Chicks reared under natural light are frequently debeaked at 1 day of age or a few days after delivery to the brooder .

在天然光线下饲养的小鸡，经常是在一日龄时或在进入育雏室后几天内断喙。

The result showed that the scion with different bud age, grafting seedlings with different growing condition, lignification degree in grafting part of rootstock, and the scion in different seasons were substantially influent to the grafting survival rate.

结果表明，不同芽龄的接穗、嫁接苗不同的生长条件、砧木嫁接部位木质化程度以及不同季节的接穗对嫁接成活率都有较大的影响。

CDNA fragment of cadherin-like protein gene in the fifth instar larva of oriental tobacco budworm was amplified using degeneracy primers and RT-PCR technique, and the target fragment was further sequenced after being cloned into pMD18-T vector plasmid.

本研究以烟夜蛾五龄幼虫中肠的总RNA为模板，根据已经克隆的其他昆虫的类钙粘蛋白基因序列设计引物，利用RT-PCR技术扩增出了烟夜蛾类钙粘蛋白基因的cDNA片段，将其连接到pMD18-T载体，转化大肠杆菌后筛选阳性克隆并进行序列测定，测序得到的1335bP的片断编码444个氨基酸残基。

Insect resistance to Bt toxin is related with the variation of cadherin-like protein gene.cDNA fragment of cadherin-like protein gene in the fifth instar larva of oriental tobacco budworm was amplified using degeneracy primers and RT-PCR technique,and the target fragment was further sequenced after being cloned into pMD18-T vector plasmid.

It should be noted that some Burgundian producers tend to over-fill their bottles during the bottling process which may cause a few drops of wine to become trapped netween the capsule and the cork.This should not be confused with ullage,a natural occurrence in older wines,which may be accelerated due to poor provenance.

大家可以留意到很多勃艮第酒厂都会入瓶时将酒斟得很满，以致有数滴的酒堵于盖囊和木塞之间，不过，请不要误会了酒龄越高的酒亦有水位上的差异，那是因为贮藏得不好的正常现象。

Scan sampling and Focal sampling methods were utilized to determine the behavior mode, daily rhythm and behavior trends of the nestlings of Great Bustard;Each growth indicator were measured to obtain the growing curves and equations;Correlation analysis was taken between the behavior and growth indicators of young Great Bustard to understand the relation between them.

本实验采用扫描取样法和目标取样法相结合观察大鸨雏鸟的行为模式，研究了大鸨雏鸟行为日节律及其行为随日龄增长的强度变化趋势；定期对大鸨雏鸟各生长指标进行测量，总结大鸨雏鸟的生长发育规律，拟合生长曲线和方程；对大鸨雏鸟的行为和生长发育指标进行相关性分析，确定生长指标与行为变化规律之间的关系。

Dr. Caan noted that age-related changes in body composition, metabolic factors and hormone levels, combined with declines in physical activity, are all factors that can contribute to weight gain and obesity as women age.

Caan博士称，身体成分、代谢因素和激素水平的随龄变化，加之身体活动的减少，都是有助于妇女体重增加和肥胖的因素。

The difference between Taijiquan group and the adult control group is not significant.Conclusion:persistent Taijiquan exercise might be beneficial for preventing the loss of bone mass of calcaneum and reducing the risk of male hormone decrease in aged males with aging.

由此得出长期坚持太极拳锻练对保持和延缓老年男性跟骨骨量有积极作用，并能有效地延缓老年男性随龄增加的雄激素的下降趋势。

When insoluble collagens were heated in the buffer solution of pH 7.5 at 60℃,both the collagens of 4－months old pigskin and calfskin were 60% solubilized in 1h and 90% in 22h while both the collagens of 1－years old pigskin and cow hide were 30%~40% solubilized which less than former two.

由于动物的年龄不同，胶原的性质变化显著，不溶性胶原在pH7.5、60℃水中加热时，4个月龄猪皮和幼牛皮在1h可溶化60%，22h可溶化90%，但1年龄猪皮和成牛皮可溶化率减少30%~40%。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
