不败

The disintegration of tapetal cell was relayed, the inner wall of tapetal cell secreted fewer Ubish bodies.

花粉败育过程中，小孢子液泡膜和细胞质膜断裂破碎，细胞质解体，线粒体、质体、内质网等细胞器解体或退化，绒毡层持续不解体，并缺少乌氏体的分泌。

In the study, a set of near isogenic lines of CMS-S, S-Mo17Rf3Rf3 and S-Mo17rf3rf3, were adopted, and TdT-mediated dUTP nick-end labeling, in situ immunolocalization of cytochrome c and DNA ladder assay were employed to study the programmed cell death process on cytology and DNA level. The microscope observation evidenced that tapetal cells of fertile anthers kept intact until microspores, and then were disintegrated on later developmental stage.

S型细胞质雄性不育系的一对近等基因系S-Mo17Rf3Rf3 和S-Mo17rf3rf3为材料，采用TdT介导的dUTP DNA末端标记、细胞色素C免疫原位杂交和DNA寡聚核小体片段电泳等方法，分别在细胞学水平和DNA水平上研究了玉米CMS-S小孢子败育的细胞程序性死亡过程。

If we do not work hard, we 'll be defeated by the rivaling business firms.

如果我们不努力，我们就会败在与我们竞争的商行手下。

The proliferation of the anthers and pollens were distinctly dysplastic. During the prophase of abortive pollens, the tapetums and middle layers of quadrants separated; during metaphase, the microspores were development arrest; during anaphase, the tapetums and microspores gradually disappeared after combination, the anthers finally turned into drying and shriveling to be unable to form pollens.

如主茎开花初期提前1~2d，花萼和雄蕊个数为4~6个，花药室数为2~4个，开花后花药呈白色或淡绿色，表面无皱纹，并延迟脱落；其花药和花粉发育明显异常，败育初期在四分体期绒毡层与中层分离，中期小孢子形成时期发育停滞，后期绒毡层与小孢子粘连后逐渐消失，终期花药干瘪，不能形成花粉。

For those among you who sneezed and missed the Mariners' win streak, it's too late.

那些因为打了个喷嚏，不小心错过了水手止败的一场，不好意思，太迟了。

The financial demands of raising a child require that money you otherwise might use to prepare for retirement, or to save for a nicer house, a sportier car or a swankier vacation, must, out of necessity, be earmarked for Lego sets and pediatrician visits and school uniforms and Christmas toys and a college savings account and a minivan and a trip to Disneyland ... and lots of, well, chicken nuggets.

养孩子的钱都是你是从别的地方生生卡下来的，你本可以用它们安排退休生活、存起来买栋心仪的房子、&败&辆跑车或外出度个拉风的假期，但如今你必须破费买乐高玩具、看儿科医生、买校服和圣诞玩具、攒大学学费、添辆家用迷你箱车以及拉家带口地去迪斯尼乐园游玩…………等等等等，许许多多，数也数不过来。

The declination in the kernel yield of corn underwater stress at stage of tasselling was mainly resulted in the reductionof kernel numbers per ear which increase of bald tip and reduction ofgrain numbers per row caused . It showed that drought causedunencountering of flowering phase and increase of abortive kernels.

研究表明，穗粒数的减少是玉米抽雄开花期水分胁迫下产量降低的主要限制因子，而秃尖增长和行粒数减少是穗粒数降低的主要因素，说明干旱导致雌穗发育受阻，花期不遇，籽粒败育率增加。

I'm not one to harp on umpires," Torre said,"but this one got me.

他说：「我不是那种会对裁判怨声载道的人，但这次我真的败给他了。

It was suggested that one of the radical reasons resulting in microspore abortion of alloplasms was the disorder between nucleus and cytoplasm, which caused unbalance of enzymatic metabolism, decrease of activities of SOD and CAT, and damage of membrane systems led by accumulated active oxygen.

异质系核质关系不协调，酶代谢失调，SOD、CAT活性下降，活性氧积累导致膜系统损伤，可能是异质系花粉败育的根本原因之一。

All the long sleeves and cardigans i brought with me to hong kong are useless! but i guess that provides one more reason for me to shop huh?

我带来香港的长袖还有毛衣现在完全派不上用场，不过这样也好，如此一来就多个理由去败家。

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。
