood , the combustion of untreated , fire - retardant solution soaked , and fire - proof paint coated white pine ( pinus bungeana ) and northeast china ash ( fraxinus mandshurica ) wood as well as the rising process of temperature at different sites in wood were measured in this study , taking a multi - function fire - proof experiment oven to simulate the typical process of fire 摘要為了弄清楚阻燃處理木材的燃燒及其熱傳導規律,該研究采用多功能耐火實驗爐模擬典型火災的發生過程,測定了未處理、阻燃劑水溶液浸漬處理、涂刷防火涂料白皮松和水曲柳木材的燃燒及木材內不同位置的升溫過程。

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、阻燃浸漬處理和涂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涂刷防火涂料后,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。

The company has been established in 2001 , has the self - management import and export power , uses the advanced technology and the management pattern , the production camphor tree pine , the white pine , wooden material , combines and so on the woodware 公司成立于2001年,有自營進出口權,采用先進的技術和管理模式,生產樟松、白松、楊木集成材、拼板等木制品。

It can roar through the leafless oaks and shout down the hillside , and it can murmur in the white pines rooted among the granite ledges where lichen makes strange hieroglyphics 它在山坡呼嘯著光禿的櫟樹,它在植根于布滿曲折青苔花崗巖的五針松下低語。

He graduated from white pine high school in ely 1963 , getting mostly c ' s , d ' s and f ' s 1963年他從厄麗的白松高中畢了業,各科成績多是c , d或是f 。
