刍议体育课教学与德育渗透

本文作者认为,学校体育是一种特殊的学校教育活动,对体育教师来说,更需要从意志品质、自信心、团结协作、竞争意识、民族自豪感等方面加强学生的德育教学工作。     

静力触探（CPT）在自升式钻井船插桩分析中的应用

CPT测试作为岩土工程勘察中一项重要的原位测试技术,因其能在现场直接、连续、快捷地对岩土层的工程特性参数进行测试,并且避免了取样和室内试验对土样所造成的扰动等影响,故在国外及国内陆地岩土工程勘察领域已得到广泛应用。以南海某井场海底浅层土质工程地质特性的资料为基础,借鉴国内外CPT解释技术的经验,对海洋石油941号钻井船在南海某井场插桩深度进行了分析。     

花椒挥发油与其主要成分经皮促透作用的比较研究

研究目的：比较花椒挥发油与其主要成分作为经皮促透剂的皮肤细胞毒性,对系列不同油水分配系数药物促透作用特征及其作用机制。 创新要点：选择系列不同油水分配系数中药活性成分简化并表征中药制剂中复杂有效成分,对比研究花椒挥发油与其主要成分的经皮促透作用特征差异。 研究方法：利用表皮角质形成细胞（HaCaT）和真皮成纤维细胞（CCC-．ESF-1）测定其皮肤细胞毒性,选择系列不同油水分配系数中药活性成分作为模型药物测定花椒挥发油与其主要成分的经皮促透作用特征差异,并在此基础上采用傅利叶变换红外光谱（FTIR）等研究其促透作用机制。 重要结论：花椒挥发油相对于其单一组成成分具有更好的经皮促透效果。     

基于WebGoat的渗透测试教学平台开发与应用

当前信息安全形势下,大部分高校开设了网络安全课程,其中渗透测试技术的学习举足轻重。文章分析了各类常用的渗透测试工具,并着重对Web Goat这一开源的渗透测试平台进行研究。从课程改进和关键界面汉化这两部分着手,使Web Goat能更好地应用于实践教学,让学生在实践操作中更高效地学习掌握相关技术。     

Measuring Patterns of Self-Disclosure in Intercultural Friendship: Adjusting Differential Item Functioning Using Multiple-Indicators,Multiple-Causes Models

This study examined how friendship types, levels of friendship, and cultural backgrounds affected breadth of self-disclosure (BSD). BSD was measured with six self-disclosure topic items—in which higher scores indicated greater willingness to engage in conversations about various topics—from three groups with varying experiences with intercultural friendships. Confirmatory factor analysis was used with Multiple-Indicators, Multiple-Causes models to control for the influence of differential item functioning (DIF, groups responding differently to particular items). Findings in this study found significant evidence of DIF. These findings highlight the complex role of cultural backgrounds in the social penetration processes in intercultural friendships.     

Ammonium oxalate treatment: Evaluation by μ-Raman mapping of the penetration depth in different plasters

This study is focused on the evaluation by μRaman mapping of the penetration depth achieved by ammonium oxalate treatment in different plaster specimens, a hot issue in the conservation field. The role of the carbonatic aggregate particles and the influence of the different variables of the treatment on the penetration depth and on the distribution of the newly-formed phase (whewellite) have been ascertained. Based on the results of μRaman mapping, analyses with Field Emission Scanning Electron Microscopy have been carried out in order to observe the whewellite crystals and the carbonatic aggregate particles involved in the reaction with ammonium oxalate.     

圆锥动力触探试验机理及其在地勘中的应用

动力触探具有设备简单、测试方便,精度较好、工效较高、适应性广等优点。在现场检测中,动力触探试验不仅可以确定基床表层土的承载力,还能测定某一深度基床土的强度,掌握基床土、地基土承载力沿深度和线路纵向变化,因此在工程实践中有着广泛的应用。     

Identifying Temporary and Permanent Gaps in Universal Service

This article examines the nature of the gap in household telephone penetration among Whites, Blacks, and Hispanics. By analyzing historic and current penetration levels of the radio, television, and telephone, it suggests that most information technology gaps are amalgamations of smaller socioeconomic trends and can be discerned and reduced only with careful historical analysis of both technology choices and living patterns. It proposes localized universal service strategies, since the penetration gaps are affected by a complex array of factors more particular to localities than to the country as a whole and as such must be investigated with rigor and caution if progress toward the elimination of penetration gaps is to occur.     

西充方言“轻声、儿化”调值中平现象研究

西充方言属于入声独立区,中古入声字独立一调,调值中平(33);但音系中的中平调不仅仅只表示中古入声字的调值,还出现于轻声、儿化音以及叠音词的次音节上,这便造成了调类和调值的错位。文章认为,这样的错位,首先源于儿化等语法层面因素的渗透,渐渐导致语音的弱化;而其调值与入声的趋同,则源自音系内部的整化原则的系统整合。
