计数

This paper aims to find the test formulas for the marginal distribution in 2×2 table and Comparis on of the differences between the marginal probabilities with two 2×2 tables methods.

在科学研究中，广泛采用重复测量或配对设计的方法进行研究，而在许多情况下其测量或观察资料为 2分类计数资料。

So, the nucleocytoplasmic ratio decreased. 10^(-5)MATRA significantly suppressed the proliferation of os732 with only 39.5% cells when compared with untreated cells. Cells in G1 phase increased significantly, and the number of S phase decreased. Expressions of cy-clinD1, cycimD2 and CDK4 mRNA declined, especially cyclinD2 and CDK However, expressions of cyclinD3 and P21WAF1 mRNA changed little.

结果 ATRA作用后，OS732细胞胞浆展开，细胞核变小，核浆比例变小；瘤细胞生长减慢，细胞计数为正常对照组的39.5%； G0/G1期细胞明显增多，S期细胞减少，细胞阻滞于G0/G1期；CyclinD1、CyclinD2、CDK4mRNA表达均下降，尤以CylinD2、CDK4下降最明显，CyclinD3、P21WAF1mRNA未见明显改变。

Methods OS732 was treated with 10^(-5)MATRA for 6 days, then we observed cell morphology, counted cell number, analyzed cell cycles by flow cytometry and detected mRNA expressions of cyclinD (Dl, D2, D3), CDK4, P21 by semi-quantity RT-PCR. Treatmed with 10^(-5)MATRA, The nucleus of OS732 cells became small and condensed, and cytoplasms expanded.

用10^(-5)MATRA作用骨肉瘤细胞OS732， 6d后，进行细胞形态学观察、活细胞计数、流式细胞仪分析细胞周期、半定量RT-PCR检测细胞周期调控蛋白CyclinD(D1、D2、D3)、CDK4、P21 mRNA表达的改变。

The number of the cells through the artificial matrix membrane in every group was counted to compare the change of the invasion capability among the experimental groups.

And I think that's why these Maya rulers were using Long Count time.

我认为这就是为什么这些统治者是玛雅人用长计数的时间。

It have programmable memorizer in which some operation instructions such as logic operation, sequence operation, timing, counting is saved and runs, and then it can control kinds of mechanism and process through input and output of digital or analog signal.

它采用可以编制程序的存储器，用来在其内部存储执行逻辑运算、顺序运算、计时、计数和算术运算等操作指令，并能通过数字式或模拟式的输入输出，控制各种类型的机械或生产过程。

I prefer counting from the e mergence of one integral anomaly to the emergence of the next.

我比较喜欢用一个完整的异常出现到下一个异常出现来计数。

Based on the classifying, identifying and counting of protozoan and metazoan, the relationship between microfauna community structure and operation performance of WWTP was discussed in detail, which might be used to indicate and assess the WWTP and be benefited to build control system oriented sludge population optimization.

在介绍微型生物分类、鉴定、计数的基础上详细阐述了微型生物种群结构与污水处理厂运行状态的相关性与内在联系，力求为今后利用微型生物种群结构特性来指示、评价污水处理厂的运行奠定基础，并对此方面的研究方向进行了展望。

Methods:Automated hematologic analyzer was used for platelet count if the URI flag was not due to the effect of microcyte,these samples were also c ounted under light microscope,and the results of these 2 methods were calculated for t test.

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
