But urushiol has a poor resistance to alkali because phenol hydroxyl of urushiol shows weak acidity. Meanwhile, inherent brittleness of urushiol has limited its development and application.

但是，由于漆酚的酚羟基显弱酸性，使得漆酚耐碱性较差；同时，漆酚清漆固有的脆性等也限制了其发展和应用。

The structures and configurations of other components weredetermined too.The results show that the structure of components ofChinese lacquer urushiol are the same as components of Japaneselacquer. In this work,2D-heteronuclear relayed coherence transferspectroscopy plays an important role in determining molecularskeleton carbon linkage.

研究结果表明，中国生漆漆酚中含量最大并起关键作用的两双键共轭的三烯漆酚的结构与构型与日本漆中的该组分完全相同，即都有末端甲基的3—十五碳烯烃（8′Z，11′E，13′Z）邻苯二酚，而没有末端双键的存在，其它几个漆酚主要组分的结构也与日本漆酚对应组分基本相同。

It was found that the alkoxy of the aluminium alkoxide can be exchanged to the arkoxy of the raw material or product in the process of reaction. The alcohol producing in the exchange reaction reduces the yield of furan phenol by the further by-reaction of the alcohol with the raw material or product.

结果表明，醇铝在催化单醚合成呋喃酚过程中，醇铝中的烷氧基与原料单醚和产物呋喃酚的芳氧基发生了交换，交换生成的醇与单醚或呋喃酚发生副反应降低了呋喃酚收率。

Solid mixtures comprising a variety of high melting bisphenols; 4,4'-biphenol; 3,3,3,3'tetramethylspirobiindanbisphenol, and 4,4'-sulfonydiphenol are converted to stable, homogeneousmelt solutions at 200 DEG C, a temperature substantially below the melting points of the high melting bisphenols in their pure states.

在200℃下，基本低于纯态高熔点双酚的熔点的温度，将含有各种高熔点双酚；4，4′-二酚；3，3，3，3′四甲基螺二茚满双酚，和4，4′-磺酰联苯酚的固体混合物转化为稳定、均质的熔体溶液。

The super acid SO〓/ZrO〓, due to its strong acidity, favores the dealkylation and disproportionatin of 4-TBC or/and DTBC, preventing the increase of the selectivity for 4-TBC.

而固体超强酸SO〓/ZrO〓由于酸性较强，易于发生4-叔丁基邻苯二酚和3，5-二叔丁基邻苯二酚的脱烷基反应和4-叔丁基邻苯二酚的歧化反应，因此不利于提高4-叔丁基邻苯二酚的产率。

The antioxidative action may involve trapping the initiating radicals generated by AAPH in the bulk water phase, trapping the initiating radicals generated by DBHN in the surface of the micelles, inhibiting the propagating lipid peroxyl radicals on the surface of micelles and regenerating α-tocopherol by reducing the α-tocopheroxyl radical.

茶多酚的抗氧化机理可能涉及到在水相中捕获链引发自由基R00·和在胶束表面捕获链引发自由基t-BuO以及在胶束表面捕获链增长自由基LOO和在胶束表面与α-生育酚自由基反应从而再生α-生育酚。

Tocopherol has very high physiological activity. Soybean deodorized sludge contains plentiful natural tocopherol. For extracting tocopherol from soybean deodorized sludge, solubility of α tocopherol in supercritical CO 2 is measured. The solubility data are correlated by RBF neural networks model and chrastil model. Relative error of chrastil model is 25.36%. By means of learning and training on RBF neural networks model, the average error of training set is 0.23% and that of testing set is 6.48%....

生育酚有很高的生理活性，油脂生产中得到的脱臭馏出物含有丰富的天然生育酚作为萃取生育酚的基础，对甲酯化油脂脱臭馏出物中α-生育酚在超临界CO2 中的溶解度进行了测试，并用Chrastil分子缔合模型和RBF神经网络模型对溶解度数据进行了拟合 Chrastil分子缔合模型的相对误差为 2 5.36%对于RBF神经网络模型，经过网络学习和训练，训练集平均误差仅为 0 。2 3%，测试集误差为 6.4 8%，效果比较理想

Results showed that hypochromism and red shifted KAE absorption spectra were observed in the presence of DNA,and that synchronous fluorescence of DNA-NR was quenched with addition of KAE,indicating that a strong competition for DNA binding ...

结果表明：加入DNA后，山柰酚的吸收光谱呈现减色和红移现象；山柰酚的加入使得DNA-NR同步荧光强度猝灭，表明山柰酚对NR与DNA的结合为竞争性抑制；山柰酚的加入使得DNA的粘度增大，热变性温度升高。

Results showed that hypochromism and red, shifted KAE absorption spectra were observed in the presence of DNA, and that synchronous、 fluorescence of DNA-NR was quenched with addition of KAE, indicating that a strong competition for DNA binding between KAE and NR existed, in addition, the relative viscosity and the value of melting temperature of DNA increased in the presence of KAE.

结果表明：加入DNA后，山柰酚的吸收光谱呈现减色和红移现象；山柰酚的加入使得DNA-NR同步荧光强度猝灭，表明山票酚对NR与DNA的结合为竞争性抑制；山柰酚的加入使得DNA的粘度增大，热变性温度升高。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
