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

1)出版了《居延出土汉简索引》，索引内容如下：(A)地名，(B)人名，(C)官衔，(D)文章，(E)所有汉字写在汉条上。这是我们从1990年到今年在文部科学文物省支持的国际科学研究计划的结果。2)调查人员之一木山明发现，当他们在汉条上写一些数字时，他们在数字的右边刻痕。这些刻痕的目的是为了保护数字不被非法改变。这一智慧似乎与中世纪的统计思想相同。3)调查人员、Ukai Masao、Yoshimura Masayuki和助理调查员Kadota Akira参观了内蒙古埃德森-果勒地区的遗址，那里是Aurel Stein、Folke Bergman和中国考古学家出土的汉带。在他们对西方学者的考察之后，除了《丝绸之路》NHK电视台的团队外，没有外国人访问过那里。他们参观了汉代考古嘉后馆的A8遗址，并确认了出土的地点4)中国时隔22年后出版的《楚延汉人图版》。但照片的清晰度并不好。当我看到它们的原版时，它相当清晰，对书籍也有期望。这取决于不熟练的出版技术。我要求中国出版商制作印版到日本印刷，但由于经济条件的原因，谈判未能成功。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.
