查询词典 metaphase

In addition, we studied the distribution of mitochondria in metaphase Ⅱ rabbit oocytes, zygotes and early embryos by two active mitochondria dyes and revealed the change of active mitochondria during early development of rabbit embryos. We also found that the distribution of microfilaments and microtubules have similar patterns to that of active mitochondria, which is an important basis for further development of animal cloning study using the recipient oocytes derived from rabbit.

Most sperm nuclei eventually developed into the male pronuclei, just like the normal sperms, except sperm nuclei in a few zygotes kept dense throughout the fertilization process. Dense chromosome body was seen at the nuclear area during the prophase of first mitosis, and in the middle of spindle at metaphase of first mitosis.

精子入卵后形成精核，大多能够逐渐解凝、液化并膨大，最终形成形态正常的雄性原核，但在第一次卵裂早期退化成浓缩的染色质小体，并在胞质分裂时随机地分配到其中一个子细胞里的分裂沟附近。

In this paper,we take TZ402 CIII oil group for example to show how water flooding affects horizontal well production dynamic of water-free oil production period and that initial stages and metaphase containing water is analyzed,in the end,we conclude that...

文章以TZ402CIII油组为例，分析了注水对水平井无水采油期、见水初期、中含水期生产动态的影响，认为注水是影响底水油藏水平井生产动态和开发效果的重要因素。

In this paper,we take TZ402 CIII oil group for example to show how water flooding affects horizontal well production dynamic of water-free oil production period and that initial stages and metaphase containing water is analyzed,in the end,we conclude that water flooding is an important factor affecting production dynamic of horizontal well and exploitation effect.

文章以TZ402CIII油组为例，分析了注水对水平井无水采油期、见水初期、中含水期生产动态的影响，认为注水是影响底水油藏水平井生产动态和开发效果的重要因素。

The technique is so simple,rapid,low cost and easy-to-use that it is bound to provide powerful technique for cotton genome sequencing.6.Researching on application of cotton FISH systems.There are two-pair large signals on the mitosis metaphase chromosomes and pachytene chromosomes of G.arboretum Shixiya 1 hybridized with 45S rDNA probe.

该技术方便快捷，成功率高，成本低，容易被掌握和快速推广，必将为深入进行棉花基因组研究乃至棉花基因组测序的最终完成提供强有力的技术支持。6。

Determination of photosynthetic pigments used 80% of acetone extraction method directly and the photosynthetic characteristics of using Li-6400 portable photosynthesis detector. Results showed that Returning the right amount maize straw stem into field was able to significantly restraint this year winter wheat flag leaf Chla degradation, to raise the flag leaf Chla/Chlb in the watery metaphase and late stage, to effectively restraint the photosynthesis rate decrease in the watery stage, to increase the pertinence of photosynthesis rate and pigment compared to others. However returning more maize straw stem into field was able to accelerate the retrogradation of chlorophyll and photosynthesis rate decrease then the yield declined.

结果表明：适量的玉米秸秆还田(9 000 kg/hm^2)可显著抑制接茬冬小麦灌浆中后期旗叶Chla降解，提高小麦灌浆中后期旗叶Chla/Chlb的比值，有效抑制灌浆期旗叶光合速率的下降，与其他处理相比，其光合速率与叶绿素的相关性得到加强；过量的秸秆还田(15 000 kg/hm^2)，加速了光合色素的降解，使得光合速率下降，产量降低；在各处理中，处理Ⅱ(9 000 kg/hm^2)产量最高。

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。
