The apparatus consists of a pair of plastics celles with platinum electrodes at the bottom as shown in Fig. 1. A water saturated wood specimen was inserted between the cells, clamped, and four sides of the specimen were coated with paraffine. In order to give a concentration gradient of the solute in the specimen the solution of a given concentration was filled in cell-A and distilled water in cell-B, where increase in the concentration was measured by use of the electric conductivity method (Fig. 2) at suitable time intervals. The measurements were carried out in three structural directions of Hinoki wood (Chamaecyparis obtusa Endl.) and Buna wood (Fagus crenata Blume) at 40℃, and the solutes used in this experiment were NaF, Na-PCP, K_2Cr_2O_7,and H_3BO_3. The results obtained are as follows : 1) The apparatus can be used for many electrolytic solutions with exception of some solutions of lower specific electric conductivity such as H_3BO_3 solution. 2) Coefficients of variation for regression coefficient of the diffusion curves, i. e. the rate of transfer of the solute, were less than 3 percent as five measurements were made for each specimen (Table 2). 3) The accuracy of the measurement was high enough in comparison with the variation of diffusion coefficients among the specimens. 4) From the ratio of the diffusion coefficients in longitudinal to transverse directions it was suggested that the specimens for longitudinal direction have about ten times thickness for the transverse directions.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_3_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00062275","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00757373","subitem_source_identifier_type":"PISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"佐道, 健","creatorNameLang":"ja"},{"creatorName":"サドウ, タケシ","creatorNameLang":"ja-Kana"},{"creatorName":"Sadoh, Takesi","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"福山, 萬治郎","creatorNameLang":"ja"},{"creatorName":"フクヤマ, マンジロウ","creatorNameLang":"ja-Kana"},{"creatorName":"Fukuyama, Manjiro","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-20"}],"displaytype":"detail","filename":"KJ00000078792.pdf","filesize":[{"value":"596.3 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"KJ00000078792.pdf","url":"https://kpu.repo.nii.ac.jp/record/4793/files/KJ00000078792.pdf"},"version_id":"5dc2addb-e271-42f2-8933-546b869f52c7"}]},"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"}]},"item_title":"飽水木材中の溶質拡散 I : 電解質の拡散係数の測定(林学部門)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"飽水木材中の溶質拡散 I : 電解質の拡散係数の測定(林学部門)","subitem_title_language":"ja"}]},"item_type_id":"3","owner":"14","path":["410"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-02-20"},"publish_date":"2017-02-20","publish_status":"0","recid":"4793","relation_version_is_last":true,"title":["飽水木材中の溶質拡散 I : 電解質の拡散係数の測定(林学部門)"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2024-04-19T05:14:04.856211+00:00"}
