A dramatic reorganization of interpolar microtubules into a highly organized central spindle between the separating chromatids is required for the initiation and execution of cytokinesis.

在向两极分离的染色单体之间的微管很规律地重组成高度有序的中心纺锤体，这是开始和进行胞质分裂的必要条件。

This MAAL-11 was used to construct the introgression line s and study the mechanisms of the recombination in the distantly related genome.

利用该单体附加系，构建了渐渗系群体，研究了远缘稻属种间染色体组间遗传物质重组的规律，并筛选出一些有着明显性状变化的渐渗系，主要结果如下： 1。

Scatchard analysis indicated that at least two different classes of recognition sites were formed during the course of self-assembly between monomers and templates through hydrogen bond or ionic bond.

Scatchard分析显示了功能单体甲基丙烯酸与模板分子阿替洛尔、美托洛尔在自组装过程中通过氢键和离子键形成了至少两类不等价的结合位点。

It was found that VAC can be smoothly photografted onto LDPE film with"film combination"system, e. g. conversion percent and grafting efficiency are 70％ and 76％, irrespcetively, with UV intensity of 5400μw/cm〓 and irradiation time of 3min. The reaction orders of polymerization rate to monomer concentration and photoinitiator concentration are about 1 and 0.76, irrespectively, showing that chain transfer reaction takes place with much ease in VAC/LDPE system.

发现利用本文所设计的方法可将VAC快速地接枝在LDPE膜表面，如在光强为5400μw/cm〓，光照3min时，转化率和接枝效率可分别达到70％和76％；聚合反应速率对单体的反应级数约为1，而对光引发剂的反应级数为0.76，说明VAC光接枝聚合中链转移反应占相当大的比例。

Headquarters islay Industry Park covers an area of 68.88 mu, construction area of 10,200 square meters have monomer products factory, 12,530 square meters of distribution centers, as well as the implication of a strong corporate culture of multi-functional administrative office building.

总部艾莱依工业园占地面积68.88亩，建有单体面积10200平方米的制品厂，12530平方米的配货中心，以及蕴涵着浓厚企业文化气息的多功能行政办公大楼。

KEF decided that by opting for computer-aided matching,it was possible to nominally select components so that if the network was +1dB a drive unit with a -1DB figure would be chosen to give 0dB overall change.

KEF於是决定采用电脑辅助配对，以利在一般情况下选取组件，使得若分频网路为+1db时，喇叭单体为-1db，最终得到0db的整体效果。

Needless to say, Kevlar represents a significant improvement over the polypropylene and paper used in most monitors for this price.

我们新的5低音单体是使用Kevlar纤维，而这个通常都是预留给高价位的监听喇叭所使用的。

During cell division,chromosome segregation is governed by the interaction of spindle microtubules with the kinetochore.

细胞分裂时，染色体的分离由纺锤体微管协同动点完成。从纺锤体两极发出的极间微管发生重排，在分开移向两极的染色单体之间形成严密整齐的动态结构：中心纺锤体。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
