The Inner Clues of TaoTeChing

TaoTeChing is one of the most important classics of Chinese literature. There are inner clues in TaoTeChing. Lao-tzu found that all the visible things are produced or born by something, which means that these observable things could not be the ultimate source of the universe. The ultimate source of the universe must be invisible and has no color or sound. Lao-tzu called it the ＂Tao＂. On this basis, Lao-tzu got a series of conclusions including that the ＂Tao＂ runs spontaneously only following the law of itself and is not controlled by anything; The ＂Tao＂ is characterized by weakness and doing nothing; etc.. In this paper, we try to recreate the process of Lao-tzu＇s construction of his ideology.

出土算术文献复原的新方法:穷举法、特性分析法

数字残缺是出土算术类文献整理中的常见问题。《算数书》“大广”算题有两种在特定情况下简单有效的解决此问题的方法,即穷举法、特性分析法。穷举法,即将取值范围内所有的可选项逐一验证,直到验证完毕。其要求是:可选项必须是有限的。它在分母完整、分子缺失的情况下,简单有效,通常可以极大地缩小范围,甚至是直接得出正确答案。特性分析法是根据算题的特性,灵活地采取相应的解法。
