六角螺系统的 Harmonic 指标

图G的 Harmonic指标定义为图G 中所有边uv 的权重2du＋dv 的和，用 H（G）表示；二阶Harmonic指标被定义为图G中所有二长路uvw的权重3du＋dv＋dw 的和，用2H（G）表示；其中du表示G中点u的度数。该文研究了六角螺链和六角螺系统的 Harmonic 指标，发现它们的极图不唯一。通过研究二阶 Harmonic指标，确定了六角螺链的极图，发现六角螺系统的极图是一类特定的图。并且找到一个关于Harmonic 指标的极图和二阶 Harmonic 指标的极图的关系。最后，提出一个关于 Harmonic 指标的开放新问题。

Total systems intervention and human inquiry: The search for a common ground

Total Systems Intervention (TSI) is an approach to intervening in problem situations which has much to offer where complex interacting issues need to be addressed by the complementary use of intervention methodologies. That such an approach has much in common with Action Research (AR) has been recognized, with much recent effort being devoted to the relationship between AR and Critical Systems Thinking (CST), the theoretical endeavor underpinning TSI. This paper further develops this line of debate and relates AR or Human Inquiry (HI) more directly to TSI, using an information systems intervention to enhance the study. The outcome is a demonstration of how TSI implicitly uses techniques informed from the field of Action Research, and how a more thorough synthesis of HI with TSI might serve to improve the overall intervention process.

The harmonic decomposition reconstruction for the exponential radon transform

The exponential Radon transform, a generalization of the Radon transform, is defined and studied as a mapping of function spaces. It is represented in terms of Fourier transform of its domain and range, and this leads to the harmonic decomposition reconstruction. The results are similar results of Tretiak and Metz.
