西安事变前后中共对蒋政策之嬗变

以1936年下半年以来国共两党接触的相关文献和档案为基础,从更宽的视野中去追寻形成西安事变最终解决条件的若干历史细节,并由此得出三个结论:其一,事变解决的具体条件在事变发生之前即已被双方提及;其二,突发的西安事变使蒋氏在坚持改编红军的强硬前提下放弃了极端强硬的一些条件,而回到了事变前曾经提出过的一些框架之中;其三,中共在西安事变初期态度强硬,但最终却让步,这与蒋氏的强硬不无关系,蒋在事变中并非完全处于被动。     

果胶溶液粘度的研究

本文研究了浓度、温度、酸度、Ｃａ２＋、糖等因素对果胶溶液粘度的影响，在酸度为０．９ｇＨＣｌ／１０Ｏｍｌ下来胶容液的粘度最低、而Ｃａ２＋，糖在研究的范围内对果胶溶液粘度的影响不大。

Decision Support Systems (DSS) development using a model of user inquiry types: Methodological proposals and a case study

A study of the DSS implementation area reveals an increased emphasis on methodologies for DSS development. As the DSS field matures, a larger number of methodological options are becoming available to the DSS developer. Existing methodologies have adopted various methods for performing the important task of DSS requirements analysis and specification. In envisaging a hierarchy of requirements analysis methods, a method for improved requirements analysis is proposed to remedy observed deficiencies within it. This method is based on a view of generic types of inquiries or solicitations made by the DSS user during decision-making. This formalism constitutes the basis of a proposed DSS development methodology that offers several benefits to DSS development. The intended benefits include a sharper and more focused requirements analysis to improve the DSS development process. This paper describes the model and methodology, alongside details of a real-world example of their use in developing a Marketing Decision Support System (MKDSS) for the support of marketing decision-making.
