著名美籍华裔作家哈金的作品《等待》在英美文学界取得了巨大的成功.但是国内文学界对《等待》的研究目前仍然欠缺足够的广度和深度。本文根据艾布拉姆斯、布鲁克斯和沃伦等人的理论.尝试对《等待》进行更为深入和全面的梳理,讨论并揭示了作品的现实主义风格。本文认为,《等待》的现实主义品格代表着小说古典路线的回归.其具体体现在两个方面:真实生动的人物形象塑造、客观超然的叙事态度。 相似文献

We report an important observation that the surface conductivity of antibody layer immobilized on polylysine-coated glass
substrate decreases upon the formation of complex with their specific antigens. This change in conductivity has been observed
for both monoclonal and polyclonal antibodies. The conductance of monoclonal mouse IgG immobilized on polylysine-coated glass
substrate changed from 1.02×10−8 Ω−1 to 1.41×10−11 Ω−1 at 10 V when complex is formed due to the specific biomolecular interactions with rabbit anti-mouse IgG F(ab′)2. Similar behavior was observed when the same set up was tested in two clinical assays: (1) anti-Leishmania antigen polyclonal
antibodies taken from Kala Azar positive patient serum interacting with Leishmania promastigote antigen, and (2) anti-p21
polyclonal antibodies interacting with p21 antigen. The proposed concept can represent a new immunodiagnostic technique and
may have wide ranging applications in biosensors and nanobiotechnology too. 相似文献

Two sulfonylurea herbicides, metsulfuron methyl (Ally 20 WP) and chlorimuron ethyl (Classic 25 WP) were evaluated for their dissipation bchaviour in alluvial, coastal saline and laterite soils under laboratory incubated condition at 60% water holding capacity of soils and 30 ℃ temperature was maintained. In field study herbicides were applied twice for the control of grasses, annual and perennials broad leaves weeds and sedges in rice, wheat and soybean to find out the residual fate of both the herbicides on different matrices of respective crops after harvest. Extraction and clean up methodologies for the herbicides were standardized and subsequently analyzed by HPLC. The study revealed that the half-lives of metsulfuron methyl and chlorimuron ethyl ranged from 10.75 to 13.94 d irrespective of soils and doses applied. Field trials with rice, wheat and soybean also revealed that these two herbicides could safely be recommended for application as no residues were detected in the harvest samples. 相似文献

The changing roles and relationships of professional staff in Reference and Cataloging departments in the catalog creation process are discussed. Specific examples are given for handling classification, subject headings and cross references. The article stresses the importance of interface between the two departments in making the catalog more accessible to the users of the library. 相似文献

水上项目:三军出击 奥运会水上项目拥有41枚金牌,而中国运动员至今与之无缘。中国皮划艇队经过八年的卧薪尝胆,已经具备向欧美传统强队叫板的实力,也责无旁贷地担当起了中国水军的冲金“先锋”。其中,男子双人划艇、女子双人皮艇和四人皮艇有希望实现突破。不过今年以来,国际上皮划艇项目的竞争十分激烈,前六名的差距一般在1秒以内,因此其结果存在很大变数。此外,奥运经验的缺乏以及时差、气候、场地等客观因素也给中国队员的冲冠之路蒙上了一层薄雾。 中国赛艇队在悉尼奥运会上惨败,此次虽雄心勃勃,却在争夺奥运席位的过程中遭遇“寒流”… 相似文献
