Eagan grew up in a poor family in the U.S. city of Denver, yet he made his way through the best universities: Yale, Harvard Law School and Oxford. In 1920, Eagan defeated Sverre S?rsdal of Norway to win the light heavyweight boxing championship at the Antwerp Olympics. Later he became the first American to win the amateur championship of Great Britain.

伊根出生在美国丹佛的一个贫苦农主家庭，但是他通过努力，考取了世界最好大学：他曾经就读于耶鲁、哈佛和牛津大学，这些教育让他后来成为一名成功的律师。1920年，在比利时的安特卫普举行的第七届夏季奥运会上，伊根在男子轻重量级拳击决赛中击败了一位挪威选手，夺得一枚夏季奥运会金牌，随后，他成为第一位在大英业余拳击锦标赛上获得冠军的美国人。

Using GSA-〓 lectin histochemistry, the first appearance of microglia occurred at E13, usually stained as scattered amoeboid cells. From then on, the number of microglia increased steadily, reached a peak at postnatal day 7 (P7), and then reduced gradually to adult level. Generally the morphological form of microglia undergoes transformation from early rounded or ameboid to adult resting ramified as they differentiate during development.

使用凝集素GSA-〓亲和组织化学染色，本实验最早观察到小胶质细胞在胚胎13天（E13），为散在分布的圆形或阿米巴样细胞，随后细胞数量逐渐增多；总体而言小胶质细胞的形态遵循着由圆形或阿米巴样逐渐转向纤细分枝状的演变规律，不同阶段细胞形态各有其特点，在不同区域也存在差异；小胶质细胞的数量在生后第七天（P7）达到高峰，其后开始逐步降低直至成年。

ELISA showed that antibody responses induced by propolis vaccine were faster than that of oil-emulsion vaccines and aluminum hydroxide vaccines;antibody responses induced by oil-emulsion vaccines were longer in duration than that of propolis vaccines and aluminum hydroxide vaccines;the maximum antibody responses induced by oil-emulsion vaccines and propolis vaccines were higher than that of aluminum hydroxide vaccines;Antibody levels were all significantly boosted by revaccination of these vaccines and in addition to this,oil-emulsion vaccines showed longer antibody duration.

这七种疫苗在抗体产生速度方面以蜂胶苗较快，而油剂苗和铝胶苗免疫后抗体上升速度较慢；在抗体水平的维持能力方面，油剂苗较蜂胶苗和铝胶苗更强；在产生最高抗体水平方面，油剂苗和蜂胶苗能力相当且较铝胶苗为高；在加强免疫的效果方面，这些疫苗二次免疫所产生的抗体水平均较一次免疫更高，蜂胶苗和铝胶苗在第93天时的二免抗体水平已降至同一免相当，但此时油剂苗有着较一免更高的二免抗体水平。

Some weeks before the presidential election, the 60th and the 7th Kuomintang armies retired on the city of Changchun with their heavy American equipment while a small force of the People's Liberation Army of General Lin Piao took up positions of siege around the city.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
