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 (Na₂Si0₃9H₂0) or sodium hydroxide (NaOH) is used as the agent. However, in Okinawa it is thought that, sodium triphosphate (Na₅P₃0₁₀) 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 (NaP0₃)₆ is more effective than others used before for Shimajiri Formation soils.", "subitem_description_type": "Other"}, {"subitem_description": "紀要論文", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "琉球大学理工学部"}, {"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": "琉球大学理工学部紀要. 工学篇"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "Bulletin of Science \u0026 Engineering Division, University of the Ryukyus.
