The two-dimensional Riemann problem of simplifed Euler equation is discussed, in which initial value contains two different constant states that are separated by a smooth curve. This problem is a natural description of realistic phenomena, but it is hard to study by conventional idea. So a new approach is proposed. Some new properties about two-dimensional rarefaction wave, shock wave and intermediate state of solutions are disclosed.

The paper presents a flexible and effective method of development of negotiating agents. A strategy specification, which is specified by a state chart and defeasible rules, can be dynamically inserted into an agent shell incorporating a state chart interpreter and a defeasible logic inference engine, in order to yield a desirable agent. The set of desirable criteria and rules is required to be justified with different context of the application. Key words automatic negotiation - intelligence agent - defeasible logic - state chart CLC number TP 391 Foundation item: Supported by the National Natural Science Foundation of China (60173051)Biography: WEI Ding-guo (1964-), male, Associate professor, research direction: computer network protocal etc.

Ray matrix methods are used to study a paraxial Fourier transforming system which contains nonsymmetric optical elements. Two equalization conditions of Fourier transform are drived: matrix elements criteria and lens law, which may be used to distinguish a Fourier system and to determine Fourier trams-forming plane, Computing formulas for Fraunhofer diffraction region, Fourier transforming region and physical focus-depth region are *** image formation is given. As applying examples, two nonsymmetric systems are studied.

从新制度经济学的视角考察,我国教师管理制度设计存在着诸多问题,主要表现为:重教师"道德人"假设而轻教师"经济人"假设;重视教师管理的正式制度而忽视非正式制度;重视教师管理制度的约束功能而忽视激励功能;重视政府、学校对教师的管理而忽视家长的参与等。基于对以上问题的分析,本文指出教师管理变革的方向应包括:承认教师自利行为的正当性;充分利用教师管理的非正式制度;强化教师管理制度的激励功能;扩大家长参与教师管理的权力等。
