关于行政事业单位会计运用权责发生制的思考

我国现行的预算会计制度是以收付实现制为基础,随着社会主义市场经济体制的建立和完善,公共财政体制的建立和预算管理制度"三项改革"的深入,对行政事业单位会计核算的要求明显提高,必然引发会计改革,改革的核心之一就是由收付实现制向权责发生制转轨.

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.     

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.

解平行四边形板弯曲问题的二元B样条有限元法

将文献［１］以二元二次Ｂ样条函数为基底,求解矩形薄板弯曲问题的二元Ｂ样条有限元的方法推广到用于求解平行四边形板弯曲问题．结果表明：该方法系数矩阵每行的非零元仅２１个,相对于朱明权和ＣｈｕｉＣ．Ｋ．等的张量积型样条有限元方法,计算量与存贮量都大大节约．
