Techniques in embryo technology (such as in vitro production of embryos and animal cloning) need large quantities of high quality oocytes. But the quality of in vitro matured oocytes from slaughtered animals is generally lower than that of the in vivo matured oocytes. It is usually thought that the reason for this poor quality in in vitro matured oocytes is the lack of capacitation during the dominancy of follicular development in vivo.

目前胚胎工程技术研究和开发(如体外生产胚胎和体细胞克隆等)需要大量高质量的成熟卵母细胞，但利用屠宰动物卵巢卵母细胞经过体外成熟培养而获取的卵母细胞质量还远不如体内成熟卵母细胞，其原因一般认为是由于缺乏体内主卵泡阶段的获能作用。

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。
