本文以John R.塞尔和D.范德维克关于语用逻辑的研究工作为基础,构造了命题的语用逻辑的形式公理系统PF,证明了PF的三类定理:关于语用行为的定理、关于条件的语用行为的定理以及关于语用力量的定理。作者还构造了PF的语义模型,给出了系统的语义解释,并证明了系统的可靠性、一致性和完全性。本文以语用逻辑的方法,分析了人工智能语言PROLOC的语法和语义,以及语用逻辑在学习策略中的应用。最后讨论了语用逻辑的形式化和语言逻辑在认知科学中的应用等问题。作者的工作是继乔姆斯基的形式语法学、蒙太格的形式语义学之后,对语用学的基础理论语用逻辑的形式化研究所做的尝试。

Journal of Thermal Science 2010年第6期19卷 514-518页

作者： Jian-Jun LIU, Bai-Tao AN, Jie LIU and Zhan W Institute of Engineering Thermophysics, Chinese Academy of Sciences, P. O. Box 2706, Beijing 100190, China professor,phd Institute of Engineering Thermophysics Chinese Academy of Sciences Beijing China

This paper describes the improvement of leading edge film cooling effectiveness for a turbine inlet guide vane by using fan-shaped film cooling holes. The modification details are presented in comparison with the base-line configuration of cylindrical holes. Numerical simulations were carried out for the base-line and modified configurations by using CFX, in which the k-ε turbulence model and scalable wall function were chosen. Contours of adiabatic film cooling effectiveness on the blade surfaces and span-wise distributions of film cooling effectiveness downstream the rows of cooling holes interested for the different cooling configurations were compared and discussed. It is showed that with the use of fan-shaped cooling holes around the leading edge, the adiabatic film cooling effectiveness can be enhanced considerably. In comparison with the cylindrical film cooling holes, up to 40% coolant mass flow can be saved by using fan-shaped cooling holes to obtain the comparable film cooling effectiveness for the studied inlet guide vane.

To different extents and the threeaspects of sports training principle,event group training theory and specif ic event training theory,the modern theory of sports training has achieved development and gradually formed, the theory system of competitive sports together with the learnings of sports ta1ents indentificaion,sports competition,and management of copetitive sports. The researches on the training of competitive ability, the process of sports training and the social factors affecting training competition has developed in depth, with some new reseach focuses having come into being. A wide,deep involvement of modern science and technology into the development of theory and prac tice of sports training has become an importannt phenomenon and a significant tendency.

According to the characteristics of sports science research and in the light of the current development of our times, the paper discussed the important role of methodology in sports science research. While reviewing the significant progress made in China in research methods of sports science, the paper also pointed out some deficiencies in methodology and in the applicstion of specific methods. The paper expolinded that the development of sports in our country had made high demands of our times on scientific research method. It also encouraged sports scientists to make every effort to improve methodology so as to establish and develop our own sports science school in China.
