Between 4-9L exposures, C2H4 has a desorption channel at 155-180K. C2H4 desorption at 130K maybe results from BrCH2CH2Br absorbs in Br atom toward surfaces, after C-Br bond scission, because C2H4 has no opportunity to touch surfaces so it desorbs at low temperature. C2H4 desorption at 210K is likely to be desorption limited that, BrCH2CH2Br docomposes to C2H4, only to desorb at higher temperature. This C2H4 desorption channel maybe comes from defect site desorption.

曝露量在4-9L之间，C2H4在155至180K的范围内也有脱附的管道。130K的C2H4脱附可能是因为BrCH2CH2Br分子以Br原子朝向表面的方式吸附，在断了C-Br键后，C2H4分子没有机会接触到表面在低温就脱附了。210K的C2H4可能是脱附所决定的，亦即BrCH2CH2Br分解后在表面形成C2H4，随后温度升高至较高温才从表面脱附，此C2H4管道也许是来自缺陷位置上的脱附。

In this research, large volume stainless pots, high－quality pottery pots and enamel pots, instead of traditional small volume pottery pots, were used in storing several kinds of fresh liquor like "Shuanggou Liquor" etc.and the analysis of stored liquor by gas chromatography and atomic absorption spectrum indicated that the application of large volume stainless containers, instead of the traditional pottery pots, could not only advance liquor aging , produce flavour and remove precipitate, develop soft liquor style, stabilize and improve liquor quality,harmonize the balance of components , decrease liquor loss and liquor storage space,but also promote oxidation , reduction, esterification and molecular hydrogen bond association in the process of liquor storage.

对&双沟酒&等各香型酒，利用大容器的不锈钢罐、优质陶缸和搪瓷罐代替传统小容积陶坛或陶缸贮存新酒作了试验研究。采用气相色谱和原子吸收光谱对贮酒分析，得出采用不锈钢等大容器代替传统小陶罐贮存酒，不但可使酒在贮存过程中进行氧化、还原、酯化和分子氢键缔合作用，促进酒体老熟去杂增香，使酒体柔和老熟、成分平衡协调，稳定和提高酒质；而且还可以降低酒的损耗和减少贮酒库占地面积。孙悟

The result indicated that MgO and α- methacrylic acid can together thicken epoxy, and the speed of thickening epoxy become quickly with the increasing content of MgO; when the ratio of MgO and α- methacrylic acid is 3:1, thickening epoxy have a better effect; the thickening mechanism: the terminal corboxyl group of α- methacrylic acid react with MgO, and it accompany with large numbers of heat, the heat can accelerate the reaction between the terminal corboxyl group with the secondary hydroxyl groups of epoxy, intermolecular hydrogen bonding which the water of above-mentioned formation result in and complex compound which format the metal atoms and carbonyl group complexing collective increase the viscosity of epoxy resin.

结果表明：MgO和α－甲基丙烯酸配合可增稠环氧树脂，随着MgO加入量的增加，环氧树脂增稠的速度加快；MgO与α－甲基丙烯酸为3：1时，增稠环氧树脂的效果较好；推测环氧树脂的增稠机理是α－甲基丙烯酸中的端羧基与氧化镁反应，放出热量促使其端羧基与环氧树脂中的仲羟基反应，上述反应生成水产生的氢键和羰基与氧化镁中的金属原子形成络合物共同导致环氧树脂的粘度增加。
