发情期

During oestrus or direct contact, panda show their likes or dislikes, their intimate through different frequencies of clicks, howls, roars, and baas.

在发情期或直接接触时，大熊猫通过发出不同频率的吱吱叫、嗥叫、吼叫、咩叫声等，表达厌恶、亲近、喜欢等各种情感。

Jinshan feed with pearl millet, millet, barnyard grass-based, family farming millet or millet can be used daily 60%, barnyard grass 40%, mixed feeding, estrus fed eggs, rice, sand, oyster powder, green feed, as appropriate, feeding, feeding chicks approach, powder fed 5-6 times a day, each compartment 2 -3 hours.

On Beltane Eve, a very long time ago, the young men of the village would go into the woods and 15don 16stag 17horns and skins in a kind of "play fight" with the 18rutting stags to see which was bravest.

很久很久以前，在五朔节的前夜，村子里的男人会到树林里去，头戴雄鹿角，身披雄鹿皮，然后与正在发情期的雄鹿打一种"游乐仗"，比一比谁最勇敢。

In infundibulum and ampulla, the mPGES-2 staining from days 3 to 5 was very weak. During estrous cycle, mPGES-2 immunostaining in infundibulum was weak at diestrus and comparatively stronger at estrus. In ampulla, the immunostaining was nagtive in diestrus and weak in estrus.

发情周期中，mPGES-2 蛋白在发情间期伞部弱表达，在发情期伞部较强表达；在发情间期壶腹部不表达，在发情期壶腹部弱表达，与Western blot 检测整个输卵管的结果基本一致。

It was found greater expression of NRP2-1 and NRP2-2 in pituitary, ovary, uterus and oviduct of ruttish Erhualian than corresponding tissues of ruttish Duroc, which suggested enhancing expression of NRP2 was favorable to increasing litter size. But the difference of NRP2 expression was not significant between two breeds, which suggested the key phase that NRP2 affected litter size was not oestrum probably, or NRP2 could enlarge cell signals and finally affect litter size ascribe that it was the receptor of nerve axon guidance factors.

NRP2-1和NRP2-2在发情期二花脸卵巢、子宫、输卵管中的表达量均大于杜洛克相应组织的表达量，推测NRP2表达水平高可能有利于提高产仔数，但两品种间表达差异不明显，推测NRP2影响产仔数的关键阶段可能不是猪的发情期；另外，NRP2 是神经轴突介导因子的受体，这些神经轴突转导的信号往往有级联放大的功能，虽然NRP2-1和NRP2-2在二花脸和杜洛克卵巢、子宫、输卵管中的表达差异不大，但二花脸有可能通过神经系统转导信号的级联放大最终引起一些效应激素或蛋白的急剧增加，从而提高排卵率或产仔数。

In the pituitary, the pattern of ghrelin mRNA expression during oestrous cycle markedly decreased in the estrus and metestrus. In the ovary, ghrelin mRNA exhibited with the highest level in the diestrus and the lowest in the proestrus, which was different from those in the hypothalamus and pituitary.

下丘脑ghrelin mRNA的表达在发情前期水平最高（p 0.05），发情期最低；在垂体，发情前期和间情期mRNA表达水平明显高于发情期和发情后期（p 0.01）；而卵巢中Ghrelin mRNA表达模式不同于下丘脑和垂体，在发情前期水平最低，然后逐渐升高，在间情期表达水平最高（p 0.01）。

The firing rate of NE-ergic neurons in the ovariectomized female rats was lower than that in the estrus and diestrus female.

摘除卵巢雌鼠LC中NE能神经元放电频率比发情期、非发情期雌鼠均显著减少，但对雌二醇的反应与非发情期雌鼠相似，仍为放电增加。

After intravenous administration of estradiol, the firing rate of NE-ergic neurons in the locus coeruleus was decreased in the estrus female rats, but increased during the diestrus phase or in ovariectomized rats.

静脉注射雌二醇可使非发情期雌鼠蓝斑中去甲肾上腺素能神经元放电增加，发情期雌鼠LC中NE能神经元放电减少。

Breeders may do a second litter 18 months after the first, which is usually the second season after the first, and most Salukis in reality will only have two litters in a lifetime.

育种人可能会在她首次生产18个月之后让她再次怀孕，这通常也是第一次发情期后的第二个发情期。事实上，大多数萨路基一生只产两窝小狗。

In order to study the expression of Gonadotropin-Releasing Hormone in the hypothalamus of estrus milk goat.

为了研究促性腺激素释放激素在发情期奶山羊下丘脑中的表达特点，采用超敏的免疫组化链霉素抗生物素蛋白-过氧化物酶法研究GnRH免疫反应神经元在发情期山羊下丘脑中的分布。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
