The reduce of esters,the increase of acids,and the imbalance of the ratio of esters and acids are the main reasons for washy liquor taste and unpleasant liquor flavor after a period of storage.

酯类物质减少，酸类物质增加，酸酯比例失衡，是低度白酒贮存后口味淡薄、出现不愉快气味的主要原因。

The result indicated that the phenolic acid and its mixture could defer the remarkable time of wild oat seed germination, reduce seed germination rate, inhibit the physiological parameter and accumulated amount of dry matter to a certain extent, decrease the Root activity and chlorophyll content inordinately, and increase malondialdehyde level in seedling.

结果表明：酚酸类物质及其混合物可以显著延缓野燕麦种子发芽所需要的时间，降低最终的萌发率，对野燕麦幼苗的生理指标及干物质积累有一定的抑制作用，根系活力与叶绿素含量也有不同程度的下降，同时使幼苗体内丙二醛的含量显著增加。

The enzyme tannase, which is used in the present invention, is known to hydrolyse the galloyl ester linkages of polyphenolic substrate s such as tannic acid, tea polyphenol gallates, and the like.

我们知道，这种在本发明中所使用的丹宁酶，可水解多酚酸类物质的棓酸酯键，如丹宁酸，茶叶的棓酸多酚酯及其类似物。

The results revealed that with the increasing ear of continuous C. sativus cropping soil vanillic acid, p-hydroxyhenzoic acid and ferulic acid accumulated gradually. The total amount of the three phenolic compounds reached 29. 8 mgkg^(-1) dry soil after 7 years cropping, being markedly higher than that after 1 or 3 years cropping. After treated with these compounds, the root length and stem width of C.

结果表明：土壤中香草酸、对羟基苯甲酸及阿魏酸随黄瓜连作年限增加而呈现积累趋势；在连作7年的大棚土壤中3种酚酸类物质总量达29.8mgkg^(-1)干土，显著高于连作1年和1年土壤中的含量；酚酸物质可使黄瓜幼苗根长及茎粗显著降低，使株高及干物质量略有下降。

By using the "mechanical wounding"experimental system estabilished by us, and light- and electron microscopy, autoradiography and radioisotope technique, immuno-fluorescence localization, homologous clone and RACE technique, in situ mRNA hybridization and ELISA et al., we investigated the relationship between the transportation of exogenous JA and the secondary laticifer differentiation, the relationship between the producton and accumulation of endogenous JA and the laticifer differentiation from cambia, and the effect of appling exogenous jasmonates on the natural rubber production.

利用我们建立的机械伤害诱导乳管分化的实验系统，采用光学显微镜和电子显微镜技术、同位素示踪和放射自显影技术、免疫荧光定位技术、同源克隆和RACE技术、mRNA原位杂交和ELISA等技术，研究了外源茉莉酸在橡胶树体内的移动及其对维管形成层分化次生乳管的诱导效应、内源茉莉酸与乳管分化的关系以及茉莉酸类物质对天然橡胶产量的影响。

The enzyme tannase, which is used in the present invention, is known to hydrolyse the galloyl ester linkages of polyphenolic substrates such as tannic acid, tea polyphenol gallates, and the like.

我们知道，这种在本发明中所使用的丹宁酶，可水解多酚酸类物质的棓酸酯键，如丹宁酸，茶叶的棓酸多酚酯及其类似物。

For ozonolysis, the SOA yield has not been changed by inorganic seed aerosol, because the products are mainly carboxylic acids, which has much lower saturation vapor pressure and thus easily undergo homogeneous nucleation or gas-particle partitioning to be in the aerosol phase.

而对于α-蒎烯臭氧氧化的过程，实验结果表明，干态硫酸铵颗粒物种子的存在对SOA产率无影响，对臭氧氧化生成的SOA分子鉴别的结果表明，可鉴别组分中有很高比例的有机羧酸类物质，这一比例远高于光氧化产物，这些有机酸具有较低的挥发性而极易形成颗粒相，并且不参与异相酸催化反应。
