多层弹性体空间一般问题的解析解

本文利用广义柔度矩阵递推法,成功地导出了多层半无限弹性体空间一般问题,在任意荷载作用和两种层间接触条件下的通解.对于这个通解,不管弹性体的层数为多少,最后均不需再解任何联立方程.作为应用,文末计算了地基位移和应力问题实例.     

离散大系统的多级控制

本文使用反馈控制和广义逆矩阵研究离散大系统的多级控制问题,即在局部控制器上加所谓“校正”控制器,达到中性关联作用,使整个系统的性能指标为极小,且得到较小的性能指标偏差的上界。     

条件不完全确定的发散思维型数学问题

“在条件A之下,会产生哪些、什么样的结果B”的问题,就是发散思维型的问题。若其中的条件A带有某种不确定成份,这就构成一种“条件不完全确定的发散思维型数学问题”。这种问题求解过程中的思维活动,有许多特点,对于培养学生的创造性思维有相当高的教育价值。本文以实例为基础对此做了讨论。     

Methodological foundations of systems methodologies

In social systems science generally, and in management science particularly, recent developments in the variety of types of specific problem-solving methodologies (under the rubric of hard and soft systems approaches) have given an impetus to a line of inquiry, as well as debate on the nature of those methodologies. On the one hand, there has been the view that what we are witnessing is a form of Kuhnian crisis. On the other hand, a complementarist view of developments has been argued and a contingency approach proposed. But one thing has been common among the competing views: a belief that the prospects for further advances in the design and application of those methodologies, and in resolving the current controversies, lie in serious attempts to reconsider and clarify the underlying metatheoretical assumptions and concerns. This paper is an attempt to contribute to such an endeavor. A brief exposition of three methodological foundations (namely, empiricism, hermeneutics, and critique) is made, not only with the purpose of highlighting the nature as well as the limits of their epistemological and ethical claims, but also as a basis for illuminating both the nature of contemporary work on systems inquiry, design, and problem solving and the ongoing debate on what constitutes appropriate criteria for choice of specific methodologies.     

关于最大功原理的应用条件

本文从热力学第二定律的基本原理出发,概要地总结了论证“最大功原理”的方法,进而讨论了热力学中的一些基本问题。其基本思想是:分析热力学问题切不可忘了环境。由此得出了某些有意义的结论,澄清了在学习热力学过程中人们常产生的一些疑惑。
