Chromosome segregation in mitosis is orchestrated by dynamic interaction between spindle microtubules and the kinetochore. Proper alignment of chromosomes and their segregation in mitosis also relies on cohesion between sister chromatids.

在有丝分裂中，染色体的分离通过纺锤体与动点之间的相互作用来调节，染色体的正确排列与分离还依赖于染色单体之间的粘连。

In comparison of the NS gene analysis, changes of the amino acid sequences are lesser than those in the HA gene. The phylogenetic analysis of NS gene is not form different linage between B/Taiwan/3143/97 and B/Taiwan/21706/97, and all isolates were closed to each other.

由HA基因序列的比较中发现，新的分离株的突变位置与B/Taiwan/3143/97大部分都类似，但突变点相较之下数目较少；而在演化树的分析中，新的分离株会与B/Taiwan/3143/97聚集，形成一新的群集。

So it is assumed that the E-box might be associated with the enhancement of transcription activity.Here, the LTRs of WH17 ,DLA-25,DLA-118 and LTR with single mutation in the E-box motif were separately cloned into pCAT-Basic vector resulting in a series of recombinant plasmids containing CAT reporter under the control of different versions of LTRs.

通过对EIAV分离株WH17的LTR与L株、DA和DLA株的LTR序列进行比较，发现其在在U3-R结合处多一个E-box基序，推测该基序的变化可能会起到促进转录作用，为此将EIAV强毒株(DLA-25)、驴白细胞弱毒株(DLA-118)、EIAV分离株WH17以及U3-R结合处的E-box基序点突变的LTR分别克隆到pCAT3-basic质粒中的报告基因氯霉素乙酰转移酶的上游，获得一系列受不同LTR控制的CAT表达质粒。

In the analysis of dynamics cutting angle, the following phenomenon is discovered first time: the minimize of dynamics clearance angle is not monotone decreasing with the vibration frequency , and appear peak value periodically, which exist is the disseparation region and approach the separation region.

在对振动钻削中切削刃上各点的动态角度的分析中，首次发现在振动钻削过程中动态后角的最小值不是随着频率或频转比的增大单调下降，而是周期性的出现波峰值，这些波峰值都出现在不分离区，而且是接近于分离区处，这是由振动钻削过程中的变速特性引起的。

By using combinationo of virus isolation and identification of diseased tissu nucleic acid dot blot ,the so-called infectious proventriculus disease was demonstrated to be a new typeof avian infections broncchitis.

通过病原分离、鉴定，血清学检测，病原免疫原基因分离、鉴定，病料组织核酸点杂交等方面诊断研究，证明本病是一种新近报道的腺胃病变型为特征的禽传染性支气管炎。

Therefore, the indicatrixes of the liquid segregation mainly with immiscibility are the saltatory variation type of REE model evolution and the sep arative feature of main-evolution trend line either with sub-evolution trend line or with composition point of Li-F granites in the diagrams of REE-n and La/Sm-La.

因此，不混溶为主的液态分离标志是稀土模式演化突变类型和Li-F花岗岩在REE -n、La/Sm-La图解中主演化方向线与次演化方向线或与成分点呈分离特点。

Compared with 11 other isolates reported in GenBank, there was slightly variation in the nucleotide sequence of Omp25 gene of wapiti's isolate. The identities of nucleotide sequence and deduced amino acid sequences among 11 strains were 99.1%-99.4% could 99.2%-99.5% respectively.

与GenBank中已经登录的布氏杆菌其他11个分离株相比，马鹿布氏杆菌分离株Omp25基因变异较小，以散在的点突变为主，Omp25基因核苷酸和推导氨基酸序列的同源性分别为99.1%-99.4%和99.2%-99.5%之间。

Aiming at precision measurement of cylindricity,this paper puts forward a kind of method which can sep- arate the cross- section roundness error,the radius error of different cross sections,the initial coordinates of least square centers of measured cross sections and can reconstruct the pattern of the measured cylinder,i.

本文针对圆柱度误差的精密测量，提出了一种可分离截面圆度误差、截面半径差和截面最小二乘圆心初始位置并重构出被测圆柱形貌的方法，即三点法圆柱度误差分离与重构技术。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
