The catabolites of acetoin metabolism such as 2,3-butanediol and acetaldehyde as well as other carbohydrates including galactose, lactose, and glycerol did not affect the expression of Paco and PacoK, whereas maltose stimulates the expression of PacoK at 210 min.

其他的乙醯甲基甲醇代谢物如2， 3-丁二醇与乙醛，以及其他糖类包括半乳糖，乳糖和甘油对acoABCD及acoK启动区的表现能力并无明显影响，而在210分钟时，麦芽糖则可刺激acoK启动区的表现。

According to experiment processes and SEM photographs of the best polymer, pure polyacrylates emulsiods were destroyed during preparation and lumps caused by self-cohesive action were formed and difficult to break up, which the co-polymers emulsiods from partially neutralized acrylic acid and acryl amide forming into unconsolidated bulkload were undivided.

通过SEM照片我们发现，纯的聚丙烯酸盐高吸水性树脂乳胶粒在沉淀洗涤的过程中由于自粘结作用大部分被破坏了，形成难以破坏的块状物，而部分中和的丙烯酸-丙烯酰胺共聚物高吸水性树脂的乳胶粒完整无缺，形成较为松散的粒状物。

This result might indicate that the apteral tea aphids may use tea shoot volatiles as kairomone to find their optimal feeding sites,i.e. fresh tender tea shoots.

研究显示无翅茶蚜可能利用茶梢挥发物作为利它素而寻觅适宜的取食场所，如茶树嫩梢。

In the presence of ethanol- HCl solution, arylamine-HCl and w=37% aqueous formaldehyde solution or the condensation product of arylamine and formaldehyde are directly reacted with ethyl 3-oxo-2-phenylmethylenebutyrate to form l-aryl-2-phenyl-3-carbethoxy-4-piperidone.

2－苯亚甲基－3－丁酮酸乙酯与芳香胺和w＝37％甲醛水溶液或芳胺和甲醛的缩合物在氯化氢－无水乙醇存在下可直接发生的Mannich反应，得到1－对位取代芳基－2－苯基－3－羰乙氧基－哌啶－4－酮。

Results of DSC determinations show that an adequate content of atactic polystyrene is favourable of the crystallization of isotactic polystyrene,but the addition of more aPS linearly decreases the crystallinity of iPS because of the dilution effect.

DSC测定表明，产物中的无规物有利于等规聚苯乙烯结晶，但对结晶的熔点有降低作用。向产物加入更多的aPS则由于稀释效应而使iPS的结晶度线性下降。

It is to say that after amplificated a few autogenetic cells in vitro,we can make cell-scaffold complex when mix these cells with scaffold which has cytocompatibility and biodegradability.

同时，这种细胞—支架复合物无免疫原性，且拥有和自体组织类似的结构和功能，因此被认为具有广泛的应用前景。

And if thy oblation be a meat offering baken in a pan, it shall be of fine flour unleavened, mingled with oil.

2：5 若用铁鏊上作的物为素祭，就要用调油的无酵细面

In time past, strong of foot, I walked gaily up the noble hill that leads to Beachy Head fromEastbourne, joying greatly in the sun and the wind.

每一步都要踩碎不少细小的灰色的贝壳，壳已风干，内中空无一物，在脚下咭嘎地响犹如白霜或易碎的珠子。

Methods The primer design is referring to thearticleof Bulter. Over 120 samples provided by the laboratoryare detected to verify the concordant results between miniSTR andcommon STR. We construct the miniSTR multiplex system usingdomestic Taq DNA polymerase, and detect the results by ABI—310Genetic Analyzer. We have alsostudied the sensitivity, accuracy, species-specificity and different PCR outcome under each annealtemperature.

方法参照Bulter等对THO1、TPOX、CSF1PO三个基因座miniSTR的引物设计，选用本教研室提供的123例无血缘关系个体的血样，进行THO1、TPOX、CSF1PO三个基因座PCR-miniSTR银染检测，检测结果与商品化试剂盒的检测结果进行一致性检验；采用国产DNA聚合酶构建miniSTR荧光标记复合扩增体系，用美国ABI-310基因分析仪进行检测；对该荧光标记复合扩增体系的灵敏度、准确性、种属特异性、不同退火温度下复合扩增的效果、陈旧血痕DNA的检测等进行研究。

The contents of caecum and rectum of 30 healthy broilers were collected by aseptic method.

无菌采取30只健康鸡的盲肠、直肠内容物，以大肠杆菌O_8为宿主，从这些样品中分离到一株能裂解其它细菌的细菌。
