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。

Deterrent effect of bitter almond oil on the adult of Sitophilus zeamais Mots. was tested. The result showed that the deterrent effect is decreased with prolonging the treatment time. On the other hand, the mortality rate of Sitophilus zeamais Mots increased in accordance with prolonging the treatment time, eventually achieve the 100% mortality.

苦杏仁精油对玉米象的忌避活性结果显示忌避活性随着处理时间的延长而降低，但是随者处理时间的增加玉米象的死亡率逐渐增大，最终达到了100%的死亡率。

In comparison with the control group, the time to falling asleep and the duration of sleep due to supraliminal dosage of sodium pentobarbital were shortened and prolonged significantly, respectively,in the small-dosage and large-dosage groups.

橙皮水提取物小剂量给药组，大剂量给药组能显著加速阈上剂量戊巴比妥钠的入睡时间和延长戊巴比妥钠的睡眠时间，差异有显著性意义。

The experiment results indicated that the cross-linking mechanism of hydrogenated terpinene maleic anhydride with bisphenol A epoxy resin was similar to anhydride curing with epoxy resin in the presence of accelerants. The curing degree was increasing as the curing temperature was arisen and the curing time was delayed, and the gelation time was shortened obviously as the curing temperature was arisen and the dosage of accelerants was increased.

实验结果表明：HTMA与环氧树脂的固化反应过程与促进剂作用下的酸酐固化环氧树脂的交联反应机理一致；固化度随温度升高、时间延长而提高，而凝胶时间随温度升高、促进剂用量的增加明显缩短。

Finally, the pH value, lactic acid, water soluble carbohydrate, ammonia nitrogen and cellulose contents were determined for WH silage prepared under the suitable adding doses of lactobacillus and cellulase at day 1, 3, 5, 15, 25, 35 after ensilaging. The pH value decreased from 5.5 before ensiling to 4.3 on the 35th ensiling day, whereas the reverse change tendence was observed for lactic acid content. The cellulose content of silage was lower from 26.5%DM in raw material to 22.3%DM.

结果表明：pH值由青贮前的5.5至青贮第35天时降至稳定的状态，而乳酸含量的变化趋势相反；凤眼莲茎叶纤维素含量从未青贮前的26.5%干物质，至青贮第35天降至22.3%干物质，降低了约4个百分点；青贮料中可溶性碳水化合物的含量随青贮时间的延长而逐渐下降，但是在第5天到第15天的时间段里，可溶性碳水化合物的含量无显著性下降；氨态氮占总氮的比例从青贮第1天的4.61%显著上升至第5天的8.25%，而从第5天开始到第35天，氨态氮占总氮的比例上升的幅度较小。

Evaluation time for the expression is important, because it lengthens the query execution time.

运算式的求值时间很重要，因为它可能会延长查询的执行时间。

He'll get much longer sessions and the work will become more interesting every day - longer outruns and more challenging problems to overcome.

训练课的时间大大延长，而且工作的内容每天都变得更加有趣--跑步时间长了，需要解决的问题更难了。

Pseudo-boehmite was prepared with nitric acid and sodium aluminate under the same precipitation conditions but different ageing and washing conditions. The influences of ageing temperature, ageing time and ageing media were studied. It was shown that pronging the ageing time and increasing temperature lead to improve crystallinity of PB., the pore diameter of PB can be increased after NH4HCO3 is added in the ageing medium.

在相同成胶条件下利用铝酸钠溶液和硝酸制备拟薄水铝石，而在不同条件下进行老化，研究了老化温度、老化时间及老化介质的影响，结果表明延长老化时间、提高老化温度和老化pH值有助于结晶度的提高，使用NH4HCO3等具有扩孔作用的溶液作为老化介质会降低产品的堆密度和增加孔径、孔容、比表面积。

Deep sleep is essential as it is the time when the body rejuvenates cells and repairs damage suffered during the day.

研究结果表明，睡前使用手机会使进入深度睡眠的时间延长，而且深度睡眠的时间会缩短。

Results showed that, with cadmium concentration and stress time increasing, the chlorophyll content in the leaves of the three fruit tree species declined, and the decreasing range was in the order of apricot, plum, and pear from high to low; relative conductivity of the leaves showed an increasing tendency; MDA content first decreased and then increased; POD activity first increased and then decreased; proline content also exhibited an increasing tendency.

结果表明：3个树种随着重金属质量分数和胁迫时间的增加，各树种叶片的叶绿素质量分数降低，其中杏树的降幅最大，李树居中，梨树最小；相对电导率有逐渐升高的趋势；叶片MDA质量摩尔浓度均出现先降低后升高的趋势；POD活性随土壤中镉质量分数的增加先升高后降低；脯氨酸质量分数随着重金属胁迫时间的延长有不断积累的趋势。
