In mathematics , a division is called a division by zero if the divisor is zero . Such a division can be formally expressed as a /0 where a is the dividend. Whether this expression can be assigned a well-defined value depends upon the mathematical setting. In ordinary arithmetic, the expression has no meaning .

如果某一上市公司宣布派发红利股份、红利认股权证、以折让价供股或派发其它有价权益，在除权日之前一日持有它的股票的人士可享有该等权益，在除权日当日或以后才买入该公司股票的人则不能享有该等权益。

The expression sequence is then evaluated by code in the AXParser class to produce an Expression object that represents the input algebraic expression by means of a tree of Expression objects.

表达序列然后评估在AXParser类中的代码产生一个表达的对象，表示输入了一个对象树的表达方式代数式。

In addition, using RT-PCR to detect expression of centrin homogene during Urechis unicinctus spermatid deferentiation and early embryonic development. The result revealed that (1) expression of HsCEN1 homogene is present during spermatid defferentiation including spermtid and sperm, but not in adult tissues including body wall tissue,intestinal mucous memberane cells and cell in coelom succus;(2) expression of HsCEN1 homogene is not present in unfertilized oocytes but present in that of released polar bodies after fertilization and parthenogenesis oocytes treated with A23187;(3) expression of HsCEN1 homogene is present during early embryonic development including two-cell stage,multicell stage,gastrula to trochophora.

我们还用RT-PCR方法检测了Centrin同源基因在单环刺螠精子分化过程和早期胚胎发育过程的表达，结果显示：在单环刺螠精子发生过程中的精细胞、精子团、精子中都有表达，而在成体的体壁组织、消化道组织、体腔球中则没有表达；在未受精卵中没有表达，而在受精后释放极体的受精卵和经A23187孤雌激活的卵中则有表达；在单环刺螠的早期发育过程——二细胞胚胎、多细胞胚胎、原肠胚、早期担轮幼虫——中都有表达。

From the calculation of two different similarity measures—Pearson correlation coefficient and Spearman correlation coefficient, we found that about 94 percent of gene expression regulatory pathways are correlatively expressed in more than 4(including 4) sets of expression profile data, and it presents additional evidence for the correlation between gene function and its expression in the view of gene expression regulatory pathways.

通过Pearson相关系数和Spearman相关系数两种相似性测度的分析，我们发现有94%（15条）的基因表达调控通路内的基因在大于等于4套的表达谱数据中是共表达的，以上结果从基因表达调控通路的角度，证实了基因功能与基因表达之间存在着一定的相关性。

Thus, our results indicated that the expression of Dicer could be inhibited by anti-Dicer shRNA expression vectors, and that the expression silencing activity of shRNA expression vectors is dependent on the presence of Dicer enzyme.

结果表明，抗Dicer基因shRNA表达载体，能够明显抑制Dicer基因的表达；shRNA表达载体的功能发挥需要Dicer酶的直接参与。

The expression level of tim gene in 25LL is markedless higher than 15DD and 20LD in the early incubation stage(7 days before), but it is obviously higher than 20LD and 15DD conditions in the late.To further invesgate the per and tim expression in different moment every day of the sensitive period(7d,8d,9d) during the process of embryogeny,the expression of tim gene was very low and the per and tim expression did not have obvious rhythmicity under 15DD condition.

进一步调查家蚕胚胎对环境敏感时期(7d-9d)per和tim基因的昼夜表达节律，在15DD条件下，tim基因表达量一直很低，tim基因和per基因的表达量都没有明显的节律性变化；而25LL和20LD条件下，两基因在一日中不同时刻的表达具有明显的节律性，表达量也较高。

When this condition occurs, inbound replication with the source partner is stopped on the destination domain controller and event ID 2042 is logged in the Directory Services event log.
