数

Customer: not necessary for me. my hair is countable.

先生道："不必，我的头发数都能数出来。"

However, these methods are estimated according to sample variance and covariance estimators of returns.

然而，这些方法都是根据样本的变异数或报酬的共变异数估算的估计值。

The inconsistencies of dimensional reduction and naive dimensional regularization in dealing withChern-Simons-matter theory are analyzed.The consistent dimensional regularization combiningwith higher covariant derivative regularization is adopted to consider Chern-Simons field theorycoupled to complex scalar and spinor field.All the local parts of one-loop two-point functionsand three-point functions are computed.Slavnov-Taylor identity is combined with these explicitcalculation results to give the one-loop local effective action.The finite gauge invariant quantumcorrection is shown and finite wave function renormalization constant for each field is defined.Thelocal part of one-loop three gauge field vertex is especially evaluated and it is verified that thereexists a renormalization choice compatible with BRST symmetry.

然后计算了所有的两点函数和三点函数单圈修正的定域部分，利用S-T恒等式给出了单圈定域有效作用量，定义了场的重正化常数，发现物质场和规范场都存在有限的规范不变的量子修正，并讨论了这些有限的规范不变的量子修正的物理意义，进而通过考察单圈三规范场顶角，表明存在与BRST对称性相容的重正化选择。5、在背景场方法的框架下，选择高阶协变导数正规化与维数正规化的杂化正规化方案计算了背景场两点函数的两圈量子修正，结果表明，标志紫外发散的极点项恰好抵消；进一步利用背景场方法中明显的规范对称性，证明背景场三点函数的两圈图贡献也是有限的。

Yet cooperation will be critical for the region to meet its water challenges in the years and decades ahead.

然而，合作却是该地区在未来数年甚至是数十年内应对水资源挑战的关键所在。

objectiveto discuss the anti-tumor effect of 20-ginsenoside rh2 on skin tumor-bearing mice, induced by dmba/croton oil.

方法在脱去毛发的昆明鼠背部涂抹dmba丙酮液以及巴豆油丙酮液，观察动物背部乳头状瘤发生情况，记录荷瘤小鼠数及各鼠荷瘤数。

MethodsSmear 0.25% croton oil＼acetone ag on the back of kunming mice,and observe the growth condition of papilloma,then record the quantity of tumor-bearing mice and the quantity of tumor in each mice.

Methodssmear 0.25% croton oil＼acetone ag on the back of kunming mice,and observe the growth condition of papilloma,then record the quantity of tumor-bearing mice and the quantity of tumor in each mice.results20-ginsenoside rh2 prolonged the incubation of tumor, reduced the quantity of tumor-bearing mice and decreased the amount of tumor in each mice.conclusion20ginsenoside rh2 has obvious anti-papilloma effect on the mice skin.

结果20-人参皂苷rh2对小鼠皮肤乳头状瘤有明显的抑制作用，可使肿瘤发生潜伏期延长，使化学致癌物诱发的荷瘤动物数明显减少，每鼠荷瘤数显著下降。结论20r 人参皂苷rh2在预防癌症的发生和发展方面有重要的作用，也是很有前景的新型抗癌药。

After therapy copies of Cryptococcus neoformans CAP10 gene decreased significantly in the group of improvement.

好转组CAP10mRNA拷贝数治疗前、后CAP10 mRNA拷贝数(log10值)分别为1.28、0.75(n=20，P.05)，有显著性差异。

Most people have spent months or years taking care of their hair and a cheap curling iron can damage all that hard work.

大部分人都花了数月或数年照顾自己的头发和廉价冰壶铁可以破坏一切的辛勤工作。

Then, after introducing the direct current sensitivity analysis method of general ATC, the direct current sensitivity analysis method of blind number ATC is studied, and some predigestion tips are also proposed to decrease computational effort.

以确定性可用输电能力的直流灵敏度分析法为基础，提出盲数ATC的直流灵敏度算法，并给出盲数运算的简化处理方法。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
