云南省的单殖吸虫——Ⅰ.滇池及其邻近湖泊的单殖吸虫
骆永德,
动物学研究 , 1981,
Abstract: 1964年6月,作者等对云南昆明的滇池及其邻近的抚仙湖、星云湖等进行了鱼类单殖吸虫的初步调查。此后又补采了若干标本,先后检查了26种鱼类,每种1—20余尾。其中除白鲢、云南鲴、黄(鱼幼)鱼、鳜、长刺鳑鲏、大刺鳑鲏及乌鳢等7种鱼类未查到单殖吸虫寄生外,在19种鱼上发现有45种单殖吸虫,其中包括一新属及7新种。所有正模及副模标本,均分别保存于昆明师院及华东师大生物系。

Abstract: The tegumentary ultrastructure of Cyathocotyle oricntalis has been described. Scanning electron microscopy shows clustered spines, ciliated papilla and non-ciliated pit-like papilla on the tegumental surface. The tegument of the holdfast is elevated into microvilli. In the transmission electron the tegument consists of a surface syncytium connected by protoplasmic strands to the cell bodies which lay below the peripheral musulature. Two types (T-1, T-2) of secretory bodies are presented in the syncytium and synthesized in the same tegumental cells. The mitochondria cells are found among the tegumental cells. The holdfast surface consists of an outer membrane elevated into microvilli and inner, fibrous basement membrane perforated by the apertures of the common ducts from the secretory cells. TEM also reveals that nonciliated pit-like papilla is glandular papilla. The tegumental ultrastructure of adult cultivated in vitro has an abnormal appearance and contains areas of vacuolation. The function of some important structures and usefulness of ultrastructural techniques to assess cultivation methods has been discussed.

矿渣微粉对水泥耐久性能影响的研究
Influence of Ground Slag on Durability of Cement

Abstract: 矿渣微粉具有一定的水化活性,掺入水泥浆体后能够明显提高水泥抗化学侵蚀性能,抗干缩,抗碳化,抗冻性等耐久性能,提高幅度基本可以达到10%左右;利用SEM,TG-DTA,XRD,压汞孔分析等方法对水泥水化物进行分析,结果表明:矿渣微粉能够吸收水泥水化产物Ca(OH)2生成C-S-H凝胶,导致降低孔径,优化孔结构,从而提高水泥石的密实度,从而改善水泥的各项性能。
Experiment of cement with ground slag shows that ground slag can improve the properties of ce-ment such as coefficient of resistance to chemical corrosion, dry shrinkage, and carbonation coef-ficient, freezing and thawing resistance by 10%. The microstructure-analysis by using SEM, TG- DTA, XRD and MIP shows that the ground slag can absorb the productions of hydrating cement: Ca(OH)2, and C-S-H gel is formed, which can refine the distribution of pore structure and increase the density of cement-stone, therefore improving the durability.

Abstract:
技术创新一直以来被认为是提高能源使用效率,降低能源消费的重要因素,但是国外就技术创新对能源消费影响的悖论一直以来颇受关注,本文根据中国的省际数据分析,用技术创新的产出和投入不同指标,分析中国能源消费效率技术悖论,即技术创新对能源消费影响的“反弹效应”。
Technological innovation is known as an important factor to improve the energy use efficiency and reduce the energy consumption on one hand. On the other hand, technological innovation is also well known as a paradox to energy consumption. Based on the provincial data in China, this paper will analyse the paradox of technology to energy consumption using different technological innovation input and output index, which is also called the rebound effect of technological innova-tion to energy consumption.
国有股与政府董事对银行业绩的影响
The Effect of State Ownership and Government-Affiliated Board Members on the Performance of Banks in China
 [PDF]


Finance (FIN) , 2015, DOI: 10.12677/FIN.2015.54008
Abstract:
以2004年到2013年30家银行的数据作为样本,分析国有股和政府董事对银行资产收益率、不良贷款率和收入费用率的影响。结果显示,国有股比例越高,或政府董事比例越高,对经营业绩负面的影响越明显。这与政府重视社会利益和政治利益的假说一致。过去十年中政府介入对不良贷款率所代表的银行稳健性明显地产生了不利影响。减少政府干预,发挥市场机制的调节作用有利于建设稳健的银行体系。
Using the data of 30 Chinese banks during the period of 2004–2013 as a sample, we analyze the im-pacts of state ownership and government-affiliated board members on bank’s return on assets, non-performed loan rates and cost-income rates. We find that the higher state-owned stock rate and more government-affiliated members make bank performance worse. The result is consistent with the hypotheses of “development view” or “politic view” of government. In the past decade govern-ment’s intervention made negative effect on banks’ soundness measured by NPL rate. The findings suggest that the government has to give up the intervention in order for a more effective and sound banking system.
?挣扎在寒夜中的职业女性――曾树生形象的再认识

天津大学学报(社会科学版) , 1999,
Abstract: ?从新的视角阐释了巴金《寒夜》中曾树生形象在现代文学史上的意义。曾树生是旧中国职业女性的一个典型,通过对她的生活和命运的展示,真实地反映了20世纪中叶半封建半殖民地社会一个普通职业女性的生存状况。曾树生形象是“五四”新女性形象的丰富和发展,她在精神上经济上具有独立意识。这一形象蕴涵着巴金对女性的生存意义及出路的探索。
