Research on Kanji Characters Used in Information Handling on Japanese Cultural Properties.

通过对日本文物学文献中近300万个汉字的考察，发现99.71%的汉字使用频率属于JIS（日本工业标准）X 0208-1990规定的第一级和第二级汉字字符集，99.94%的汉字使用频率属于JIS X 0212-1990规定的增补汉字字符集。而与ISO（国际标准化组织）10646-1:1993规定的通用多八位编码字符集（UCS）的比率为99.96%。尽管比例如此之高，但必须承认，在日本文物的描述中，它们仍然缺乏一些特殊的汉字，如“*”（Hazou）、“*”（Shikoro）等。

Examination over nearly 3 million characters in documents on Japanese cultural properties revealed that the 99.71% of the frequency of the usage of Kanji characters is included in the 1st and the 2nd level Kanji character set under the regulation of JIS(Japanese Industrial Standard) X 0208-1990 and the 99.94% in the addition of Supplementary Kanji character set under the regulation of JIS X 0212-1990, while the ratio with the Universal Multiple Octet Coded Character Set(UCS) under the regulation of ISO(International Organization for Standardization) 10646-1 : 1993 becomes 99.96%.In spite of such a high ratio, it must be admitted that they still lack some peculiar Kanji characters in the description of Japanese cultural objects such as "*"(Hazou), "*"(Shikoro) and so on.
