That is, round crystals, its size being about 4μ, deposit under the large amount of CaCO3 deposition, whereas crystals of tabular idiomorphic form with well developed faces grow up to 6μ in size in the period from November to December. But small crystals 0.5μ with imperfect forms appear in January, and thereafter dissolve in hibernation. Small crystals below 0.5μ develop at first after hibernation. \n3) The luster of the nacre chiefly depends upon the reflection of light on the surface and the planes of lamellae near the surface of the pearl, and is controlled by the aggregation, the particle size and the form of mineral crystals in there. \n4) The luster of the pearls which are collected during November and December shows the highest, while that of the pearls in hibernation, January to March, shows the lowest. \n5) A dissolved surface and the lamellae formed in winter below 13˚C of the water temperature have the scattering effect for light. \n6) The regular growth pattern on the nacreous surface appears to play the role as the diffraction gratings for light.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立真珠研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"National Pearl Research Laboratory","subitem_publisher_language":"en"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"pearl_k_586","subitem_relation_type_select":"Local"}}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"日本真珠振興会Archive"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://jp-pearl.com/wp-content/uploads/2018/04/houkoku00601.pdf#008","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00091717","subitem_source_identifier_type":"NCID"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Wada, Koji","creatorNameLang":"en","creatorNameType":"Personal"},{"creatorName":"和田, 浩爾","creatorNameLang":"ja","creatorNameType":"Personal"},{"creatorName":"ワダ, コウジ","creatorNameLang":"ja-Kana","creatorNameType":"Personal"}],"familyNames":[{"familyName":"Wada","familyNameLang":"en"},{"familyName":"和田","familyNameLang":"ja"},{"familyName":"ワダ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Koji","givenNameLang":"en"},{"givenName":"浩爾","givenNameLang":"ja"},{"givenName":"コウジ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3282","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"真珠養殖過程中におけるアコヤガイの生活活動の変化が真珠形成に及ぼす影響　2. 表面構造と光沢の季節的変化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"真珠養殖過程中におけるアコヤガイの生活活動の変化が真珠形成に及ぼす影響　2. 表面構造と光沢の季節的変化","subitem_title_language":"ja"},{"subitem_title":"The influence of the life-activity upon pearl formation in the pearl culture of Pinctada martensii (Dunker) II.
