倍性

Thus,it is important that elucidate the genetic control of the crossability of Chinese tetraploid wheat with rye.

因此，研究中国四倍体小麦的亲和性问题具有特殊的意义。

It is a special characteristic that many Chinese common wheat landraces showed a high crossability with rye.

中国六倍体普通小麦地方品种有一个比较独特的特征-存在丰富的高亲和性材料。

In cytogenetics, mosaicism is also sometimes referred to as mixoploidy.

在细胞遗传学中，镶嵌性有时也称为混倍体。

The deadliness of this ferocious virus is ten times more virulent than the worst flu virus !

至于变型的禽流感H5N1，更是闻者胆丧，该病毒的致命性是凶猛的，比最坏的流感病毒强十倍！

Data compression provides a significant (not less than 3 times less) decrease in the volume of data transferred via the network.

数据压缩提供了一个显著性（不低於3倍，以较低者为准）减少，在量传输的数据通过网络。

These culture conditions not only maintain the undifferentiated state and normal diploid karyotypes of BALB/c mouse ES cells effectively, but also maintain a series of their characteristics of murine stem cells. two different kinds of digestive methods and Two kinds of digestive juice with different concentrations were designed to dissociate proliferous inner cell mass and ES cell clonies deriver from dissociative ICM.

这一培养条件不但有效地维持了ES细胞的未分化状态和正常二倍体核型，而且维持了其作为多能性胚胎干细胞的一系列特征；实验设计了两种离散方法和两种浓度的消化液，用来离散增殖的ICM和ICM离散后出现的ES集落。

MHz is applied, the dichroic angle can be enhanced by about 7 times.

MHz时，二向色性角可增大约7倍。

In the paper, the orientation behaviors of polyurethane film were investigated by means of infrared dichroism measurement.

采用红外二向色性法对聚四氢呋喃醚二醇/ 4 ，4′-二苯基甲烷二异氰酸酯系聚氨酯薄膜样品的拉伸取向行为进行了研究，结果表明，随着拉伸倍率的增大，CH2 角基团发生取向。

Sonicated bacterial extract caused a modest, less than 1 fold, increase in IL-8 secretion by digitonin-untreated A549 cells. In the digitonin- permeabilized A549 cells,Sonicated bacterial extract strongly induced the expression of IL-8,a 3 fold increase over the control.

经digitonin处理使细胞膜通透性增加后，Kp培养上清及菌体成分刺激细胞IL-8的作用都增强，菌体成分刺激IL-8效果更为显著，为对照的3倍，而培养上清作用相对较弱。

In diploid cells, there is a pair of sex chromosomes; the remainder are termed autosomes.

在二倍体细胞中，有一对性染色体，其余的都是常染色体。

Do you know, i need you to come back

你知道吗，我需要你回来
