Spotted seals called Western Pacific Cod Seal,belong to Carnivora,Caniformia,Phocidae,Phoca,They are second-class protection animals of China.

斑海豹又称西太平洋斑海豹，属食肉目、犬形亚目、海豹科、斑海豹属，是唯一能在我国海域繁殖的鳍足类动物，属国家二级保护动物，渤海辽东湾是全球斑海豹8个繁殖区之一。

The phylogenetic analysis of 22 ND4L sequences of Phocidae from GenBank showed that there are two clades (which belong to Northern Group and Southern Group) supported by relatively high bootstrap value and there are more closed relationship between spotted seal and harbor seal.17 haplotypes with 717bp were obtained from the mtDNA control region, adjacent proline and a portion of the threonine tRNA genes of 46 individuals.

利用从GenBank中下载的22个海豹科动物的ND4L基因序列的系统进化分析表明，海豹科动物分为南半球和北半球两大类群，斑海豹与港海豹为北半球种类，亲缘关系最近。从46个辽东湾斑海豹线粒体DNA控制区和苏氨酸及脯氨酸tRNA基因717bp片段的测序，得到17个单倍型。

"Either of the two largest pinniped species: the northern elephant seal, of coastal island s off California and Baja California, or the southern elephant seal, of sub-Antarctic regions."

鳍脚亚目海豹科两种最大的鳍脚类水生哺乳动物的统称，即︰北方小吻象海豹，主要栖于加州和墨西哥下加利福尼亚的沿海岛屿；南方象海豹，栖于整个南极附近地区。

Populations of spotted seals in a breeding region on Bohai sea and 3 habitats: Shuangtianzhi river mouth of Northern Liaodong Bay, Huping island of Lushun and Dalian and Miaodao islands in Bohai Sea Channel were surveyed from 2003 to 2007 and also their summering habitat on Korean Bak - ryung island on Northem Yellow Sea.

2003—2007年，对斑海豹在渤海的繁殖区和辽东湾北部双台子河口、大连旅顺虎平岛及渤海海峡的庙岛群岛3个栖息地，分别进行了斑海豹种群数量调查，并对黄海北部韩国白翎岛斑海豹度夏栖息地进行了现场考察。

This team is in search of elusive bearded seals, an affectionate and playful seal species that spends nearly all its life either in the water or drifting on Artic ice floes.

这个团队在搜寻难以捉摸的髯海豹。髯海豹是一种很深情的和爱嬉戏的海豹，它们几乎花费所有的生命精力在水中或在北极的浮冰上漂流。

这个小组是为了寻找令人捉摸不透的胡子海豹而成立的，胡子海豹是一种顽皮可爱的海豹，它们的一生几乎都在水中或者北极圈的浮冰上度过。

Studies of the Weddell seal in the laboratory have described the physiological mechanisms that allow the seals to cope with the extreme oxygen deprivation that occurs during its longest dives, which can extend 500 meters below the ocean's surface and last for over 70 minutes.

5，关于威德尔海豹特殊的生理机制，在实验室里对其进行的研究已作过详细的描述。该生理机制使海豹可以适应长时间潜水时出现的极度缺氧。海豹长时间潜水时最深可达水面以下500米，时间可持续70多分钟。

Humans hunt down seals brutally mostly for obtaining some insignificant things such as sealskins, seal flesh, seal oils.

海豹皮海豹肉、海豹油、海豹鞭，人类为了这些无关紧要的东西，惨然地剥夺了它们的生命

The results showed that the spotted seals in Liaodong Gulf maybe belong to an independent population and no gene flow or exchange of female individuals occurred between those along Sea of Japan and Sea of Okhotsk.

初步表明，辽东湾斑海豹与日本海、鄂霍次克海斑海豹是属于不同的地理种群，或者辽东湾斑海豹同这两个海区斑海豹未发生基因交流或者雌性个体的相互交流。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
