In this study, first, the swimming abilities of the various swimmers involving small fishes, dolphins, whales and a manmade submarine for reference were rearranged in a logarithmic chart and the subject of the problem was settled quantitatively. Then, measurements of drag force of some fishes by a towing type instrument with strain guage and observations of the swimming motion of fishes by a high speed camera were carried out in the water channel of laboratory. According to the experimental results, there is no evidence of that the skin friction of fish is smaller than that of the solid boundary of axi-symmetrical body in the experimental range of Reynolds number between 5X10\u2074 and 5X10\u2075. And it was found that swimming speed of fishes is proportional to the body length and the oscillating frequency of the tail fin. Then, a new dimensionless number u/(f\uff65\u2113) was introduced as a swimming number. In the present observations, the swimming numbers of fish of three species were coincident each other at the value of 0.6, and this value also agreed with other species of a previous investigation.", "subitem_description_type": "Other"}, {"subitem_description": "\u7d00\u8981\u8ad6\u6587", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "\u7409\u7403\u5927\u5b66\u7406\u5de5\u5b66\u90e8"}, {"subitem_1522300295150": "en", "subitem_1522300316516": "Science and Engineering Division, University of the Ryukyus"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "jpn"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/27574"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0387-429X"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN00250785"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "\u7409\u7403\u5927\u5b66\u7406\u5de5\u5b66\u90e8\u7d00\u8981. \u5de5\u5b66\u7bc7"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "Bulletin of Science \u0026 Engineering Division, University of the Ryukyus.
