and determining the adaptive storage format corresponding to each text archive based on the compatible storage format set, the stable consistent storage format set and the typesetting consistent storage format set corresponding to each text archive.
10. An electronic archive management system according to claim 9, characterized by: the specific determination of the adaptive storage format corresponding to each text archive is as follows:
comparing a compatible storage format set, a stable consistent storage format set and a typesetting consistent storage format set corresponding to each text archive, wherein if a certain consistent storage format corresponding to a certain text archive appears in the sets, the text archive is used as a common text archive, otherwise, the text archive is used as a special text archive;
for the common text archives, the consistent storage formats appearing in the sets are used as the adaptive storage formats corresponding to the common text archives;
for the special text archives, classifying the same storage formats in the compatible storage format set, the stable consistent storage format set and the typesetting consistent storage format set corresponding to the special text archives, and counting the occurrence frequency corresponding to each consistent storage format and the related set type and the consistency corresponding to each occurrence;
