An orientation distribution function for preferentially oriented powder particles is obtained from the distribution function, ρ(α), defined by ρ(α)=I_<pre>(α)/I_<ran>(α) where I_<pre>(α) and I_<ran>(α) are respectively the intensities for a hk〓 reflection from preferentially and randomly oriented powder particles; α is an angle between the (hk〓) plane and the plane of preferred orientation [the planes of preferred orientation are (010) for γ_<II>-Li_2ZnSiO_4 and (100) for p-iodobenzoic acid]. Two analytical functions of Gaussian and Cauchy types as a function of α were examined to approximate the orientation distribution function. Multiplying the intensities I_<ran>(α) by the values of these two functions, we calculated powder intensity profiles and compared them with the observed intensity profiles. It was found that, although the Cauchy-type function gives a better approximation for representing distribution function ρ(α) vs α for both the two compounds, both the intensity profiles calculated by using the two functions give a satisfactory agreement with the observed profiles. The fact that these two functions have very similar preferred orientation effects on the powder intensity profiles can be explained in terms of a lack of the strong intensities of I_<ran>(α) with small values of α, and therefore we cannot say positively which of the two functions is better to represent the distribution of preferred orientation in powder sample in this study.|高木・山口〔1〕は反射型粉末X線回折法において,試料の結晶構造がわかっている場合回折強度の実測値と計算値を比べることにより板状粉末試料の選択配向分布を求める方法を与えた。本論文では,彼らの方法をより一般化しγ_<II>-Li_2ZnSiO_4及びp-ヨード安息香酸に適用し,これらの粉末試料の選択配向分布を調べた。粉末試料における配向面の分布を表わす関数N(α)は,ρ(α)=I_<pre>(α)/I_<ran>(α)で定義された関数のαについての分布から求めた。ここで,I_<pre>(α)とI_<ran>(α)は粉末試料が,選択配向した時と,選択配向しない時のhkl反射の回折強度を,αは(hkl)面と配向面とのなす角度を示す。〔γ_<II>-Li_2ZnSiO_4及びp-ヨード安息香酸の配向面はそれぞれ(010)面と(100)面である。〕ガウス型関数とコーシー型関数を使ってN(α)を近似し,これら両関数とI_<ran>(α)を用いてI_<pre>(α)を求め、X線回折図形を計算し,実測の回折図形と比較した。以上の結果,N(α)はコーシー型関数により,より精度よく近似されることがわかったが,両関数を使用して求めた回折図形は,共に実測した回折図形とよく一致した。これについては,両化合物とも選択配向の効果が顕著に現われるαの小さな値の範囲に,強い回折強度を持つ反射が存在しないことで説明される。したがって,本研究では,粉末試料におけるN(α)を表現するためにガウス型関数とコーシー型関数とでは,どちらがより近似式であるかということを明確にすることはできなかった。","subitem_description_type":"Other"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"大阪教育大学","subitem_publisher_language":"ja"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00028200","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03737411","subitem_source_identifier_type":"ISSN"}]},"item_1708778167539":{"attribute_name":"DCMI資源タイプ","attribute_value":"Text"},"item_1709629085853":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Article"}]},"item_1709629224652":{"attribute_name":"資料種別(NIIタイプ)","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1709631006745":{"attribute_name":"TD番号","attribute_value_mlt":[{"interim":"TD00010512"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"YAMAGUCHI, Hiroshi","creatorNameLang":"ja"},{"creatorName":"ヤマグチ, ヒロシ","creatorNameLang":"ja-Kana"},{"creatorName":"山口, 弘","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"NAKATA, Kazuaki","creatorNameLang":"ja"},{"creatorName":"ナカタ, カズアキ","creatorNameLang":"ja-Kana"},{"creatorName":"仲田, 和明","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"KURISU, Arifumi","creatorNameLang":"ja"},{"creatorName":"クリス, アリフミ","creatorNameLang":"ja-Kana"},{"creatorName":"栗栖, 有文","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"TAKAKI, Yoshito","creatorNameLang":"ja"},{"creatorName":"タカキ, ヨシト","creatorNameLang":"ja-Kana"},{"creatorName":"高木, 義人","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"AKATSUKA, Kyube","creatorNameLang":"ja"},{"creatorName":"アカツカ, キュウベエ","creatorNameLang":"ja-Kana"},{"creatorName":"赤塚, 久兵衛","creatorNameLang":"en"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_title":"Preferred Orientation of Plate-Like Particles in Reflection -Type Powder Diffractometry-Application to γ_<II>-Li_2ZnSiO_4 and p-Iodobenzoic Acid Powders-","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Preferred Orientation of Plate-Like Particles in Reflection -Type Powder Diffractometry-Application to γ_<II>-Li_2ZnSiO_4 and p-Iodobenzoic Acid Powders-","subitem_title_language":"en"},{"subitem_title":"反射型粉末回折法における板状試料の選択配向-γ_<II>-Li_2ZnSiO_4及びp-ヨード安息香酸粉末試料への適用-"}]},"item_type_id":"40003","owner":"14","path":["1709456339410"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-12-07"},"publish_date":"2009-12-07","publish_status":"0","recid":"2069927","relation_version_is_last":true,"title":["Preferred Orientation of Plate-Like Particles in Reflection -Type Powder Diffractometry-Application to γ_<II>-Li_2ZnSiO_4 and p-Iodobenzoic Acid Powders-"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2024-07-20T12:38:34.425826+00:00"}
