龄

The nature of aging is relationship between Arrears and sales, through the aging analysis of accounts receivable can provide a basis for policy formulation.

账龄的本质是欠款额与销售额之间的关系，通过账龄分析，可以为应收账款政策的制定提供依据。

Aging accounts receivable means classifying each receivable according to its age.

对应收账款作账龄分析意味着根据每笔应收款的账龄进行分类。

The aging of accounts receivable, however, provides a more reliable estimate of uncollectible accounts because of the consideration given to the age and collectibility of specific accounts receivable at the balance sheet date.

但应收账款的账龄分析提供了对坏账的更为可靠的预估，因为它考虑了在资产负债表日各应收账款的账龄和可回收性。

Establish accounts receivable aging schedule, according to customer credit period, monthly customer accounts receivable reconciliation schedules, and sales staff reconciliation, making timely loan recovery, establishing control of payables aging Table, according to the suppliers credit for a timely manner to cope with the changes this month and beyond the purchase price to be paid for the goods.

建立应收账款账龄明细表，按客户不同信用期，每月编制客户的应收账款对账明细表，与销售人员进行对账，使得货款及时收回；建立应付账款的账龄控制表，根据供应商的信用期限，及时变更本月应付的货款和以后将要支付的货款。

For improving the air quality, the concepts of age of air are introduced and the solutions of age of air and ventilation efficiency are obtained by using tracer gas concentration of typical points of the cabin.

为了提高客舱内空气品质，引入了空气龄的概念并给出了由客舱内典型点的示踪气体的浓度求空气龄及通风效率的方法。

Therefore, based on documents reports, through contrastive observation of 20-month-old natural senile mice, this study has confirmed that the anaplasia of subacute senile model mice was obviously similar to the features of 20-month-old naturally physiological senile mice. Mice in both two groups displayed dull color patterns, slow movements, insensitive responses and decrease of growth rates of body weight; hepatic and brain tissues in the mice presented senile features of sero-enzyme such as decrease in SOD activity, increase in content of lipid perhydrides and so on.

为此，本研究在文献报道基础上，通过与20月龄自然老化鼠的对比观察，证实：亚急性衰老模型鼠的退行性变化与20月龄自然生理性老化鼠特征的相近之处鲜明可见。2组均出现毛色暗淡，少有光泽，动作迟缓，反应不灵敏，体重增长率下降；肝、脑组织出现SOD活力下降，脂质过氧化物含量增高等血清酶学的老化特征。

METHODS摘要: Molecular cloning techniques were used to construct the recombinant plasmid pLMP1p53mt containing mutant p53 gene and EB virus LMP1 gene. Linear recombinant plasmid pLMP1p53mt was transfected into mouse androgenesis of germ cells by microinjection and then survival germ cells treated were planted into fallopian tubes of artificial pregnant female mice.

方法摘要：通过分子克隆技术构建含突变型p53基因和EB病毒LMP1基因的真核表达载体pLMP1p53mt；采用显微注射法将线性化的表达载体注射至小鼠受精卵的雄性原核中，然后将注射存活的受精卵植入假孕母鼠的输卵管；取其产3 wk龄子代鼠进行PCR初选，再通过Southern杂交进一步确证；利用HE染色法观察4 mo龄转基因小鼠不同组织病理变化。

Common names include trillium , wakerobin , Tri Flower , and birthroot .

通用名称包括延龄，wakerobin，三花，和延龄草。

The result showed that the single correlation between the characters of weight and heart girth, chest width and circumference of cannon bone was significantly different. The correlation between weight and heart girth, chest width, circumference of cannon bone was highly positive correlation. Among seven regression models, the correlation index of six regression models was over 0.7, but that of 60 days was 0.452. The result suggested that selecting body weight was efficient through heart girth, body high, chest width and circumference of cannon bone.

对不同日龄各项体尺与体重建立的了回归方程，结果表明，60日龄回归模型的决定系数R~2=0.452，其它6个回归模型的相关指数均在0.7以上，其中方程1、5、6、7的相关指数都在0.9以上，表明这些回归方程中各项体尺指标与体重之间相关密切，根据胸围、管围、体高和胸宽对体重的选择都是有效的，具有一定的参考作用。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
