发情期

Males and females only commingle during mating season, otherwise they live solitary existences.

公兽和母兽只在发情期交配，平时独来独往。

Then there are March hares whirling and hissing at each other in the rivalry of love-making. If any creature knows that Spring is here, it should be the March hare.

然后是发情期的野兔在急速奔跑，为了竞争配偶而互相发出嘶嘶声，假如真的有一种动物知道春天是在这里，那它应该是三月的野兔。

The results showed that UEA-1 receptors were mainly locolized on the surface of the glandular and luminal epithelium.

UEA-1受体在休情期犬子宫内未见表达，而在发情期犬子宫内膜腔上皮和腺上皮内的表达量很高。

But in fact, the fellatio is humanity's unlearned behaviour, all female animal when oestrus period, the reproductive organ nearby can secrete the Fellow Mongolia to attract the male gender to be close, and lets the male gender contact the female with the mouth reproductive organ, the amusement period of time, only then starts the copulation.

但事实上，口交是人类的本能行为，所有的雌性动物在发情期时，生殖器附近都会分泌费洛蒙来吸引雄性接近，并让雄性用口去接触雌性的生殖器官，玩乐一阵子，才开始交配。

This milch cow is in oestrum.

这头奶牛处于发情期。

The relation between different BMPRIB genotype in Small Tailed Han sheep and FSH receptor or LH receptor mRNA levels during the oestrum was studied by semi-quantity PCR.

4利用半定量PCR技术研究发情期小尾寒羊BMPRIB基因型与ERα和PR的mRNA表达量的关系。

And meanwhile, many thanks for Teng Ge LI, he solved a problem that we lacked of women ( Checking the number of people before start was very vapid, there were more than ten men who were in the period of oestrum, just there was one lady, but she was the leader).

也同时鸣谢，腾格里解决了我们此次队伍严重缺女丁的问题（出发前清点队伍实在无趣，十几个正处在人生情感发情期颠峰的男生只配备了一个蛛蛛，还是领导）。

Methods1. Compared with adult female rats, aged female rats without oestrum were chosen by using RIA technology and sexual hormone was changed remarkably. Theses aged rats were divided into three groups（GNK group, HRT group and control group）. Treated them respectively with GNK, nilestriol and distilled water 3 months.

通过用阴道脱落细胞涂片检测发情周期的改变，放免法测定血清性激素的水平，与正常青年雌性大鼠比较，选择阴道脱落细胞无发情期改变，血清性激素水平有增龄性改变并且差异有显著性的老年雌性大鼠作为研究对象，分别用中药复方更年康和尼尔雌醇灌胃3个月，观察中药复方更年康对老年雌鼠的治疗作用。2。

The result showed FSH receptor mRNA levels from the right ovary of BB (1.14 ± 0.11) ewes were higher than those of AA (0.44 ± 0.11) and AB (0.36 ± 0.08) ewes (P.01); LH receptor mRNA levels from the right ovary of BB (0.42±0.02) ewes were significant higher than those of AA (0.23 ± 0.02) and AB (0.25±0.04) ewes (P.01), but there were no significant difference in the left ovary among the genotypes during the oestrum.

结果显示：在发情期BB型右侧卵巢PR的mRNA水平(0.81±0.10)显著高于AA(0.43±0.10)型(P.05)，左侧卵巢各基因型间无差异。

While there was no evidence of subordinate stress, one oryx which had been dominant but then was excluded for two years had three fold higher testosterone and corticosterone than the other males at estrus

没有证据表明从属个体压力的存在，一只弯角长角羚曾经是优势个体，但是后来有两年不是优势个体，与其他雄羚相比，这只雄羚在雌性发情期的睾酮和皮质酮水平有3个交迭出现的峰值

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
