不育

Not " the sea returns " the dazzling aureola of experience, not " 80 hind " the make public of millions upon millions plute of IT, the week 佺 of IT engineer one's previous experience likes not quite " show one's face in public ", more moment, he resembles an anchoret same, in his palm school of handsome network of international of Tianjin China Yo " fine carve of carve of essence of life " his " IT talent develops a project ", nowadays, this school with " rate of high obtain employment, high satisfaction is spent " market win initial success is taught in IT brand, won approbate, be known as " gold president " week 佺, the actual strength group that makes be worthy of the name of China Yo international with the outstanding achievement of arrogant person is gotten run person.

没有"海归"经历的耀眼光环，没有"80后"IT亿万富豪的张扬，IT工程师出身的周佺不太喜欢"抛头露面"，更多时候，他像个隐士一样，在他掌帅的天津华育国际网络学校"精雕细琢"他的"IT人才培养工程"，如今，这所学校以"高就业率、高满意度"在IT教育市场打响了品牌，赢得了认可，被誉为"金牌校长"的周佺，则用骄人的业绩成为华育国际名副其实的实力派领跑人。

The new materials(N/BBCC and J/BBCC) and their transmigration parent put up the similar phenotypes in development stage,morphological characters,POD enzyme activity,and so on.But differences in male fertility,proline content and relative conductance rate were existed among them,in which the development of androecium in N/BBCC was abnormal,showing serious male sterility,and the proline content and relative conductance rate in N/BBCC and J/BBCC were much lower than their transmigration parent,C/BBCC.

两个新材料及其轮回亲本C/BBCC在生长发育时期、植株外部形态特征、POD酶活性等方面表现基本一致，但在雄性育性、脯氨酸含量及相对电导率上存在着明显差异，其中N/BBCC雄蕊发育不完善、花药瘦小、药内花粉量很少且多为无生活力的畸形花粉，表现严重败育；J/BBCC和N/BBCC的脯胺酸含量及相对电导率明显低于其轮回亲本C/BBCC。

There are no significant differences of hsp70 and hsp90 expression between diapause and nondiapause insects.

数据分析表明，hsp70、hsp90在滞育与非滞育的虫体内表达量差异不显著。2。

Preapplication of forskolin or 8-Br-cAMP partly reversed the inhibition of IATP by hypotonicity, whereas preapplication of H89 had not effect on it.

5在细胞外液中加入forskolin或8-Br-cAMP预孵育，可以部分翻转低渗对ATP-激活电流的抑制作用，而H89预孵育则不影响低渗对IATP的影响。

The factors affecting the seed-set rate ofintersubspecific hybrids include embryo sac sterility,pollen sterility,anther dehiscence and non-synchronization of male and female sexual organsdevelopment in the same spikelet.

对水稻亚种间杂种及其稳定的多胚品系SB-1进行了细胞学、胚胎学和遗传学研究，主要结果如下：1、影响杂种低结实率的因素包括胚囊败育、花粉败育、花药不开裂和雌雄性器官发育进程不一致。

Considerable differences were found to be present among silkworm races with different voltinism and between the stock seed and the hybrid silkworm egg of the same race in their diapause characters and tolerance to cold storage.

不同化性的蚕品种之间以及同品种的原种和杂交种之间其滞育性及耐冷藏能力有较大的差异，一般来说，含多化性血缘蚕品种的滞育性低于二化性，二化性低于一化性，原种和原原种的耐冷藏能力低于杂交种，在作长期保存时应分别处理。

Males, for example, typically remain fertile when underfed, while females do not.

例如，当营养不良时，雄性一般保持可育，而雌性不能保持可育。

Fertile stamens 3, in a few flowers only anterior 2 fertile, posterior 1 depauperate or absent, often anterior 2 also depauperate; filaments densely white lanate; staminodes 3; antherodes 3-sect. Capsule ovoid, 1.5--1.7 cm, acute at apex.

能育雄蕊3，在数花内只前面的2枚能育，后面1发育不全或无，通常前面2也发育不全；花丝浓密的白色绵状毛；退化雄蕊3；退化花药 3全裂；蒴果卵球形，1.5-1.7厘米，锐尖的在先端。

1Unequal number of univalents with decreased degree of synapsis and lagging chromosomes occurred in meiosis.The abnormal chromosomal behavior correlated with heterogenicity gave rise to unequal allocation of homogenous chromosomes to daughter cells and resulted in the deletion of functional chromosoms,thus led to the occurence of a certion proportion of aborted pollens.(2)The interaction between genetic imbalance and such environmental factors as temperature,etc.,further drew forth physiological and even structrural imbalance,with abnormal development of pollen mother cells and tapetal cells,and consequently resulted in no or very few production of pollens.The difference in the interaction between environment and genotype reflected on the unstability of pollen abortion in different years.

1在减数分裂中有数目不等的联合程度较差的单价体以及落后染色体出现，这种与异质性相关的染色体行为异常，导致同源染色体向子细胞的不均衡分配，造成具功能染色体的缺失，从而引起毛白杨一定比率的败育花粉的产生；(2)遗传上的不平衡与温度等环境因子相互作用，进一步引发毛白杨生理乃至结构上的不平衡，花粉母细胞和绒毡层细胞发育异常，从而造成不产粉或产粉较少；环境与基因型互作的差异性导致了花粉败育的年度不稳定性。

To determine whether α1 and α2-adrenoceptors are located postsynaptically on renal vascular smooth muscle, a new method was developed as the following: the right renal vascular beds in the pithed rats were perfused with blood drawn from carotid artery at constant rate by a pump.

本实验用颈动脉血恒速满流毁脑脊髓大鼠单侧肾脏的方法，观察了高度选择性α_1受体阻断剂哌唑嗪和α_2受体阻断剂育亨宾与去甲肾上腺素、肾上腺素及电刺激肾交感神经对肾血管平滑肌的相互作用。哌唑嗪明显抑制电刺激引起肾灌流压升高，但尚存留一小部分既不能被增加哌唑嗪的剂量所阻断也不能被育亨宾所阻断。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
