??丁家立汉学思想初探

天津大学学报(社会科学版) , 2008,
Abstract: ?丁家立的汉学研究主要集中在孔子的儒家思想上,因为孔子的哲学思想一定程度上契合了其所信奉的新教的理性主义和现实主义。他比较了中国语言文字的优缺点,建议发展表音文字与普及白话文,并在中高等教育中使用英语教学。通过对开封犹太人的研究,他劝告西方传教士要警惕中国文化异乎寻常的同化力。从现实主义立场出发,他认为西方人应当对中国文化采取一定的妥协和宽容,把西方近代文化与中国传统文化中的某些要素结合起来,使其在中国发展繁荣。

Abstract:
使用王才康等人翻译修订的一般自我效能感量表(GSES),分别对250名普通高校大学生和230名高职院校大学生进行调查。分析普通高等院校不同类型学生自我效能感的差异以及高职院校不同类型学生自我效能感的差异。结果表明:高职院校学生自我效能感均分32.55,高于全国常摸水平,与普通大学有一定差距,但没有显著性差异。不同性别、不同年级、不同兼职状况、是否担任班干、不同学科及奖学金获得状况不同的高职大学生自我效能感水平不存在显著差异;高职院校学生自我效能感水平在生源地、是否为独生子女以及是否参加过社团活动方面存在显著差异;普通大学学生自我效能感水平在生源地上存在显著差异。本研究针对影响学生自我效能感的差异因素提出建设性的意见,为高校的学生工作的良好开展提供可行性建议。
A total of 250 college students and 230 higher vocational college students were investigated by using the General Self-Efficacy Scale (GSES) revised by Wang Caikang et al. The differences of self-efficacy among different types of students in ordinary institutions of higher learning and the differences of self-efficacy among different types of students in higher vocational colleges. The re-sults showed that the average score of self-efficacy was 32.55, which was higher than that of the national average, and there was no significant difference. There were no significant differences in the level of self-efficacy among higher vocational college students with different gender, different grades, different part-time positions, different classes and different scholarships. The level of stu-dents’ self-efficacy was higher in the students’ singleton children and whether they participated in community activities. There were significant differences in students’ self-efficacy level among the college students. This study provides constructive suggestions on the factors that affect students’ self-efficacy, and provides feasible suggestions for the development of students’ work.

Abstract: 摘要 提出一种基于特征筛选和二级分类的建筑提取算法。该算法首先对极化SAR数据进行精致Lee滤波,获取多维极化特征和纹理特征构成原始特征集;然后将随机森林作为初级分类器评估各特征的重要性,依据重要性排名进行特征筛选;最后通过支持向量机对特征子集进行次级分类,并用邻域投票法将两级分类结果融合。AIRSAR极化数据实验结果表明,本算法可有效提高极化SAR建筑提取准确率。

Abstract:
大连滨海湿地资源丰富,湿地类型多样,且地处于东北亚地区鸟类迁徙的重要通道上,生物物种多样,种群复杂,在环渤海区域海洋经济发展中乃至东北地区经济发展中占有极为重要的位置。是国际上具有重要价值的湿地。本研究在调查大连市滨海湿地现状的基础上,从湿地面积,湿地生物多样性,以及湿地污染等多方面对大连地区滨海湿地进行较为全面的分析,并提出了针对大连滨海湿地现状提出了合理的管理保护建议。为以后大连地区滨海湿地保护提供科学的依据和有力的理论指导。
Dalian coastal wetlands are rich in resources, with various types of coastal wetlands located in the important bird migration routes in the Northeast of Asia. They have abundant biological species diversity and complex species, occupy a very important position in the marine economy development of Bohai region and the economic development in the Northeast of China, and are important valuable wetlands in the world. Based on the investigation of status of Dalian coastal wetlands, the paper presents a comprehensive analysis from the following points: the area of the Dalian coastal wetland, wetland bio-diversities, as well as the pollution of wetlands. It also puts forward reasonable suggestion about wetland protection and management, which provides a scientific basis and theoretical instruction for Dalian coastal wetlands protection in future.

遥感技术与应用 , 1989,
Abstract: 洞庭湖遥感基础试验是国家“七五”攻关项目的一个子课题。洞庭湖是我国第二大淡水湖,又是重要的集水、蓄洪调节湖泊。它的北部与长江连接,南、西部与湘江、资水、沅水、澧水相通。对调节华中地区气候、维护生态平衡,汛期调节洪水,消减洪峰、保护长江中下游人民生命财产起着不可估量的作用。洞庭湖平原同时又是我国十二个商品粮基地之一。据记载,1825年洞庭湖面积6400平方公里,如今水面仅有2651平方公里。专家统计分析:当南、东洞庭湖分别淤积达29米、26米的海拔

基本养老保险个人账户能否应对老龄化
,吴可昊 ?
期刊检索-中国人口科学 , 2003,
Abstract: 为应对人口老龄化.中国社会养老保险制度的筹资模式由现收现付制转变为部分积累制,从而在基本养老保险制度中引入了个人账户制度。然而,现行制度下的个人账户能否真正应对老龄化的挑战,值得探讨。文章以浙江省基本养老保险制度为考察对象,根据全国第五次人口普查浙江省的资料,借助保险精算理论,讨论在一定的待遇系数下,投资回报率与个人账户基金可支付年限的关系;在一定的投资回报率之下,个人账户基金可支付年限与待遇系数的关系;在不同待遇系数下,个人账户养老金月标准能否达到目标替代率
超临界流体干燥法制备TiO2/Fe2O3和TiO2/Fe2O3/SiO2复合纳米粒子及光催化性能
,李青,曹维良
复合材料学报 , 2005,
Abstract: 以TiCl4、Fe(NO3)3·9H2O和Na2SiO319H2O为原料,采用溶胶凝胶法结合超临界流体干燥法(SCFD)制备了纳米级TiO2/Fe2O3和TiO2/Fe2O3/SiO2复合光催化剂。以光催化降解苯酚对所得催化剂的催化活性进行了评价。结果表明,纳米TiO2/Fe2O3复合粒子与单组分TiO2比较,复合粒子光催化活性高于单组分的TiO2,6h苯酚降解率高达95.9%。SiO2的加入可以抑制纳米粒子粒径的长大和晶相的转变,增强TiO2纳米粒子的热稳定性。复合光催化剂中Fe2O3最佳掺入量为0.06%,SiO2最佳掺入量为10%(摩尔分数)。并用XRD、TEM和FTIR等手段进行了表征。TiO2以锐钛矿型形式存在,SiO2以无定性形式存在。比较了不同制备方法制得的TiO2/Fe2O3复合光催化剂,得出超临界干燥法制备的光催化剂具有粒径小、比表面积大、分散性好、光催化活性高等特点。采用超临界流体干燥可直接得锐钛型纳米复合光催化剂。
