| 摘 要： | 以天宝岩长苞铁杉林内倒木为研究对象,结合以负荷量和含水率为自变量的综合燃烧属性及以灰分、热值、含水率及氮含量等理化性质为评价指标的燃烧熵值,综合探讨长苞铁杉林内倒木的燃烧性.结果表明,天宝岩长苞铁杉林内倒木属于低燃烧性可燃物,其发生火灾的可能性较小；长苞铁杉+糙花少穗竹混交林内倒木的燃烧性最低,非防火期长苞铁杉+毛竹混交林内倒木的燃烧性最大；倒木负荷量、综合燃烧属性值及发生火灾的可能性随腐烂等级升高而降低,平均含水率随腐烂等级增加而升高,燃烧性熵值随腐烂等级升高而降低.

| Abstract: | The adsorption and desorption performances for procyanidins from mangosteen shell were studied in this paper. The optimum resin was selected from ten macroreticular resins, and the static adsorption and dynamic adsorption conditions for it were studied. The results showed that XDA-7 resin was the best for procyanidins from mangosteen shell and the optimal conditions were as follow: adsorption flow 2 BV/h, elution agent(ethanol)concentration of 60%, and washing flow 2 BV/h, elution agent volume 6 BV. Under the proposed conditions, the purity of procyanidins from mangosteen shell was 66.20%. |
