灾害史研究中的年代换算及其软件

THE TRANSFORMATION OF CALENDARS FOR RESEARCH ON THE HISTORY OF DISASTERS AND TCHD SOFTWARE

“灾害史中的年代换算（TCHD）”软件是进行年代换算的专用软件。本文研究了几种主要历法的年代换算的具体算法．介绍了该软件的结构，流程和功能．TCHD软件使灾害学和历史学等领域的研究人员摆脱了传统的朔闰表式的历法对照和检索方式，并成为灾害史工作计算机化的一部分。

The software of 'The Transformation of Calendars for the History ofDisasters (TCHD)' is a professional software for the transformation of calendars. Thispaper conducts research on the algorithm of the transformation of TCHD software.TCHD software not only frees the researchers in such fields as catastrophology,history, etc., from the traditional way to look up calendars in tables but also makes itself apart of the computerization of the work on the history of disasters.
