分体

The cytokinesis of microspore mother cell during meiosis is of simultaneaous type.

小孢子在四分体中的排列方式属四面体型。

In diplotene the pairs of chromatids begin to separate from the tetrad formed by the association of homologous chromosomes. Chiasmata can often be seen at this stage.

双线期时，配对的染色单体开始从四分体中分离，此时常可见染色体交叉。

Of or relating to a dyad or based on two.

属于或关于二分体，或以二为基础。

As a result, dyad spore s formed

结果形成二分体孢子。

In order to make ear plugs are also portable, this product will be designed to become a sub-body shape of the card.

为了使耳塞也同样便携，这款产品将其设计成了分体的卡片形状。

Calculate the Einstein tensor from a given metric in a tetrad or in a coordinate frame.

读，写，简化，替代和区分数学表达式；定义张量和张量运算法则；从一个给定的公制中在四分体或者同等结构中计算Einstein 张量。

In research and teaching of elastic collision of two particles,with the help of the graphical method, the effect is more audio-visual, imaginal,succinct and thorough.

两个粒子的弹性碰撞问题，若辅之于图解法，则对问题的研究、讨论以及课程教学等，都显得更加直观、形象、简洁和透彻，充分体显出它的优越性。

Seeds 0.3-0.6 mm, free, not embedded in endocarp; pollen in tetrads

种子0.3-0.6毫米，离生，不嵌入在内果皮里；在四分体里的花粉 8

More calcium precipitates were located in the epidermis, endothecium and tapetum of the sterile anther than in those of the fertile anther. Longitudinal inner cell wall of the sterile anther became thicker than that of the fertile anther at the dyad stage and uninucleate pollen stage.

到四分体与单细胞花粉时期，不育花药的木质部细胞的次生加厚壁上有较多的Ca2+沉淀，连接组织中的Ca2+沉淀也大大增加，所有不育花粉外壁较厚而发育都不正常。

The anther possesses four microsparangia with its wall composed of four layers: epidermis, endothecium, middle layers and a 2\|nucleate celled tapetum.

绒毡层细胞在发育后期由单核分裂为2 核，多原位解体，为腺质型；但大约有12％小孢子囊的绒毡层在小孢子四分体释放时期进入花药室内，成为变形绒毡层。
