In the late 1990s, the Chinese began ordering Russian Kilo class subs, then one of the latest diesel-electric design available.

It may have been made in the late nineteenth century as a special present for a dignitary.

它可能已在19世纪后期要人出席，作为一个特殊的。

SRG-L protein wasmainly observed in diplotene/pachytene spermatocytes, round and elongating spermatids.We can conclude this gene was activated during the early stage of meiosis, andtranscription of it kept high level during spermiogenesis.

因此初步判断这个基因在减数分裂早期被激活，转录在整个精子形成期维持较高水平的表达，有可能在精子发生后期起特殊作用，与减数分裂和精子变态成形相关。

In addition, remaining strength assessment and remaining life prediction are involved in direct examination and post-assessment of the Direct Assessment process.

另外，在外腐蚀直接评价过程的直接检查和后期评价步骤中涉及到管道剩余强度评价和剩余寿命预测。

The snail was found to have an indirect developmental type in the early development. The fertilized eggs were oval-shaped and discoidal cleavage. Embryonic development stages were divided into cleavage, blastula, gastrulae, trochophore, and intra-membrane veliger. Larval development stages included veliger, late veliger and crawling larvae metamorphosed to juvenile.

结果表明：黄口荔枝螺卵囊高度平均为7.33 mm，卵粒数量平均为165粒；黄口荔枝螺的早期发育属间接发生型，受精卵呈椭圆形，卵裂为盘状卵裂；在卵囊内，胚胎发育包括卵裂期、囊胚期、原肠胚、膜内担轮幼虫、膜内面盘幼虫；幼虫发育包括面盘幼虫、后期面盘幼虫和匍匐幼虫。

After the initiation of crack, the crack propagating of alloys with 0.5%Ce addition is accelerated evidently because of the appearance of needle rear earth rich phases which dissever the matrix and lead to the decrease of mechanical properties and thermal fatigue resistance.

加入0.5%Ce的合金在裂纹形成后期扩展速度明显加快，这是因为合金中出现针状富稀土相，这种针状相割裂了基体，使得合金力学性能降低、热疲劳抗力下降。

By the late nineteenth century," public domesticity" presented a solution to the growing diversity aboard trains.

到19世纪后期，"公共家务"为乘坐火车时不断增长的多种情况提供了解决途径。

Its embryo sac matures about 45 d after pollination.

在培养后期，外源激素对胚囊发育的影响很大。

It is another separate transform modulation, and could only be used in the later part of embryonic development.

它是另一种单独的位态调制。只在胚胎发育后期才有可能使用。

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。

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.
