应用皮肤光毒性实验仪进行化妆品皮肤光毒性试验的研究

[目的]探讨应用皮肤光毒性实验仪进行化妆品皮肤光毒性试验的试验条件和阳性对照物8-MOP的合适试验浓度。[方法]观测皮肤光毒性实验仪的UVA光强度与开机时间的关系,并根据测得的光强度平均值计算得出光毒性试验所需的照射时间;用不同浓度的8-MOP进行试验,排除8-MOP的原发性刺激作用,选择适宜的应用浓度进行皮肤光毒性试验;对两个防晒粉底按所选仪器条件进行试验。[结果]照射开始后2-100m in,UVA光强度稳定在4.3-4.4 mW/cm^2,平均值为4.4 mW/cm^2,故试验时的照射时间为38m in;用皮肤光毒性实验仪进行光毒性试验,0.05%8-MOP能引起豚鼠皮肤明显光毒性反应并且不引起原发性刺激反应;相同试验条件下未见两种防晒粉底引起豚鼠皮肤显著光毒性反应。[结论]用皮肤光毒性实验仪进行化妆品皮肤光毒性试验可行、有效。     

冲压同步工程在汽车开发中的运用

冲压同步工程分析（SE）,即运用DFM（Design for Manufacturability）的方法及辅以先进的CAE技术在整车开发的过程中对整车零件进行冲压成形性能评价,在满足制造要求和零件设计之间找到最优结合点,有效降低设计风险及设计成本。文章简要介绍了冲压SE工作的一般内容、目标以及在SGMW某新项目中的应用情况。     

Application of CVAM-based management accounting in mobile telecommunication enterprises

CVAM-based management accounting emphasizes that enterprises should make efforts not only to provide goods or service to customers but also to create value for customers.

企业价值评估贴现模型的比较分析

贴现模型是企业价值评估中应用较为普遍的模型,但在我国实践中使用贴现模型存在很多问题。本文利用自由现金流量贴现法、调整现值法、经济利润贴现法三种常用的方法,探讨贴现模型不同参数指标的原理、使用原则、使用条件及在我国实践中的适应性,希望讨论能够为企业价值评估实务提供指导和帮助。     

The impact of foreign direct investment and trade on economic growth Taking China, Korea, Malaysia, Philippines ＆ Thailand for example

In this study the authors make efforts to survey the impact of foreign direct investment and trade on the economic growth of five East Asian countries, China, Korea, Malaysia, Philippines and Thailand. Using an augmented production function （APF） growth model, the authors apply panel data Method and data span is from1980 to 2006. The required data are extracted from World Development Indicator 2008. The result shows that a co-integration relationship between growth and its determinants in the APF model is supported. Firstly, the study shows that with the increasing the inflow of foreign direct investment, positive impact on growth in Thailand, Korea and China is proved. However, this impact is negative in Philippine and Malaysia. Also the impact of trade on economic growth has the same result with FDI impact in sign. Further, the impact of labor force on growth is not significant in these countries and the effect of gross fixed capital on growth is positive and has a very high impact on selected countries.     

《说文解字》八部字研究（上）

许慎在《说文解字》当中首创的汉字部首说是我国文字学研究的一个伟大创造,但他的部首说及其归部原则并不是无懈可击的真理。比如,《说文解字.八部》就是一个值得商榷的典型。我们充分利用目前所能见到的甲古文、金文、战国文字等文字形体重新审视了《说文解字.八部》诸字,发现许慎的八部归部存在一些不可忽视的偏差。即《说文解字.八部》内只有＂分＂,＂尒＂,＂曾＂,＂尚＂,＂＂,＂詹＂等字本义与八字本义联系紧密,可以入八部。     

美国人何以养老——美国养老保险体系与可持续研究

美国的养老保险体系是由国家通过税收筹资的基本养老基金、企业建立的以401(k)计划和个人退休帐户(IRAs)为主的职业养老金计划以及相当完善的商业养老保险共同构成的三支柱式养老保险体系。通过具体分析美国国家基本养老和企业职业养老基金的构成、收入来源、支出水平以及可持续能力,说明美国养老保险体系是一个制度完善、可持续能力较强的养老保险范例,值得我国借鉴。
