结果表明，无分散剂时，随着乙醇中水的体积分数的增加，乙醇汽油的分层温度逐渐升高；加入主分散剂可以显著降低乙醇汽油的分层温度，而少量助剂B、C可显著改善主分散剂A1的助溶效果；随着分散剂体积分数的增加，乙醇汽油的分层温度逐渐降低；在乙醇体积分数为10%，乙醇中水的体积分数为4.3%，分散剂的体积分数为2.91%，其组成V(A1)∶V∶V为90∶7.5∶2.5时，乙醇汽油的分层温度可达到-25℃。90号汽油的辛烷值调合后提高到93号，且其T10和T50点均较调合前低。

The analysis of the components and contents of volatile material indicated that fruit of apples treated with 2 and 4ml/kg of ethanol increased the content and kinds of the characteristic volatile and improved flavor and quality in apple, while the fruit treated with 6ml/kg of ethanol produced higher contents of volatile material and developed off-flavor. Fruit of'Yar'pear treated with 2 and 4ml/kg of ethanol increased the sweet taste and aroma, but higher ethanol concentration showed off-flavor.

对苹果挥发性物质成分的分析表明，2及4ml/kg的乙醇处理增加了苹果特征风味挥发性物质的组分及含量，使水果呈现果香和花香，改善了苹果的品质，而6ml/kg的乙醇处理也能增加苹果果香，但由于强烈果香味的乙酸乙酯等组分在所增加的挥发性物质中所占比例较大，果实呈现浓烈的果香，并使果实的在口中的余味较差，在感官评价中稍差。2和4ml/kg的乙醇处理增加鸭梨甜味，并具有清爽的果香味，而高剂量的乙醇处理余味较差。4ml/kg乙醇处理，在挥发性物质组分数量上与对照差异不大，但却使乙醇形成酯类增加，使鸭梨果实呈现浓郁的果香。

The article reviewed the following points: the distribution in corpse, and how to sample, the influences on the diffusion of alcohol and putrefaction, the discussion about alcohol mass concentration measure methods.

本文对乙醇在体内的分布特点、如何合理取材及死后乙醇扩散、尸体腐败产生的乙醇对乙醇质量浓度分析的影响进行了综述，并对死后乙醇质量浓度检测的分析评价策略进行了讨论。

The results showed that ascorbic acid oxidase activity in the flesh of 'brumal Jujube' became significantly higher than in pericarp with the development of maturity; but these activities of peroxidase , Polyphenoloxidase and phenylalanine ammonia-lyase in flesh were lower than in pericarp . During the development from green to half-red then to red, the lignin and fibre contents in pericarp gradually increased higher than in flesh; ethanol content also increased , acetaldehyde content reached to a peak during the red maturity stage and then declined.

随着贮期的延长，冬枣果肉中乙醇和乙醛含量增加，乙醇发酵关键酶的活性逐渐升高；气调贮藏延缓了果实中乙醇和乙醛的积累，抑制了PDC和ADH的活性，显著提高了果实的贮藏品质；说明气调贮藏延缓了果实的乙醇积累；但CA_1比CA_2促进果实乙醇积累的作用较明显，表明冬枣对高浓度CO_2较敏感，这可能是枣果实不耐高CO_2的原因之一。

Through comparison of energy inputs in corn fuel ethanol life cycle,fossil energy inputs of corn production and ethanol conversion processes were identified as the most important,and therefore nitrogen fertilizer,electivity and diesel used in corn farming and energy consumption of distillation and dehydration process in ethanol production could be known as the most influential factors for the energy benefit of corn fuel ethanol.

但是玉米燃料乙醇从原料的生产、乙醇的转化，一直到被燃耗的整个生命周期中的多个阶段需要直接或间接地消耗矿物能源，因而，虽然玉米燃料乙醇是可再生能源，然而是否具有可持续性及可持续性的大小则取决于其燃耗中所产生的能量与燃料乙醇整个生命周期中所消耗的能量相比是否有盈余及盈余的大小。20世纪70年代中期，玉米燃料乙醇的能量平衡问题研究首次在美国出现[2，3]，当时乙醇替代汽油的能量效益的有关研究指

This experiment aimed to systematically investigate and analyze the ethanol activated rates of mouse oocytes, affected factors of oocytes activation, types and development of parthenotes, and the organization and roles of the cytoskeleton during pronuclear formation and migration and early embryo cleavage by ethanol activation of oocytes, embryo culture in vitro and immunofluorescence cyto-chemistry. The results:(1) The ethanol activation of mouse oocytes showed that the activated and developmental rates of oocytes increased significantly with the increase of ethanol concentration and extension of exposure time, but over concentration and exposure time would result in increased fragment rates significantly. 7% ethanol treated oocytes for 7min was the optimum activated condition.

本实验主要利用卵母细胞的乙醇激活、胚胎体外培养和免疫荧光细胞化学方法对小鼠卵母细胞乙醇激活效率、影响因素、孤雌胚类型、发育、原核形成、迁移及早期胚胎卵裂过程中细胞骨架的组装、作用等进行了系统的研究和分析，结果显示：(1)小鼠卵母细胞的乙醇激活结果表明，随着乙醇浓度的升高和作用时间的延长，卵母细胞激活率和发育率都显著提高，但乙醇浓度过高和作用时间过长会导致卵母细胞碎裂率的显著增加，7%乙醇作用卵母细胞7min 为最佳激活条件。

The ethanol content in fruit flesh of'Starking'apple, 'Yar'pear and'Shingo'pear increased in early storage with ethanol-applied concentration increased and decreased later. At the end of the storage for 5-6months, there was no difference in ethanol concentration in fruit flesh in all treated apple or'Yar'pear treated with 2 and 4ml/kg fruit of ethanol and control, but that in 6ml/kg fruit of ethanol treated'Yar' pear was higher than that in control.

红星苹果、鸭梨和新高梨经乙醇处理后，果肉中乙醇含量呈先升后降趋势，果实内积累乙醇浓度与乙醇处理浓度显著正相关。2、4、6ml/kg乙醇处理的红星苹果在贮藏5、6个月后，果实中的乙醇含量与对照无差异；2和4ml/kg乙醇处理的鸭梨在贮藏5、6个月后果肉中的乙醇含量与对照无显著性差异，但6ml/kg的乙醇处理果实中的乙醇含量却显著高于对照；相同的乙醇处理浓度使新高梨果实中积累更高的乙醇含量。
