96H LC 0,96 h LC 50 ,and 96 h LC 100 of twelve chemicals of phenol ,alkyl benzene and nitrobenzene,and three water samples to sword fish(\%Xiphophorus helleri)\% and rare minnow(\%Gobiocypris rarus\%) were tested.3. The phenol ic waste water was purified through the absorption of polyvingl pyridine.

介绍了含酚废水与聚乙烯基吡啶类树脂接触，酚类会吸附在树脂上，使废水得到净化，然后将吸附了酚类的树脂加热处理回收酚，与此同时，对树脂也进行了再生处理，再生后的树脂可循环使

And in this resin most of the phenol was free, that was to say it didn't co-condense with UF species, MF species, and even formaldehyde. So the method to add phenol to MUF resin in the end of the preparation of MUF resin couldn't guarantee the co-condensation between MUF resin and phenol to come forth.

另外，几乎所有的苯酚在树脂中也都处于游离状态，它既未与UF树脂或MF树脂发生反应，也未与游离甲醛发生反应，因此，在树脂合成后期向树脂中加入苯酚的方法不能保证共缩聚反应的发生。

By chromatographic techniques. On the basis of physico-chemical properties and spectral data, they were identified as α-amyrin,α-amyrin acetate, 27-hydroxy-α-amyrin,β-amyrin,β-amyrin acetate, ursolic acid,β-sitosterol, dauricine, emodin.

中分离得到9个化合物，通过理化性质和光谱分析，分别鉴定为：α-香树脂醇，α-香树脂醇乙酸酯，27-羟基－α-香树脂醇，β-香树脂醇，β-香树脂醇乙酸醇，熊果酸，β-谷甾醇，β-胡萝卜甙，大黄素。

Result:Characteristics of the tangentical longitudinal section of stem with resin and surface view of leaves were elucidated.Besides xylem vessels and fibers of the stem,it was found that the red resin also exists in the cortex parenchyma cells of the stem and the medulla and xylem of the root.According to the HPLC fingerprint analysis result of the stems with and without resin,a number of flavones and stilbenoids were detected in the stem in which resin appeared after it wounded.

结果：阐明了含树脂茎的纵切结构以及叶的表面观特征；除了茎木质部导管和纤维中有树脂外，发现剑叶龙血树受到损伤之后在茎皮层薄壁细胞、根的髓部和木质部亦有树脂的分布；含树脂茎和无树脂茎的指纹图谱显示剑叶龙血树茎在形成树脂后的化学成分中出现了较多的黄酮类、茋类成分。

Unsaturated polyester resins are the most widely used resin type for composites, comprising in excess of 80% of all thermoset resins (others being epoxies, phenolics, acrylics, imides, and urethanes).

不饱和聚酯树脂是复合材料使用树脂类型中应用最广泛的一种，也是热固性树脂最常用的一种（其它种类热固性树脂包括环氧树脂、酚醛树脂、丙烯酸树脂、酰亚胺树脂以及氨基甲酸乙酯）。

DSC thermo-analysis showed that both of epoxy resins and blended resins had an exothermic peak during the period of thermal-scanning due to the curing reaction. Comparison between different kinds of liquefied wood, blending resins that using the liquefied Japanese cedar of LW-C as the raw material would undergo more degree of cross-linking reaction. They released more reaction heat, and formed a more complete cross-linking structure. However, heat treatment could promote an advanced cross-linking reaction of room temperature cured resins. DSC isothermosetting analyses showed that the curing reaction of both epoxy resins and blended resins conformed to Arrhenius kinetic model. The time needed to achieve 95% of curing reaction was shorter for blending resin than that of epoxy resin.

由DSC热分析显示环氧树脂与掺合树脂在热扫描过程中均出现硬化反应放热峰，其中以液化柳杉LW-C为原料之掺合树脂在硬化过程可进行较多之架桥反应，其反应放热量较大，硬化树脂之架桥结构较完整，而加热可促进常温硬化树脂进一步之架桥反应；由DSC等温硬化性分析显示环氧树脂与掺合树脂之硬化反应均符合Arrhenius动力学模式，添加液化柳杉之掺合树脂达95%硬化率所需时间较环氧树脂短。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""
