The apparatus used in these experiments was the same as that described in a previous report except for some modifications in the design of the diffusion cell and electric circuit. The test specimens were disks the size of 4cm in diameter, and 1cm (for longitudinal diffusion) or 0.15cm (for transverse diffusion) in thickness. The results obtained are as follows : (1) The deviations of measured values in the diffusion curves at each steady state, i.e. the coefficients of variation for regression coefficient in the amount of solute-transfer vs. time curves were less than 2 per cent (Fig. 2). (2) A plot of log D ((cm)^2/day×(10)^<-3>) against 1/T showed approximately linear relationship except for the diffusion of Na-PCP in R-direction of Hinoki (Fig. 3 and 4). (3) There was no difference in the diffusion coefficients between T- and R-directions of Hinoki, while the tangential diffusion coefficient of Buna was about twice as great as the radial value. The longitudinal diffusion coefficients of both the species were approximately 5-36 times as great as the transverse values (Table 3). (4) The diffusion rate of KCl was appreciably greater than that of Na-PCP in all cases. This tendency was especially more pronounced in the case of transverse diffusion (Table 4). (5) The apparent activation energy and the mean temperature coefficient in the diffusion process of Na-PCP were slightly greater than the corresponding values of KCl; further those of transverse diffusion were generally greater than values in longitudinal diffusion. In particular, these phenomena were remarkable in Hinoki (Table 5). (6) It was assumed that the apparent activation energy and the mean temperature coefficient in the diffusion process of electrolytes might be dependent upon the dimensions of the individual effective capillaries. Particularly they might be depend upon the mean free path of the solute traversed per unit distance in the diffusion direction, and also the number of capillaries whose radius was smaller than that of the mean free path.","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":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"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":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"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":[{}]}]},"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":"KJ00000078828.pdf","filesize":[{"value":"838.1 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"KJ00000078828.pdf","url":"https://kpu.repo.nii.ac.jp/record/4829/files/KJ00000078828.pdf"},"version_id":"1c843cec-72f2-4c2d-bee4-79bc76c34d27"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper"}]},"item_title":"The diffusion of solute through wood saturated with water II : Effects of temperature on the diffusion of electrolytes (Forestry)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The diffusion of solute through wood saturated with water II : Effects of temperature on the diffusion of electrolytes (Forestry)","subitem_title_language":"en"}]},"item_type_id":"3","owner":"4","path":["412"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-02-20"},"publish_date":"2017-02-20","publish_status":"0","recid":"4829","relation_version_is_last":true,"title":["The diffusion of solute through wood saturated with water II : Effects of temperature on the diffusion of electrolytes (Forestry)"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2024-05-15T06:38:11.857238+00:00"}
