繁殖群

These king penguins were part of a breeding colony photographed in the Falkland Islands, their spectacular coloration on full display.

这些国王企鹅是繁殖群的一部分拍照在福克兰群岛，它们的壮观的着色在完美的显示。

So the parameters are used to monitor state of swine herd production in a period. According to number of basal sow and practically reproducing state on current swine farm, using computer to calculate standardized swine herd data, compare with the fact data of hogpen swinery production.

原理是依据现有猪场的基础母猪数量和猪群的某个时间段初期的实际繁殖状态，通过计算机根据工厂化养猪理论参数模拟运算产生出标准猪群生产数据，将之与猪场猪群生产的实际数据相比较，并制出曲线对比图，从对比图中可直观看出猪群生产中的各个环节的优劣，这样就实现了对猪群生产的某个时间段的动态监测功能。

At the bookish assembly hosted by Secretary General Huang Chin-ying on January 3, Mr. Chang Pei-chen presented the first report on the Secrets of the 17-year Cicada written by Japanese Jin Yoshimura, a specialist of eco-mathematical model and biological evolution. The book was adapted from Yoshimura』s paper published in American Scientist in 1996, exploring the causes of evolution of magicicadas. Based on the duration of dormancy, magicicadas fall into two groups: the 13-year and 17-year periodical cicadas. Based on the principle of the survival of the fittest, as the lowest common multiple was larger, there were fewer groups proliferating at the same time to prevent damage of their ecological regularity as a result of hybridization.

1月3日读书会在黄晋英秘书长主持下，第一篇由张培臣先生报告《17年蝉之谜》，作者为日本人吉村仁，专攻生态数学模型与生物演化理论，本书改写自吉村仁於1996发表於《美国自然学家》期刊的论文，探讨质数蝉的演化缘由；依若虫期蛰伏於土壤中年份的不同，质数蝉大致可分为13年及17年两类，在天择情形下，因为最小公倍数比较大，同一时间的繁殖群相对比较少，可避免杂交而破坏其生态规律。

The frequency of genotype AA in prolific group and normal group were lower than low prolificacy group. It can be inferred that gene B made positive effect in prolificacy in Jizhong-goat, and gene A made negative effect in prolificacy.

高产群和普通群体的从基因型频率都比相应的低产群要低，可推测等位基因B对冀中山羊高繁殖性能有正向作用，而A基因对冀中山羊的繁殖性能有负向效应。

All pigs including breeding stock are removed from the farm, which is then thoroughly cleaned and disinfected, before being repopulated with clean pigs of a high health status.

将包括繁殖群在内的所有猪只转出猪场，之后进行彻底清洁消毒，然后再引入干净的健康状态良好的猪只。

Blood Pheasan lived in groups in winter In the breeding season the tendency living in groups also existed among non-breeding subadult males, breeding adult males or paired birds.

冬季集群活动。繁殖季节不参加繁殖的亚成体雄鸟、参加繁殖的成体雄鸟或配偶对往往也有集群活动的倾向。

Agonistic behavior and hierarchical formation of the Przewalski's Horse was conducted from the last ten-day in May to the last ten-day in June, 2007, when a new herd was formed and released into the second reintroduction site in Kalamaili Ungulate Reserve, Xinjiang. Focal sampling and all-occurrence sampling methods were used to observe and record the agonistic behaviors of the herd, and the dominance index of each individual was calculated.

2007年5月下旬至6月下旬，针对新组群并放归于卡拉麦里有蹄类保护区第二放归点的普氏野马繁殖群，采用焦点动物取样法和全事件记录法，观测记录了组群和放归初期繁殖群内个体间的争斗行为，以优势指数法确定繁殖群内的个体等级序列。

The number of grey heron Ardea cinerea L. was lower in 1990-1991 when water level was normal and birds had not bred yet than in 2000-2001 when water level was low at the reservoir and the breeding colony has existed.

与水库水位低、繁殖群已经形成的2000-2001年相比，苍鹭的种群数量在水位正常、尚未繁殖的1990-1991年相对较低。

The key area though, for maximising breeding herd output, is the service house.

但在关键领域，最大限度地繁殖群的输出，是服务的房子。

These king penguins were part of a breeding colony photographed in the Falkland Islands, their spectacular coloration on full display.

这些国王企鹅是繁殖群的一部分被摄取在福克兰群岛，它们壮观的染色丰满的显示。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
