减数的

The other type was somatic meiosis which was analogous to that existed in the process of gametogenesis, and characterized by the pairing and synapsis of homologues chromosomes.

另一种类型是体细胞减数分裂，这种类型类似于大小孢子发生过程的减数分裂，如第一次分裂前期也有染色体的联会和配对。

Results indicated : The meiosis stages of megaspore of white poplars are different, while there was a association between MMCs and PMCs meiosis in the same hybrid.

研究表明，不同白杨的大孢子母细胞减数分裂进程存在差异性，而同一树种的大、小孢子母细胞减数分裂进程存在时序性相关。

Meiotic prophase ⅠⅠ more complicated, many of the special process of meiosis have occurred in this period.

减数分裂Ⅰ前期Ⅰ比较复杂，减数分裂的许多特殊过程都发生在这一时期。

These mainly involve the periodic change of ribosome den- sity,the dedifferentiation and redifferentiation of both plastid and mitochondrion during the process of meiosis.

在这个过程中，小抱子母细胞经减数分裂产生大致相同的4个减数抱子，并逐渐发育成雄配子体。

Reduction division The first division of meiosis , including prophase, metaphase I, and anaphase I. It results in a haploid number of chromosomes gathering at each end of the nuclear spindle.

减数分裂：减数分裂中的第一次分裂，包括分裂前期，中期 I 和后期 I ，形成单倍数目的染色体在每一个核纺锤体末端聚集。

Even's air-drying method for meiotic preparations from germ cells of mammalian testes improved by our laboratory was used and dynamic change of division figure of prophase 1 in the mouse treated by testosteronic propionas and stilbestrol was observed.

采用本室改良的Evens哺乳动物睾丸生殖细胞减数分裂空气干燥法制片技术，观察了用丙酸睾丸酮和已烯雌酚处理小鼠第一次减数分裂前期分裂相染色体的动力学变化。

Tic division of F1 hybrid was normal ,anucleate cells and cells with micronuclei which were produced by asymmetrical separation of chromosomes were observed at the second meiotic division.

结果表明，杂种F1减数第一分裂基本正常，在减数第二分裂观察到由于染色体不对称分离产生的无染色质和仅带有微核的子细胞。

At time of 5mm length of alabatrum, the miosis in microsporecyte and the sex differentiation was found, thus in female flowers, pollen mother cell showed a abnormal meiose then the pollen cells gradually disintegrated, final, contabescence had taken, and in male flowers, the stamen normally developed.

在幼蕾长到5mm左右，即花粉母细胞开始减数分裂时，出现花性别的分化，雌花中雄蕊花粉母细胞不能进行正常减数分裂，进而花粉细胞逐步解体而导致雄蕊败育；雄花中雄蕊发育正常至性成熟。

The cytogenetics of interspecific hybrids among the four cultivated cotton species were studied in this paper and results are as follows: The diploid interspecific hybrid (G. arboreum×G. herbacium) F〓 had a four-chromosome-ring at the meiotic metakinesis. The synapses of tetraploid hybrid (G. hirsutum ×G. barbadense) F〓 was found to be regular, which mainly formed bivalents, sometimes some univalents, multivalents and chromosome bridge.

四个栽培棉种间杂交种F〓的细胞学观察结果表明，F〓减数分裂中期Ⅰ，形成一个环状四价体，直接证明了亚洲棉与草棉之间存在一对相互易位；F〓减数分裂中期Ⅰ联会基本正常，主要形成二价体，偶尔出现一些单价体和多价体，以及染色体桥。

Methods: The physical volume of 24 bicuspids extracted for orthodontic purposes (16 were imaged with the i-CAT and 8 with the CB MercuRay before extraction) was determined using water displacement technique.

选择10例正畸减数病例拔除的双尖牙24颗，采用排水法物理测量其体积(volume of water， Vw)，其中7例（16颗牙齿）在减数前采用i-CAT进行三维扫描，3例（8颗牙齿）使用CB MercuRay。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
