内部控制对建设项目风险评估实践研究

内部控制是确保企业稳定健康发展的不可或缺的"稳定器".本文应用内部控制框架和项目管理理论,采用问卷调查法、流程图法等方法对建设项目辨识影响财务报告可靠性的风险,采用主观评分法和层次分析法评估风险,建立了风险评估模型.     

成人学士学位授予工作的实践与思考

成人本科学士学位的授予工作是我国学位工作的重要组成部分。学位授予工作存在的诸多问题,成人教育普教化模式严重,标准不统一,缺乏灵活性,社会对学士学位获得者重视不够。提高成人学士学位授予质量,加强教学管理队伍建设,确保学士学位授予质量,完善成人学士学位授予制度,建立成人本科教育的学位授予质量与管理保障体系。     

工资差异均值分解的一种新改进

本文在评述Oaxaca、Blinder、Cotton和Neumark等学者关于"指数基准问题"(index number problem)研究之演进及其局限的基础上,提出并论证了一种更具解释力的"无歧视工资结构"新形式,以更准确地推断Oaxaca-Blinder分解中歧视的大小程度。文章在对指数基准进一步挖掘、矫正和逼近的同时,从理论抽象和现实操作两个层面优化了工资差异的均值分解,深化了对歧视的理解和刻画。     

汽柴油升级装置的工业应用

中油大港石化公司作为奥运期间北京市场高清洁油品的供应单位,积极进行装置改造,于2008年投产75万t／a汽油加氢脱硫装置和t00万t／a蜡油加氢裂化装置,实现了汽、柴油质量升级,按时完成了供应任务。从产品质量、产品结构以及添加剂消耗等方面对升级前后的情况进行了对比论述,根据升级后存在的问题提出了产品质量的改进建议     

固相萃取——液相色谱分析蔬菜中多种苯甲酰脲类昆虫生长调节剂残留量

[目的]建立一种同时测定蔬菜中多种苯甲酰脲类昆虫生长调节剂残留量的方法。[方法]样品经过乙腈提取,ENVI-18固相萃取小柱净化,以乙腈-甲酸（0.05%）为流动相,配备Symmetry C18柱、紫外检测器（258nm）的高效液相色谱仪对待测组份进行了分离和测定。[结果]空白蔬菜样品中除虫脲、灭幼脲、杀铃脲、氟铃脲、氟丙氧脲和定虫隆添加回收率分别在80.60%～100.80%,75.75%～98.91%,70.20%～98.33%,74.20%～95.00%,75.64%～95.50%和78.62%～97.30%之间,相对标准偏差（RSD,n=6）均小于10%,最低检出浓度（S/N=3）分别为0.013,0.014,0.014,0.013,0.013和0.014mg/kg。[结论]本方法操作过程简单快速,重复性好,能满足蔬菜中除虫脲、灭幼脲、杀铃脲、氟铃脲、氟丙氧脲和定虫隆残留量的检测要求。     

反相微乳液法制备EDTA-Tb掺杂SiO2粒子及其荧光特性

用反相微乳法制备了EDTA-Tb掺杂的SiO2荧光粒子.XRD、IR分析表明所得粒子为非晶态,EDTA中的羰基以双齿配位的形式与Tb3+配位,荧光粒子中存在Si-OH缺陷.荧光光谱分析表明,在277-396nm之间有一宽而强的Tb3+离子的激发谱带,240nm处的最强激发峰是由配体EDTA吸收能量,并将能量传递给Tb3+使之发出特征荧光所引起,在240nm光激发下,发射波长位于486nm(5D4-7F6)、544nm(5D4-7F5)、582nm(5D4-7F4)、620nm(5D4-7F3),掺杂的EDTA-Tb与SiO2摩尔比在1:120～1:15之间时,随着EDTA-Tb的掺杂量的增加SiO2粒子在发射波长为486nm、544nm、582nm、620nm时的最大发射光强度均呈指数增长.     

Shanghai Expo in Promotion

As an important part of the prep- aration work of World Expo Shanghai 2010,the organizers have launched a series of suc- cessful promotion campaigns in China, participating countries,BIE members' countries,etc.,as for developing aware- ness and conveying the concept of the worldwide grand events.Various methods are used in the promotion work,such as dedicating a 5.28-square-meter area at the core of the city to exhibitions,events and forums,and building a powerful and last- ing pilot example of sustainable and har- monious urban living.

More Dialogue and Further Development

In January 2008 Slovenia took over the six-month rotating Presidency of the EU Council and this is the first time since the wide EU expansion in 2004 that a new member state bears this responsibility. China is Slovenia＇s most important trading partner in Asia and in the past few years the turnover between China and Slovenia has been increasing steadily. Since 1992, China and Slovenia have maintained high-level contacts and regular dialogue. In November 2007, Slovenian Prime Minister Janez Jansa paid a visit on the state level, which was very successful and provided a new push for further strengthening of bilateral ties. This year marks the 16th anniversary of the establishment of diplomatic relations between China and Slovenia. China＇s Foreign Trade appreciated the opportunity to interview His Excellency Dr. Marjan Cencen, ambassador of the Republic of Slovenia to the People＇s Republic of China, and discuss bilateral relations of the two countries, the new business exchange, while also taking a look at relations between China and EU.
