儒家"诚信"特色及其现代转化

儒家"诚信"作为具有中国特色的古典伦理形态,与现代"信用"有许多本质差异。要实现其现代转化,必须达到:由适用于"熟人"社会的特定伦理,转变为适用于"陌生人"社会的普遍伦理;由一般人伦伦理,引入经济伦理;由主观"自诚"模式,转变为契约"合意"模式;由从属于封建礼教的次要道德义务,转变为从属于"社会公正"的道德义务,并进而提升为反映现代人本质的基本道德义务。为达此转化,需要创设诸如完善市场机制、推行宪政民主、培养契约文明观念等社会文化条件。这将是一个艰难漫长的自然历史进程。     

Coupled lubrication and Stokes flow finite elements

A method is developed for performing a local reduction of the governing physics for fluid problems with domains that contain a combination of narrow and non‐narrow regions, and the computational accuracy and performance of the method are measured. In the narrow regions of the domain, where the fluid is assumed to have no inertia and the domain height and curvature are assumed small, lubrication, or Reynolds, theory is used locally to reduce the two‐dimensional Navier–Stokes equations to the one‐dimensional Reynolds equation while retaining a high degree of accuracy in the overall solution. The Reynolds equation is coupled to the governing momentum and mass equations of the non‐narrow region with boundary conditions on the mass and momentum flux. The localized reduction technique, termed ‘stitching,’ is demonstrated on Stokes flow for various geometries of the hydrodynamic journal bearing—a non‐trivial test problem for which a known analytical solution is available. The computational advantage of the coupled Stokes–Reynolds method is illustrated on an industrially applicable fully‐flooded deformable‐roll coating example. The examples in this paper are limited to two‐dimensional Stokes flow, but extension to three‐dimensional and Navier–Stokes flow is possible. Copyright © 2003 John Wiley & Sons, Ltd.

氢原子的固有电偶极矩

用经典力学和双波量子力学计算了氢原子的固有电偶极矩。双波量子理论算得的结果在经典极限下与经典力学的结果一致。普通量子力学对氢原子Stark效应中表现出来的电偶极矩难以做出很好的解释，因为一个波函数描述的是系综而不是单个粒子。经典力学和双波量子力学可描述单个粒子的行为，对永久电偶极矩的计算和解释显得自然而合理。

概化理论在语言测试新进展中的应用

概化理论是一种发展较晚但功能全面的现代测试理论，能有效地设计、分析和评估测试项目。直到上个世纪八九十年代，Robert Brennan等人开发了GENOVA等一系列应用软件后，概化理论才在心理和教育测量领域的研究中逐渐受到重视，此后，运用概化理论研究实际问题的项目也逐渐多了起来。概化理论与项目反应理论属于不同的理论范畴，它们的基本假设也有很大的差别。     

区别于计划经济的新型劳动关系研究综述

1989年之后,新型劳动关系逐渐引起人们的关注,而相关的研究也随之方兴未艾。新型劳动关系的研究背景与意义、内涵与特征、建立条件与机制建设、基本评价与发展思路等问题得到了比较深入的探讨。这些研究的特点与不足需要被客观地加以检视。     

课程实施研究理论综述

课程实施是伴随着课程改革的不断深入而出现的一个重要的研究领域。课程实施是课程改革中的一个关键环节,课程改革的成败与否关键取决于课程实施。文章将近年来国内外关于课程实施的一些研究成果进行了理论归纳,以期为我国课程改革寻找理论支撑。     

Stability analysis of abnormal multiplication of plankton using parameter identification technique

This paper presents the mathematical approach for the abnormal multiplication of plankton. An abnormal multiplication can be expressed as an unstable problem and the stability of the system is investigated by introducing eigenvalues of a mathematical equation. The stability of the system can be judged by an eigenvalue based on the Lyapunov's stability theory. In this paper, the Arnoldi‐QR method is used to obtain eigenvalues and eigenvectors of the system. The mode superposition method is employed to create spatial distribution needed to analyse the stability. To obtain the objective eigenvalue, the parameter identification technique is employed. The finite element method is used for the discretization in space. Lake Kasumigaura, which is located in Ibaraki Prefecture in Japan, is selected and actual data in 1975, 1976, 1991 and 2000 are used in order to investigate the stability of the specified lake in Japan.
