慢性萎缩性胃炎与正常胃活检组织RNA分布的研究

采用异硫氰酸荧光素（FITC）标记的核糖核酸酶（FITC－RNase）作为探针，结合半薄切片技术，观察了慢性萎缩性胃炎与正常胃活检组织中RNA的分布变化，结果表明：慢性萎缩性胃啖腺体细胞内RNA明显减少，分布部位与正常胃腺体细胞差异较大，这些结果于慢性萎缩性胃炎的病理诊断提供了一些依据，对进一步从分子水平上研究慢性萎缩性胃炎的病理变化及其与胃癌的关系具有一定的意义。

SCHEDULING PROBLEMS - AN OVERVIEW

There seems to be a significant gap between the theoretical and the practical aspects of scheduling problems in the job shop environment. Theoretically, scheduling systems are designed on the basis of an optimum approach to the scheduling model. However in the practice, the optimum that is built into the scheduling applications seems to face some challenges when dealing with the dynamic character of a scheduling system, for instance machine breakdown or change of orders. Scheduling systems have become quite complex in the past few years. Competitive business environments and shorter product life cycles are the imminent challenges being faced by many companies these days. These challenges push companies to anticipate a demand driven supply chain in their business environment. A demand-driven supply chain incorporates the customer view into the supply chain processes. As a consequence of this, scheduling as a core process of the demand-driven supply chain must also reflect the customer view. In addition,     

我国股票市场的价值基础及价格泡沫研究

借助剩余收益模型测定了我国股票市场1992年至2002年历年年末的市场价值基础,并探讨了股票市场价格泡沫问题.研究结果表明,尽管上市公司的盈利能力不断下降,但市场的价值基础并未出现明显下降;由于市场的不成熟,我国股票市场中的泡沫成分较多;股价指数及市盈率指标不具有价格泡沫及投资价值的判断功能.
