Studies on Han Wooden Strips excavated at Xuan-quan-zhi Dun-huang in 1991-92

1)我们编制了《居延汉简索引》，其中包括：（A）地名，（B）人名，（C）官衔，（D）文章，（E）所有汉字都写在汉简上。这是我们从1990年到今年的国际科学研究计划的结果。2）调查人员之一的桃山明发现了一个汉族习俗，当他们在纸条上写一些数字时，他们会在纸条的右边刻上代表数字的刻痕。这些刻痕的目的是为了保护数字不被非法改变。这种智慧似乎与中世纪的理货相同。3）调查人员，宇井正雄、吉村正之和助理调查员门田晃参观了内蒙古额森沟地区的遗址，那里是奥雷尔·斯坦因、福尔克·伯格曼和中国考古学家发掘的汉条遗址。在他们的西方学者考察之后，除了NHK电视台的“丝绸之路”节目组之外，没有外国人参观过那里。他们参观了汉代甲克厚馆的A8遗址，确认了出土的地方。4）《楚辞汉仁版》在中国出版，经过22年的等待，但照片的清晰度并不好，当我看到他们的原始印刷品时，它是相当清晰的，并期望书籍。这取决于不熟练的出版技术。我请中国出版商在日本制作印刷版，但由于经济条件限制，经过长时间的谈判，最终未能成功，这对学者来说是一个巨大的损失。

1) We published an index named "Index of Han Wooden Strips found at Ju-yan in 1930-31 and 1973-74".It includes those indexes as follows ; (A) Names of place, (B) Names of person, (C) Official titles, (D) Articles, (E) All charactors written on Han Strips.This is a result of our International Scientific Research Programs since 1990 to this year, supported by the Ministry of Education, Science, Sports and Culture.2) Momiyama Akira, one of investigator, found a Han custom that, when they write some figures on the strips, they cut notches on the right side of strips which means the figure.The aim of these notches are to protect the numbers from illegal change.This wisdom seems same idea of tally in the Middle Ages.3) Investigators, Ukai Masao, Yoshimura Masayuki and assistant investigator Kadota Akira visited the sites of Edsen-gol region, Inner Mongolia, where Han strips excavated by Aurel Stein, Folke Bergman and Chinese archaeologist.And after their explorations of Western scholars, there were no foreigners visited there except the NHK television team of "Silk Road".They visited A8 site where colled Chia-ek-hou-kuan in Han time and confirmed the exeavated places, also, visited the Khara-khoto city site where was Jyn-yan in Han times.4) "Plates of Chu-yan-han-jen" published in China after 22 years wait al last.But, the clearness of photographs are not good.When I saw their original prints, it was rather clear, and had expects for books.It depends on unskillful tecnique of publication.I asked Chinese publisher to make plates for printing in Japan, but after long negotiations it lasts unsuccessed, because of financial condition.It is a great loss for scholars.
