It shows that the reaction of IC with lignin mainly produces carbamate, when lignin contains some water, produces weak carbamide; but the reaction of IC with wood powder produces weak carbamite, and with the wood powder containing water mainly produces carbimide.

对于异氰酸酯与木材及其组分反应产物的结构,论文采用傅利叶红外谱图进行了分析,结果表明,木素与异氰酸酯反应主要生成氨基甲酸酯,含水率较低时有少量取代脲产生;木粉与异氰酸酯反应生成的氨基甲酸酯较少,含水木粉与异氰酸酯主要生成取代脲。

At the same time, a continuous restraint on the edaphon, including those existing in the tested roots will happen when 50g wood vinegar are added into 1kg organic manure and 30kg soil.However, the influence of pyrolignerous acid and guaiacol were not same with wood vinegars. The reason that wood vinegars can much active the edaphon effectively, is not only the pyrolignerous acid or guaiacol reacted.

此外,通过采用木醋液中的两种主要成份醋酸与愈创木酚对比试验,表明其对土壤微生物数量的影响与木醋液不相关,木醋液能起到增加土壤微生物数量的作用,虽然有可能是其他物质在起主导作用,但更有可能的是多种物质的综合作用。

This article also discusses neutrosphere and reversion of the flectional wood by using mechanics knowledge and obtains function on length of the compressing wood after reversion.

By analyzing these data,it was concluded that:1The combustion of wood,including rate of heat release,total heat release,effective heat of combustion,mass loss rate,smoke ratio,specific extinction area,concentration of CO_2 and the yield of CO_2Y_(CO2,were decreased considerably by the treatment of FRW;2There is a strong synergistic effect of fire retardance between GUP and boric acid;3The trend of MLR curve of FZ was similar to its RHR curve,weight loss and heat release were happened mainly in flaming phase;4Char formation of wood was markedly accelerated by FRW,which indicated that catalytic charring effect of FRW on wood is the primary side in its fire-retardation mechanism.

对于组成和结构变异性很大的木材而言,由于CONE实验所使用的样品量相对于其他分析方法要大得多,因而实验结果比较有代表性。此外,CONE实验可在模拟火灾条件下进行,这是该方法的又一突出的优点[5~6]。木材阻燃剂FRW主要由磷酸脒基脲和硼酸组成,此外还含有

为了弄清楚不同化学试剂处理引起木材内部分子构造的变化及其分子的运动状态,该研究针对杉木试材,采用动态粘弹性分析仪,测定了含水率在纤维饱和点状态下脱木索处理木材、DMSO处理木材和非晶化处理木材以及素材,在-100—10℃、0.5-10Hz的动态粘弹性。

In order to provide an overall understanding on the basic theory and previous researches of wood chemical rheology, the author discusses some respects on the basis of the common knowledge of deformation and flow, which served as the foundation of wood chemical rheology. These respects include the results by Stein and Tobolsky, such as the correlation between the change of polymolecular structure and stress relaxation, the classification of physical rheology and chemical rheology, the difference between the research on wood chemical rheology and other methods, as well as a kind of non\|continuous method to measure stress relaxation proposed by Tobolsky \%et al.

Points out that the switching frequency、the input inductance and the output power all have great contribution to the input-current THD. When the output power goes up, the input current harmonic content keeps almost constant, thus the THD goes down.

指出开关频率、输入电感和输出功率对输入电流THD有显著影响,发现整流器输出功率增加时,输入电流谐波含量基本不变,从而输入电流THD减小。
