聚乙二醇对十二烷基苯磺酸钠胶束形成和溶解性的影响

考察了不同分子量聚乙二醇对十二烷基苯磺酸钠溶液胶束形成和溶解性的影响。结果表明：聚乙二醇使十二烷基苯磺酸钠的ＣＭＣ和ＫＰ降低，在聚乙二醇浓度在０－０．１０ｍｏｌ／Ｌ，分子是为３００－６００范围内，随聚乙二醇浓度增加和分子量增大，降低程度愈大。     

电场中颗粒流量突变行为的理论判据

关于颗粒流在电场中的行为，中科院物理所作了许多实验工作，并得到一些有意义的结果，但对电场中颗粒流量突变条件未作定量研究，而该条件对实验结果分析及预测至关重要，作者用动力学方法导出颗粒流量突变的理论判据，并用该判据对的实验结果作了比较，结果基本吻合。     

基于模糊时间Petri网的网络计划模型

针对工程计划中工序作业时间的不确定性以及传统网络计划方法缺乏数学表达能力等问题 ,提出了用模糊时间Petri网 (fuzzy timingPetrinet,FTPN)表达工程计划、求取关键路径的新模型。在给出了时间模糊数、FTPN的形式化描述、FTPN触发规则及数学特性和工程计划FTPN建模规则的基础上 ,把求取工程计划的关键路径问题转化为一个基于FTPN代数方程求取特定标识问题 ,在此基础上 ,进一步计算了工程计划在约束条件下按时完工的可能性。结果表明 ,所提出的模型既能正确、直观地表达工程计划问题 ,又能形式化描述、计算工程计划关键路径问题。

Developing the methodology of TSI: From the oblique use of methods to creative design

During the last 13 years, a dialogue has been conducted in the Critical Systems literature on the subject of choice betwen methods. However, in the late 1980s and early 1990s, researchers went in two separate directions. One direction involved an exploration of the “creative design of methods.” This is when the problem situation is understood in terms of a series of systemically interrelated research questions, each of which might need to be addressed using a different method, or part of a method. A synthesis is generated that allows each individual research question to be addressed as part of a whole system of questions. The other research direction involved the development of “Total Systems Intervention” (TSI), a meta-methodology that, amongst other things, encourages the creative exploration of the problem situation prior to the choice of methods. One of the latest innovations in TSI is a theory of the “oblique” use of methods. This is the use of methods for purposes other than those they were originally designed for. However, it is argued here that all the case studies that have been subject to an “oblique” interpretation can be better explained if they are seen as examples of the creative design of methods. We can therefore bring together the two strands of research that have hitherto been pursued separately in the Critical Systems literature. it is suggested that TSI can be enhanced by an understanding of the creative design of methods because the latter allows us to explain the purposive, flexible, and responsive way in which TSI is most successfully used in practice.
