摘要：The Adventure of Huckleberry Finn written by mark Twain is considered as representative novel with initiation theme in American literary circle. It has taken the fancy of the readers throughout the whole world since it was frequently printed and widely translated. In the story, mark created an image of a boy named Huck who had an unexpected adventure by sailing a raft down the Mississippi River with his friend, Jim. After experiencing the adventure, Huck finally became mature. The present paper gives a brief introduction of the story. Then, the paper mainly explores how Huck established his identity from the following aspects: his disapproval to slavery and his consciousness of moral development and obligation.

摘要：Edna O"Brien (1930- ), an Irish novelist, poet, and short story writer, is considered as a pioneer for her frank portrayals of women and the most gifted woman writing in English at her time. Her first novel, The Country Girls (1960), was an immediate success. Her writing is lyrical and intense with passions and aspirations. Set in Britain, the short story Cord describes a story about how the mother and the daughter got along in the short reunion after a long separation. The paper mainly explores different religious values, cultural values, and social values between them which caused irreconcilable conflicts. The present paper concludes that the "Cord", the blood tie, can never get rid of the spiritual barrier. Only mutual understanding can eliminate the gap and acquire a harmonious relation between parents and children.

摘要：George Eliot(1819-1880), is one of the most highly praised novelists in the literary world in the 19th century because of her unique position in English literature. She wrote a large quantity of works of the highest merit and of far-reaching influence. Her attitude towards feminism has aroused wide attention and has been discussed hotly among feminist critics in different countries. The Mill on the Floss, which first appeared in1860, is regarded as the most excellent autobiographical novel of Eliot. The ideology of male power in the patriarchal society during the Victorian Era is internalized in people"s heart, which brings huge influence on maggie"s female mental state. This paper aims to discuss the causes of maggie"s feminist thoughts and manifestation of her feminism, thus, the influence upon women in her times. The paper concludes that Eliot was a great female author full of pioneering feminist thought from the example given by maggie in The Mill on the Floss.

摘要：The Chinese Dream, adopted by General Secretary xi Jinping, was used and spread in China. It is about Chinese prosperity, collective effort, socialism and national glory. It is also about the welfare, wellbeing, and quality of life of every Chinese. Academics in higher education in China are facing changes both across the globe and in China, they must take the challenges. This paper does research on wellbeing of the academics from the aspects of the definition of wellbeing, the situation both in the world and in China, the Chinese concept of happiness, the possible influence of Confucius moral standards on wellbeing of Chinese. This paper may help school leaders implement policies that foster effective work environment in the new era in China.

摘要：植株根系的形态和生理特性决定着其获取养分和水分的能力,分析麦田冬小麦根系形态特征、根系活力对水氮的响应及其与地上干物质积累、产量和氮素利用的关系,有利于构建合理的冬小麦根群结构,促进根冠协调生长并提高氮肥利用效率。在麦田定位试验基础上,采用裂区试验设计,设置2个灌溉主处理(W0:全生育期不灌水、W1:拔节期和开花期各灌水1次)以及3个施氮副处理(N0:0 kg hm^(–2)、N180:180 kg hm^(–2)和N300:300 kg hm^(–2))。结果表明:与W0处理相比,W1抑制根长密度的增加,但增加根系平均直径,提高0~20 cm土层根表面积和根干重密度,显著提高根系活力4.98%~22.7%,降低根冠比1.47%~11.25%;2年平均小麦产量、氮素吸收效率和氮肥偏生产力分别提高15.50%、13.40%和14.91%。施氮促进根系生长,与不施氮处理相比,施氮显著提高根系平均直径、根长密度、根表面积、根干重密度和根系活力,降低根冠比。其中N180更有利于根系生长,提高冬小麦根系各形态指标和根系活力,与N300相比,2年平均产量提高2.53%,而氮素吸收效率和氮肥农学效率分别显著提高44.51%和39.37%。相关分析表明,拔节期至开花期根干重密度与产量、氮利用率呈显著正相关关系;根冠比与产量呈显著负相关关系,与氮利用率呈正相关关系。因此,合理的灌水和施氮能够优化根系形态及分布,提高根系活力,协调根冠干物质分配,提高产量和氮利用率。在冬小麦生产中拔节和开花期各灌水1次结合180 kg hm^(–2)施氮量有利于促进产量和氮素利用效率协同提高。

摘要：通过比较293T细胞的接种密度、质粒DNA的量以及CO2浓度对磷酸钙转染方法的影响,确定最佳的转染条件.以各单因素试验的最适条件为依据,设计三因素三水平的正交试验.结果表明,磷酸钙介导质粒DNA转染,当293T细胞的接种密度为5×105/mL、质粒DNA的量为30μg、细胞培养环境CO2浓度为3%时,转染效果最佳.

摘要：2005年是中国承诺碳减排目标的基准年份,因而也是中国城市碳减排战略制定和近中期低碳转型的基准年份和对照年份。中国城市2005年CO_2排放数据的一致性、全面性和精准性对于中国所有城市和每个具体城市的目标考核和评估都有重要意义。基于中国高空间分辨率网格数据(CHRED 2.0)、城市层面统计数据以及大量现场调研和走访,建立2005年中国城市CO_2排放数据集,包括工业能源排放、工业过程排放、农业排放、服务业排放、城镇生活排放、农村生活排放、交通排放7个部门的直接排放数据和间接排放数据。该数据集的建立汇总了86名研究人员的工作成果,在企业、城市不同行业与部门、城市工业和城市总化石能源等不同层面进行了大量的交叉验证和数据分析,有效保障了数据的精确性和准确性。结果显示,2005年中国城市碳排放呈现出较大的体量差异和空间格局差异。排放前10的城市几乎比排放后10的城市的排放量高出两个数量级。高排放城市基本都是城市群的核心城市。东部城市直接排放占全国直接排放比例最高,达到44.59%,其次是西部城市21.76%,中部城市22.70%,东北城市10.95%。
