尾脂腺

At the same time,we used a gas chromatography-electron capture detecter to determine accumulated organochlorine contaminant levels from penguin dropping-amended soil and organisms.

有机氯污染物主要分布在企鹅机体的脂质和脂肪中，其中脂肪和尾臀腺中的含量最高，脂肪中w，w，w和w分别为126.9～277.0，43.2～197.0，未检出～20.7和79.4～110.1 ng/g。

Female birds also showed overt preferences for the odor of male preen gland secretions or the 3-alkanol blend equivalent preened onto the plumage of a male over that of female counterparts.

另一方面，以往认为尾脂腺在鸟类中主要起到羽毛防水和折射不同波长光的作用，化学研究上也主要集中在对尾脂腺分泌的蜡脂成分的分析上。

In another test device with visible male bird stimulus, females chose the male with the 3-alkanol blend of males over the other male with female preen gland secretion, whereas did not differentiate their responses between the males with either this blend or male preen gland secretions.

正如论文评阅人所说：尽管很久以来就推测有些鸟的尾脂腺可能产生性信息素，但是该论文第一次提供了这类信息素组成的实验证据，也为以后的同类研究提供了参考方法。

The location and structures of sex-pheromone-producing gland in female H.insularis were studied by EAG,GC,SEM,and TEM.These studies showed that thegland situate in the intersegmental membrane between the eighth and ninthabdominal segments,and is an eversible abdominal fold;Many plump cones disturbon the surface of the gland.The glandular cells of 2-day old virgin female H.insularis are arranged in one layer,among which the central cells are columnarepithelial cells and flat on two sides.The nucleus is irregular elliptical.There isevident conjugation between cells and the involution is more in the basal membraneof cell.Microvilli are distributed on the cytoplasmic membrane and linked withendocuticle on which there are many layers of chitin,and the outer cuticule is staineddeeper.The cell contains bubbles,mitochondria,glycogen deposits,roughendoplasmic reticulum and smooth endoplasmic reticulum.

结合触角电位、毛细管气相色谱、扫描电镜、透视电镜等技术对小线角木蠹蛾雌蛾腹尖末端不同组织部位提取物的测定分析以及腺体位置和形态结构的观察发现：小线角木蠹蛾性信息素分泌腺位于腹部末端8～9节之间，是一个由节间膜特化而成的上皮结构，为一可外翻的腹褶，腺体表面分布着饱满的锥形体，羽化后2天未交尾的雌蛾腺体细胞呈单层排列，腹面中央由密集的柱形上皮细胞组成，细胞排列向两侧延伸至背部，其形状由柱形逐渐变为扁平形，细胞核为椭圆形，细胞与细胞间有明显的胞连接，细胞基底膜基褶较多，质膜上分布着微绒毛，并与内表皮连接，内表皮上有多层几丁质，外角质层染色较深，细胞质中含有空泡、线粒体、脂质粒、粗面内质网和光面内质网。

One hundred and twenty 8-wk-old cockerels with similar body weight were randomly were divided into four treatments: sham, left uropygial gland removal, right uropygial gland removaland both side uropygial gland removal.

本试验之目的系在探讨切除尾脂腺对台湾雄土鸡生长性状、血清脂质及电解质浓度之影响。

Female birds also showed overt preferences for the odor of male preen gland secretions or the 3-alkanol blend equivalent preened onto the plumage of a male over that of female counterparts.

另外一方面，以往认为尾脂腺在鸟类中主要起到羽毛防水和折射不同波长光的效用，化学研究上也主要集中在对于尾脂腺排泄的蜡脂成分的分析上。

I will endeavour to find you some assistance.

我尽力帮你找人帮忙。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
