In this procedure, the dispersing agent is used for securing the necessary and accurate data of grain sizes. In JIS procedure-A 1204-1969, usually, sodium silicate (Na\u2082Si0\u20839H\u20820) or sodium hydroxide (NaOH) is used as the agent. However, in Okinawa it is thought that, sodium triphosphate (Na\u2085P\u20830\u2081\u2080) is more effective for the certain soils to disperse. This paper clescribes a test results of grain-size analysis using some other dispersing agents for Shimajiri Formation soils to get a suitable agent and its procedure. It is shown that sodium hexametaphosphate (NaP0\u2083)\u2086 is more effective than others used before for Shimajiri Formation soils.","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/20.500.12000/27020"}]},"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 & Engineering Division, University of the Ryukyus.
